1 Supreme Performance of High Precision

2 1 Construction Carriage End Cap End Seal Rail Ball Retainer Bottom Seal Characteristics MSC stainless steel series are applied two rows with Gothicarch groove and designed to contact angle of 4 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. Fourway Equal Load The two trains of balls are allocated to a Gothicarch groove contact angle at 4, thus each train of balls can take up an equal rated load in all four directions. Smooth Movement with Low Noise The simplified design of circulating system with strengthened synthetic resin accessories makes the movement smooth and quiet. Ultra Compact The ultra compact design is suit to the compact application with limited in space. Ball Retainer Design with ball retainer can prevent ball form dropping. Interchangeability For interchangeable type of linear guideway, the dimensional tolerances are strictly maintained 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 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. 01

End seal Monodirectional seal for low frictional resistance required. Bottom Seal Preventing the inclusion of foreign matters from bottom of carriage. End seal Bottom Seal (2) Code of contamination protection THe codes for selection of dust protection accessory are shown as Table. Table Code of contamination protection () Resistance value of Seal The maximum resistance value of seals type LL when it is applied with grease is shown as Table 4.

6 (4) Caps for rail mounting hole A special designed of cap is used to cover the bolt hole to prevent the foreign matters from entering the carriage. The cap is mounted by using a plastic hammer with a flat pad placed on the top, until the top of cap is flush to the top surface of rail (see Fig. ). The dimension of caps for different sizes of rail is shown as Table.

7 7 The Shoulder Height and Corner Radius for Installation The mounting surface of rails and carriages are machined precisely for aiding in positiioning and assemble with high accuracy. The shoulder height and corner radius providing enough mounting space for not to interfere with chamfers made on rails and carriages. The dimensions of shoulder height and corner radius are shown as Table 6 and with bottom seal are shown as Table 7. h2 h1 H2 Table 6 Shoulder height and corner radius of mounting surface Unit:mm r1 (max.) r2 (max.) h1 h2 H Table 7 Shoulder height and corner radius of mounting surface with bottom seal Unit:mm h1 H
