1 The Characteristics of MI s The Classification Chart of MI s 2 (1) igh positioning accuracy, high repeatability The MI linear guideway is a design of rolling motion with a low friction coefficient, and the difference between dynamic and static friction is very small. Therefore, the stick-slip will not occur when submicron feeding is making. (2) ow frictional resistance, high precision maintained for long period The frictional resistance of a linear guideway is only 1/2th to 1/4th of that in a slide guide. ith a linear guideway, a well lubrication can be easily achieved by supplying grease through the grease nipple on carriage or utilizing a centralized oil pumping system, thus the frictional resistance is decreased and the accuracy could be maintained for long period. (3) igh rigidity with four-way load design The optimum design of geometric mechanics makes the linear guideway to bear the load in all four directions, radial, reversed radial, and two lateral directions. Furthermore, the rigidity of linear guideway could be easily achieved by preloading carriage and by adding the number of carriages. (4) Suitable for high speed operation Due to the characteristic of low frictional resistance, the required driving force is much lower than in other systems, thus the power consumption is small. Moreover, the temperature rising effect is small even under high speed operation.

Calculate the load applied on each carriage Convert the load of block exerts in each direction into equivalent load To obtain a model which is most suitable for your service conditions of the linear guideway system, the load capacity and service life of the model must be taken into consideration. To verify the static load capacity, the basic static load rating (C) is taken to obtain the static safety factor. The service life can be obtained by calculating the nominal life based on basic dynamic load rating. As the raceways or rolling elements are subjected repeated stresses, the service life of a linear guideway is defined as the total running distance that the linear guideway travel until flaking occurs. 4.1 Basic Static oad Rating (C) A localized permanent deformation will develop between raceways and rolling elements when a linear guideway receives an excessive load or a large impact. If the magnitude of the deformation exceeds a certain limit, it could obstruct the smooth motion of the linear guideway. The basic static load rating (C) refers to a static load in a given direction with a specific magnitude applied at the contact area under the most stress where the sum of permanent deformation develops between the raceway and rolling elements is.1 times of the diameter of rolling ball. Therefore, the basic static load rating sets a limit on the static permissible load. 4.2 Static ermissible Moment (M) Calculate the static safety factor The safety factor verified by basic static load rating and max equivalent load hen a moment is applied to a linear guideway, the rolling balls on both ends will receive the most stress among the stress distribution over the rolling elements in the system. The static permissible moment (M) refers to a static NO Verification of safety factor moment in a given direction with specific magnitude applied at the contact area under the most stress where the sum of permanent deformation develops between the raceway and rolling elements is.1 times the diameter YS of rolling elements. Therefore, the static permissible moment sets a limit on the static moment. In linear guideway Calculate mean load Averaging the applied loads that fluctuate during operation and convert them into mean load system, the static permissible moment is defined as M, MY, MR three directions.

4.3 Static Safety Factor ( fs ) Due to the impact and vibration while the guideway at rest or moving, or the inertia from start and stop, the linear guideway may encounter with an unexpected external force. Therefore, the safety factor should be taken into consideration for effects of such operating loads. The static safety factor ( fs) is a ratio of the basic static load rating (C) to the calculated working load. The static safety factor for different kinds of application is shown as Table. Machine Type oad Condition fs (ower limit) Regular industrial Normal loading condition 1. ~ 1.3 machine ith impact and vibration 2. ~ 3. Normal loading condition 1. ~ 1.5 Machine tool ith impact and vibration 2.5 ~ 7. Standard value of static safety factor 4.4 Basic Dynamic oad Rating (C ) ven when identical linear guideways in a group are manufactured in the same way or applied under the same condition, the service life may be varied. Thus, the service life is used as an indicator for determining the service life of a linear guideway system. The nominal life () is defined as the total running distance that 9% of identical linear guideways in a group, when they are applied under the same conditions, can work without developing flaking. The basic dynamic load rating (C ) can be used to calculate the service life when linear guideway system response to a load. The basic dynamic load rating (C ) is defined as a load in a given direction and with a given magnitude that when a group of linear guideways operate under the same conditions. As the rolling element is ball, the nominal life of the linear guideway is 5 km. Moreover, as the rolling element is roller, the nominal life is 1 km. 4.5 Calculation of Nominal ife () The nominal life of a linear guideway can be affected by the actual working load. The nominal life can be calculated base on selected basic dynamic load rating and actual working load. The nominal life of linear guideway system could be influenced widely by environmental factors such like hardness of raceway, environmental temperature, motion conditions, thus these factors should be considered for calculation of nominal life. ardness factor f In order to ensure the optimum load capacity of linear guideway system, the hardness of raceway must be RC58~64. If the hardness is lower than this range, the permissible load and nominal life will be decreased. For this reason, the basic dynamic load rating and the basic static load rating should be multiplied by hardness factor for rating calculation. See figure below. The hardness requirement of MI linear guideway is above RC58, thus the f =1.. ardness factor ( f ) 1..9.8.7.6.5.4.3.2.1 6 5 4 3 2 1 Raceway hardness (RC) oad factor f w Although the working load of liner guideway system can be obtained by calculation, the actual load is mostly higher than calculated value. This is because the vibration and impact, caused by mechanical reciprocal motion, are difficult to be estimated. This is especially true when the vibration from high speed operation and the impact from repeated start and stop. Therefore, for consideration of speed and vibration, the basic dynamic load rating should be divided by the empirical load factor. See the table below. Temperature factor f T hen operating temperature higher than 1, the nominal life will be degraded. Therefore, the basic dynamic and static load rating should be multiplied by temperature factor for rating calculation. See figure below. The assemble parts of MI guideway are made of plastic and rubber, therefore, the operating temperature below 1 is strongly recommend. For special need, please contact us.

