Description
Material
Body and rotary table Al alloy, anodised.
Spindle steel, case-hardened.
Spindle bearing maintenance-free.
Spindle steel, case-hardened.
Spindle bearing maintenance-free.
Version
Radial play of rotation axis < 0.015 mm.
Axial play of rotation axis < 0.02 mm.
Repeat accuracy < 0.05°.
Spindle self-locking.
Axial play of rotation axis < 0.02 mm.
Repeat accuracy < 0.05°.
Spindle self-locking.
Note
360° adjustment with no end stop.
10-graduation scale.
Transmission ratio:
21160-08 = 50:1
21160-12 = 55:1
21160-251 = 50:1
The rotary positioning stage can be easily configured to the required size using a modular design.
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 21160-08 and 21160-12 can be clamped against the rotary stage housing using rotary stage clamps 21161-11 and thus secured against accidental movement.
