Preloaded tooth engagement
The flexspline engages across a broad tooth band, removing measurable backlash while keeping the compact coaxial package.
Flexspline motion under load, measured at the output flange.

Numbers are presented as selection windows for preliminary sizing. Final allowable torque, average speed, and life rating depend on the duty cycle and mounting temperature.

FAQ
Selection questions engineers ask first
Use a component set when the machine frame already supplies bearing support, sealing, and alignment. Choose a gear unit when the output bearing, housing, and grease system need to arrive as one controlled assembly.
Yes, but compare lost motion, torsional stiffness, moment load, and allowable average speed, not only nominal torque. The best choice changes with shock load and positioning duty cycle.
Provide ratio, peak torque in Nm, average output rpm, duty cycle, target life in hours, orientation, ambient temperature, and any cleanroom or vacuum handling constraints.
Need a gearbox sized for a robot joint or wafer stage?
Send the duty cycle and mounting envelope. We will return a ratio shortlist, torque margin notes, and datasheet links for review.