5 Friction Coefficient Calculation of orking oad 6 A linear guideway manipulates linear motion by rolling elements between the rail and the carriage. In which type of motion, the frictional resistance of linear guideway can be reduced to 1/2th to 1/4th of that in a slide guide. This is especially true in static friction which is much smaller than that in other systems. Moreover, the difference between static and dynamic friction is very little, so that the stick-slip situation does not occur. As such low friction, the submicron feeding can be carried out. The frictional resistance of a linear guideway system can be varied with the magnitude of load and preload, the viscosity resistance of lubricant, and other factors. The frictional resistance can be calculated by the following equation base on working load and seals resistance. Generally, the friction coefficient will be different from series to series, the friction coefficient of ball type is.2~.3 (without considering the seal resistance) and the roller type is.1~.2(without considering the seal resistance) The load applied to a linear guideway system could be varied with several factors such as the location of the center gravity of an object, the location of the thrust, and the inertial forces due to acceleration and deceleration during starting and stopping. To select a correct linear guideway system, the above conditions must be considered for determining the magnitude of applied load. xamples for calculating working load Type Operation Conditions quations 3 l2 F Frictional resistance (kgf ) μ Dynamic friction coefficient orizontal application: 4 l3 F 2 orking load (kgf ) Uniform motion f Seal resistance (kgf ) or at rest 1 l4 l1.15 Friction coefficient ( ).1.5 Overhung horizontal application: Uniform motion 4 1 3 2 l2 or at rest l1.1.2 l4 F l3 oad ratio (/C) : orking load C: Basic dynamic load rating l3 Relationship between working load and friction coefficient 4 F Vertical 1 application: l1 1T Uniform motion or at rest 3 l4 2 2T l2 14 Friction Coefficient General Catalog 15

The mean load (m) is the load that the service life is equivalent to the system which under the varying load conditions.

Construction Upper Retainer Carriage nd Cap eavy oad MSA-A Type MSA- Type MSA-S Type nd Seal Rail Grease Nipple Ball 45 ower Retainer Bottom Seal 45 B. Characteristics Installed from top side of carriage with the thread length longer than MSA- type. This type offers the installation either from top or bottom side of carriage. Square type with smaller width and can be installed from top side of carriage. The trains of balls are designed to a contact angle of 45 which enables it to bear an equal load in radial, reversed radial and lateral directions. Therefore, it can be applied in any installation direction. Furthermore, MSA series can achieve a well balanced preload for increasing rigidity in four directions while keeping a low frictional resistance. This is especially suit to high precision and high rigidity required motion. The patent design of lubrication route makes the lubricant evenly distribute in each circulation loop. Therefore, the optimum lubrication can be achieved in any installation direction, and this promotes the performance in running accuracy, service life, and reliability. Ultra eavy oad igh Rigidity, Four-way qual oad The four trains of balls are allocated to a circular contact angle at 45, thus each train of balls can take up an equal rated load in all four directions. Moreover, a sufficient preload can be achieved to increase rigidity, and this makes it suitable for any kind of installation. Smooth Movement with ow Noise Self Alignment Capability The self adjustment is performed spontaneously as the design of face-to-face (DF) circular arc groove. Therefore, the installation error could be compensated even under a preload, and which results in precise and smooth linear motion. Interchangeability MSA-A Type MSA- Type MSA-S Type The simplified design of circulating system with For interchangeable type of linear guideway, the strengthened synthetic resin accessories makes the dimensional tolerances are strictly maintained movement smooth and quiet. within a reasonable range, and this has made the random matching of the same size of rails and carriages possible. Therefore, the similar preload and All dimensions are same as MSA-A except the length is longer, which makes it more rigid. All dimensions are same as MSA- except the length is longer, which makes it more rigid. All dimensions are same as MSA-S except the length is longer, which makes it more rigid. accuracy can be obtained even under the random matching condition. As a result of this advantage, the linear guideway can be stocked as standard parts, the installation and maintenance become more convenient. Moreover, this is also beneficial for shortening the delivery time. 3 eavy oad Type, MSA Series General Catalog 31

