Lim-Tec FMR Series Roller Screw Servo Actuato
Lim-Tec Performance FMR： Load range: From 500kgs – 100 Tons Stroke Max.4 Meters. Max. Speed:1m/s; Max. Acceleration: 1g High Efficiency roller screw, continuously duty cycle. Positioning Accuracy 0.02mm; Closed loop: 0.01mm Force Accuracy: closed-loop precision 0.5%; Built-in pressure sensor available Ultra-long lifespan, 10-15 times longer than similar ball screw electric cylinders. High protection level IP65, suitable for harsh working environments. High-performance lubricants, maintenance-free for life
Capacity and lifespan The advantages of planetary roller screws lie in the ability to provide higher rated dynamic and static load. The use of threaded rollers instead of balls allows the load to be rapidly released through numerous contact points, thereby providing higher impact resistance

Both planetary roller screws and ball screws are suitable for use with Hertz law. 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
Speed and acceleration Planetary roller screws can provide higher rotational speeds and higher accelerations. RV series planetary roller screws are noncirculating, which allows for double rotational speed compared to ball screws, and accelerations of up to 3g
