The modular design enables the rotary stage to be easily combined with other items of the same size.

The item with order number 21160-251 can be clamped axially against the housing using two clamping levers and secured against accidental movement. Torque M1 increases to 30 Nm with tightened clamping levers with max. 2.5 Nm tightening torque per clamping lever. Clamping levers must be released before the knob is turned, otherwise there is a risk of damage to the transmission.

Items 21161-10-08 and 21161-10-12 can be clamped against the turntable housing using rotary stage clamp 21161-11 and thus secured against unintentional adjustment.

1) Space requirement for clamping lever