Characteristics 45 Bottom Seal The trains of balls are designed to a contact angle of 45 which enables it to bear an equal load in radial, reversed radial and lateral directions. Therefore, it can be applied in any installation direction. Furthermore, MSB series can achieve a well balanced preload for increasing rigidity in four directions while keeping a low frictional resistance. This is especially suit to high precision and high rigidity required motion. The patent design of lubrication route makes the lubricant evenly distribute in each circulation loop. Therefore, the optimum lubrication can be achieved in any installation direction, and this promotes the performance in running accuracy, service life, and reliability. This type offers the installation either from top or bottom side of carriage. Square type with smaller width and can be installed from top side of carriage. Compact, Four-way qual oad Self Alignment Capability eavy oad Compact design of the carriage with the four trains of balls are allocated to a circular contact angle at 45, The self adjustment is performed spontaneously as the design of face-to-face (DF) circular arc groove. MSB- Type MSB-S Type thus each train of balls can take up an equal rated load Therefore, the installation error could be compensated in all four directions. Moreover, a sufficient preload even under a preload, and which results in precise and can be achieved to increase rigidity, and this makes it smooth linear motion. suitable for any kind of installation. Smooth Movement with ow Noise Interchangeability The simplified design of circulating system with For interchangeable type of linear guideway, the strengthened synthetic resin accessories makes the dimensional tolerances are strictly maintained movement smooth and quiet. within a reasonable range, and this has made the random matching of the same size of rails and carriages possible. Therefore, the similar preload and All dimensions are same as MSB-T except the length is longer, which makes it more rigid. All dimensions are same as MSB-TS except the length is longer, which makes it more rigid. accuracy can be obtained even under the random matching condition. As a result of this advantage, the linear guideway can be stocked as standard parts, the installation and maintenance become more convenient. Moreover, this is also beneficial for 38 Compact Type, MSB Series shortening the delivery time. General Catalog 39

Characteristics MSC stainless steel series are applied two rows with Gothic-arch groove and designed to contact angle of 45 which enables it to bear an equal load in radial, reversed radial and lateral directions. Furthermore, ultra compact and low friction resistance design is suit to compact equipment. The lubrication route makes the lubricant evenly distribute in each circulation loop. Therefore,the optimum lubrication can be achieved in any installation direction, and this promotes the performance in running accuracy, service life, and reliability. Four-way qual oad Smooth Movement with ow Noise The two trains of balls are allocated to a Gothic-arch The simplified design of circulating system with groove contact angle at 45, thus each train of balls can strengthened synthetic resin accessories makes the takeup an equal rated load in all four directions. movement smooth and quiet. Ultra Compact Interchangeability The ultra compact design is suit to the compact For interchangeable type of linear guideway, the application with limited in space. dimensional tolerances are strictly maintained within a reasonable range, and this has made the Ball Retainer random matching of the same size of rails and carriages possible. Therefore, the similar preload and Design with ball retainer can prevent ball form accuracy can be obtained even under the random dropping. matching condition. As a result of this advantage, the linear guideway can be stocked as standard parts, the installation and maintenance become more convenient.

12.6 Roller Chain Type, SMR Series A. Construction Carriage nd Cap nd Seal Grease Nipple Inner Seal Roller Chain 45 Roller Bottom Seal Rail 45 B. Characteristics The roller chain type linear guideway, SMR series, equip with rollers instead of the ball, and therefore the SMR series can provide higher rigidity and loading than the normal type with the same size. Besides, the patent of roller chain design can make the movement smooth and stability, especially suit for the requests of high accuracy, heavy load and high rigidity. Ultra eavy oad The Optimization Design of Four Direction oad SMR linear guideway through rollers have a line Through the structure stress analysis of finite element contact with carriage and rail. Relative to the general method, SMR series have four trains of rollers are type linear guideway through balls have a point designed to a contact angle of 45 and the section contact; the SMR type linear guideway can offer lower design for high rigidity. xcept for bearing heavier elastic deformation while bearing the same load. Base loads in radial, reversed radial and lateral directions, a on the rollers have the same outer diameter with balls, sufficient preload can be achieved to increase rigidity, the roller can bear the heavier load. The excellent and this makes it suitable for any kind of installation. characteristics of high rigidity and ultra heavy load can suitable for the high accuracy application that heavy load is processed even more. Roller Chain Design, Smooth Movement The concise and smooth design of circulating system with strengthened synthetic resin accessories and cooperating with the roller chain, these can avoid interference between rollers and make the rollers more stability during passing in and out the load district. Besides, the roller chain can keep the roller move in a line and improve the movement most smooth substantially. ow Noise, Good ubricant ffect The roller chain design avoids interference between rollers, lowers the operating noise, and can keep the lubricant between the rollers and roller chain effectively. Moreover, improve the movement smooth and service life of the whole, can meet high accuracy, high reliability and smooth and stability. C.
