Maintenance
7.1 Servo spindle motors EZS/EZM
Axial angular ball bearings are installed on the A-side in the
EZS and EZM motors that directly absorb the threaded
spindle forces. These axial angular ball bearings are greased
with lithium soap grease GA28 at the factory. Under certain
application conditions, for example after a prolonged
downtime or for high humidity, relubrication may be required.
Mineral-based grease is suitable for relubrication, for
example Arcanol Multitop.
Protect the threaded spindle against dirt.

10 Disposal
This product contains recyclable materials. Observe local
applicable regulations for disposal.
Mount the threaded spindle on the EZS motor:
1. Degrease the threaded spindle in the area where it
comes into contact with the clamping unit.
2. Insert the threaded spindle through the clamping set in
the hole of the motor shaft.
3. The wrench size and the tightening torque that
corresponds to the size of your EZS motor can be found
in the table Tab. 5-1:
4. Tighten the hexagonal screws of the clamping unit
successively in several tightening sequences (approx. 1/
4 revolution per sequence) properly with a torque
wrench until all of them are tightened to the prescribed
tightening torque. Make sure that both spring washers lie
parallel to each other (maximum permitted deviation 0.2
mm).
