RT Series
The RT Series offers outstanding rigidity, high load capacity, and accurate rotary positioning, ensuring stable performance even in the most demanding machining environments.
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 impellers
- Machining of turbine blades
- Machining of dies and molds
Features
- 2-Rotary Axes
Allows machining of various workpieces. - Available in 2 Table Diameters
Available in table diameters from 80, 100 mm. - Zero Backlash Technology
RollerDrive Achieves Zero-backlash - No Clamping
No clamping motion necessary because the mechanism is free of play.
