Inverted Planetary Roller Screw

When your application demands extreme force density, microscopic precision, and a compact footprint that traditional ball screws or linear actuators simply cannot achieve,

By flipping the traditional design mechanics, the inverted configuration integrates the roller-bearing planetary nut directly into the actuator housing or motor rotor. This eliminates wasted space, drastically reduces moving mass, and delivers unparalleled power density.

Customizable Sizes
Every machine is different. We don’t force you into a standard catalog box. We offer fully customizable screw diameters, thread leads, nut shapes, and shaft ends to perfectly match your existing design.

Best Used For:

• Robotics & Humanoids: High-force linear joints and compact robotic arms.
• Automotive & Factory Assembly: Servo welding guns, rivet tools, and precision press machines.
• Aerospace: Flight controls, fin actuators, and landing gear systems.
• Medical Equipment: High-capacity surgical tables and precise laboratory pumps.
