August 21, 2014 - Rollon releases R-Plus Rack and Pinion actuator that's suitable for fast, long travel applications with high accuracy requirements. TheR-Plus delivers consistent rigidity and high axial forces throughout its stroke. The R-Plus is attached to a robust 160- or 200-mm wide aluminum alloy beam with single piece long lengths that permit large loads with minimal deflection. It supports multiple carriages and associated pinions on the same axis, with each carriage capable of independent motion. The actuator is also effective in vertical applications and comes pre-installed with a precision speed reducer ready to mount the motor of the users choice.
The R-Plus System has self-sustaining aluminum extrusion profiles that house profile rails with recirculating ball bearings for large and balanced load capacity. The units are operated by hardened, tempered and ground steel rack and pinion helical teeth gears and a built-in lubrication kit allows the pinion to be easily greased for smooth operation and long life. Performance:
- Accelerations of up to 20 m/s2 (2 g’s)
- Repeatability values of ± 50 μm
- System single piece lengths between 700 and 5700 mm
