Roller Screw Actuator Products

Factory-direct roller screw actuator families for high-force electric cylinders, hydraulic replacement, compact robotics mechanisms, and drawing-based OEM motion systems.

Use this page as a pre-RFQ navigator: pick the product family, capture the correct engineering inputs, and move directly to sample validation criteria that buyers can approve.

How to Select the Right Path

Define rated force, peak force, stroke, speed, acceleration, and duty cycle.
Confirm envelope, mounting, rod end, anti-rotation, brake, sensor, and load-cell requirements.
Select the screw architecture: planetary roller screw, inverted roller screw, integrated servo cylinder, or custom assembly.
Set life, backlash, repeatability, axial play, and inspection acceptance criteria before quotation freeze.
Share drawing, STEP file, target quantity stage, delivery country, and lead-time goal with the initial RFQ.
