Roller screw products
Five product families covering standard high-load motion, compact inverted actuators, fine-lead recirculating and differential screws, and the bearing units that support them.
RV / HRV Roller Screws
The workhorse planetary roller screw for high-thrust, high-duty linear motion across the widest range of applications.
View RV →RVI Inverted Roller Screws
An inverted arrangement where the nut rotates and the screw remains fixed — ideal for compact, integrated actuators.
View RVI →RVR Recirculating Roller Screws
Recirculating rollers deliver very small leads for high-resolution positioning where a standard roller screw cannot.
View RVR →RVD Differential Roller Screws
The differential principle produces extremely fine effective leads for precise, high-reduction linear motion.
View RVD →BU Support Bearing Units
Pre-engineered axial bearing units that support and locate the screw shaft in a complete actuator assembly.
