RS Series
The RS Series combines precision, durability, and space-saving design to provide reliable rotary motion for a wide range of CNC machining and automation applications.
Over View
In terms of performance, Sankyo’s roller gear does for rotary motions what the ball screw does for linear motions. The roller gear cam mechanism consists of a roller gear and globoidal cam. Similar to the preloading structure of a ball screw, the roller gear has no backlash, and transfers power by rolling contact for strong rigidity and excellent efficiency. And no clamping is necessary.
Application
- Machining of artificial bones and joints
- Machining of automotive engine parts
- Lens polishers
Features
- Available in 4 Table Diameters
Available in table diameters from 100 to 240 mm. - Zero Backlash Technology
RollerDrive achieves zero-backlash. - High Accuracy
Rotary positioning accuracy 10 seconds (RS200, RS240) maximum. - No Clamping
No clamping motion necessary because the mechanism is free of play. - Exclusively for Vertical Mounting
Exclusively for vertical mounting.
