NOTICE!
Use grease to mount the OneGearDrive onto the shaft. For example, CASTROL Obeen Paste NH1, ARAL Noco Fluid or
similar. Use a key in the same material and quality as the hollow shaft.

3.7 Torque Restraint

The OneGearDrive requires a suitable torque restraint to resist the reaction torque. The torque arm with mounting set is
available as an option (see chapter 8.6.1 Torque Arm Set). Ensure that the torque arm does not create excessive constraining
forces, for example, due to the driven shaft running untrue. Excessive backlash can result in excessive shock torques in
switching or reversing operations.
