1 Series Overview SC Series The SC series has been designed for use mainly as a vertical axis unit, taking advantage of the fact that the drive is fitted directly inside of the carriage (eliminating movement of the cables) and with the extruded body as the only mobile part.

The Components 2 Extruded Bodies The aluminium extrusions used for the SC series are designed and manufactured in cooperation with a leading company in this field to obtain the right combination of high mechanical strength and reduced weight. Aluminium alloy 6060 is used (see page 19 for further information). The dimensional tolerances comply with UNI 3879 standards. T-slots are provided for fast, hassle-free mounting of accessories (proximity switch runner, etc.). Power cables, air hoses, and other elongated accessories can be passed through the aluminum extrusion by means of the unit s cable slot. Threaded holes are provided at one end of the extrusion for mounting of robot gripper mechanisms and EOA (End-of- Arm) tooling. Driving Belt The SC actuator uses steel reinforced polyurethane drive belts with AT type pitch and parabolic profiles. This type of belt is ideal because of its high load transmission characteristics, compact size and low noise. Used in conjunction with a backlash-free pulley, smooth alternating motion can be achieved. Optimization of the maximum belt width-to-body dimension ratio enables the following performance characteristics to be achieved: High speed Low noise Low wear Long life Carriage The carriage is an enveloping structure that houses the entire linear motion system. The carriage consists of a drive pulley and two driven pulleys. The external parts are made of anodized aluminium. Dimensions vary according to the actuator s size. One of the three set-ups shown on pages 17 & 18 can be used for fast, simple assembly of the SC series. For added protection, the carriage is also fitted with specific seals (brushes).

3 The Linear Motion System The linear motion system has been designed to meet high load, high speed, and maximum acceleration conditions. The SC series features the following linear motion system: SC series with ball bearing guides Two ball bearing guides with high load capacities are mounted onto two seats on the outer sides of the aluminium body. The carriage of the linear unit is assembled on four preloaded ball bearing blocks with engineered polymer retention cages. The linear motion system described here offers: High speed and acceleration High load capacity High permissible bending moments Low friction Long life Low noise Maintenance free The four-ball row configuration enables the carriage to withstand equal loading evenly in the radial (normal) and lateral (transverse) directions. The four blocks have seals on both ends and, when necessary, an additional scraper can be fitted for very dirty or contaminated conditions. Lubrication reservoirs (pockets) installed on the front of the ball bearing blocks supply the right amount of lubricant, promoting maintenance-free operation.

5 Main Technical Characteristics The sectioned drawings on the previous page showing the main characteristics help guide the process of an initial actuator size selection. For a final selection, refer to the data and dimensions indicated in the pages listed at the end of each table.

These values do not relate to the theoretical maximum permitted load capacity of the linear motion system. See page The load capacity of the SC series depends on the linear motion system used and may vary according to the loading direction: radial or lateral. The maximum load in an axial direction depends on the type of driving belt used. The maximum recommended values for the radial load (Fz) and the lateral load (Fy) indicated above incorporate a substantial factor of safety to ensure long life cycles. Experience shows that these values ensure safe static loading and adequate life for most applications. For special conditions (such as high shocks, vibrations, dusty environments, acceleration forces and high bending moments, etc), contact Rollon for further technical advice. Maximum permissible values for speed, acceleration and positioning repeatability can be decreased in the presence of high loads. Fx (axial) Fz (radial) Fy (lateral)

9 Transmission Features The SC series can be fitted as standard with different types of movement transmissions: Planetary gears Right angle transmission gears Versions with simple shaft Versions with hollow shaft Versions with planetary gears Planetary gears are used for highly dynamic robotic, automation, and handling applications requiring high torque or frequent reversing and are capable of high level precision requirements. Standard models are available with backlash from 8 to 20 and with a reduction ratio from 3:1 to 1000:1. For assembly of nonstandard planetary gears, contact Rollon. Versions with right angle transmission gears Standard models are available with 5:1 to 150:1 transmission ratio. Versions with simple or hollow shafts If the linear units are not supplied directly with reduction units and the customer intends to use a different solution, the units can be equipped with simple or hollow shafts of different diameters. Transmission of torque to the drive pulley For versions equipped with reduction units or with a simple shaft, the drive pulley is coupled using a tapered spline. This system ensures long-lasting, high level precision, particularly for the case of high torque values and frequent reversals of motion. Only tab type coupling is available in the hollow shaft version. This system could result in backlash, especially in the case of high torque values. For further information, contact Rollon.

For further informations, contact Rollon.

Assembly and Accessories 14 The recirculating ball linear guides used in the SC series have equal load capacities in any direction. Therefore, the units can be installed in any orientation, even upside down, without any loss of load capacity or structural integrity. To install the SC units, we recommend using one of the two systems indicated below: Mounting by fixing brackets Unit: mm SC 65 SC 130 SC 160 A 112 213 266 Mounting bracket F A 0D1 L A B C E F D1 D2 H1 L SC 65 SP 20 7 16 6 7 10.5 6.5 20.7 50 SC 130 SP 20 7 16 6 7 10.5 6.5 20.7 50 E SC 160 SP 36.5 10 31 10 10.5 16.5 10.5 28.5 100 H1 0D2 B C Material: Anodized aluminium Direct mounting

15 Assembly and Accessories Fitting of the proximity switch Four threaded holes for the fitting of the proximity switches are provided on the sides of the carriage. When fitting the switches, be careful not to overtorque the switches in order to avoid damage to the sensor target. Promixity switch runner The zinc-coated, L-shaped section is fitted in the specific slot of the body and used to trip the proximity switch.

The carriages are equipped with polymer retention cages to avoid steel-steel contact between adjacent rotating elements and to reduce misalignment of these in the ball circuits. The cage also eliminates friction between the ball bearings, therefore, reducing wear. Lubrication reservoirs (pockets) installed on the ball bearing blocks release the right amount of lubricant to the areas where the loads are applied to the balls, thus promoting maintenance-free operation. Contact Rollon for the necessary analysis with high cyclic action and heavy loads.

Protection 16 Standard Protection Protection of the Ball Bearing Guides The blocks of the ball bearing guides are fitted with seals on both ends and, when necessary, an additional scraper can be fitted for very dusty conditions. Protection Using Brushes The carriages of the linear units are fitted with brush type seals on both ends to prevent penetration of impurities. Special Protection To use these linear units in very critical conditions, they can be fitted with a bellows system in addition to the standard protection. The bellows is fixed to the carriage and the ends of the linear unit by means of Velcro tape for easy assembly and disassembly and any replacements. The total length (L) of the linear unit will vary: add twice the length of the closed bellows package.

17 Multi-Axis System Previously, customers wishing to build multi-axis units have had to design, draw and manufacture all the elements necessary to assemble two or more axes. Rollon now offers the accessory mounting brackets and hardware necessary to configure the multi-axis units. The SC series is also pre-engineered to facilitate direct connection with the units of the ROBOT series. In addition to standard elements, Rollon also provides plates for special applications.
