8.1.3 Mounting with locking series B, S
Only standard groups and ATEX 3G/3D. Gear reducers may be fitted with a locking set to lock the hollow shaft on the
driven shaft. For fitting the locking unit proceed as follows:
Undo the locking set screws, in sequence and gradually;
Degrease with care the surfaces of the hollow shaft and of the machine pin to couple;
Check that the locking shaft diameter is correct (h7);
Mount the locking unit on the gear reducer hollow shaft, lubricating beforehand the outer surface of the hollow shaft;
Tighten slightly a first set of three screws placed at approx. 120° as shown in the figure;
Tighten the locking unit gradually and uniformly with a torque wrench up to the toque indicated in the table below,
with continuous sequence (not crossed) making ¼ of a turn at a time until reaching the prescribed tightening torque;
Keep applying the torque for 1 or 2 further steps and at the end check the bolt tightening torque;
In case of stressful working cycles with frequent motion inversions, check again, after a few hours of operation, the
screws' tightening torque.

For disassembling the locking unit proceed as follows:
Clean all the oxidized areas. Loosen one fixing screw after the other only by rotating them of ½ a turn at a time, with
continuous sequence (not crossed), until the locking unit can be moved on the hollow shaft. Remove the customer's shaft
or gear reducer.
In any case, refer to the installation manual of the part to be assembled.
In case of safety problems, unfavourable mounting positions (shaft pointing down), vibration or external
axial loads, arrange suitable devices to prevent the shaft from sliding out!
Do not remove completely the fixing screws before releasing the locking rings. Risk of serious injury!
