Before you choose

Application guidance is based on the listed hardware and development resources. Confirm the software, sensors and integration your project needs.

Custom robot joints: what to confirm

Calculate load, inertia, thermal conditions and duty cycle. Confirm bearings, mounting flanges and mechanical differences between paired models before treating them as interchangeable.

Higher-speed motion: what to confirm

Check the torque-speed curve at your operating point, inertia, braking and bearing loads. Validate the complete mechanism at the intended speed.
