Product catalog summary
Performance Specifications:
The FMR Series Roller Screw Servo Actuator supports loads from 500 kg to 100 tons, with a stroke up to 4 meters. It reaches speeds of 1 m/s and accelerations of 1g. The actuator uses a high-efficiency roller screw for continuous duty cycles, with positioning accuracy of 0.02 mm and closed-loop accuracy of 0.01 mm. It includes a pressure sensor for force accuracy within 0.5%. Designed for longevity, it lasts 10-15 times longer than ball screw cylinders and has an IP65 protection level, suitable for harsh environments. It is maintenance-free due to high-performance lubricants.
Comparison with Ball Screws:
Planetary roller screws offer three times the static load capacity and 15 times the lifespan of ball screws. They provide higher dynamic and static loads due to threaded rollers, enhancing impact resistance. They support higher rotational speeds and accelerations, with non-circulating designs allowing double the rotational speed and accelerations up to 3g.
Technical Advantages:
The lead of planetary roller screws can be smaller than ball screws, allowing precise movement without reduction gears. Changes in lead do not affect the screw shaft and nut size. Numerous contact points increase rigidity and impact resistance.
Performance Tables:
Performance tables for models (FMR25, FMR35, FMR40, FMR50, FMR60, FMR80, FMR200) include specifications like screw diameter, lead, rated force, maximum force, speed, efficiency, torque, dynamic load, inertia, stroke, RPM, acceleration, weight, backlash, lead tolerance, and repeat accuracy.
Graphical Data:
Graphs show critical buckling force, illustrating load and stable length relationships for different FMR models.

The difference between planetary roller screws and ball screws Both planetary roller screws and ball screws are suitable for use with Hertz law. Planetary roller screws and ball screws have similar structures, but the difference lies in the load transfer element,which are threaded rollers, rather than balls. Our main advantage has numerous contact points to support the load. According to Hertz law, the static load capacity of planetary roller screws is 3 times that of ball screws, and their lifespan is 15 times that of ball screws.
