Mounting to customer shaft with shaft shoulder

If a shaft with shaft shoulder is used, the shaft shoulder must have a minimum height. For the dimensions for the shaft diameter at the shaft shoulder and at the shaft at the area of hollow shaft, refer to the following table.

Clean the customer shaft and the inside of the hollow shaft. Make sure that all grease and oil residues are removed.

Push the bushing onto the customer shaft up to the shaft shoulder.

Apply NOCO-Paste onto the bushing and spread it thoroughly.

Push the gear unit [5] onto the customer shaft up to the stop.

Fasten the gear unit on the mounting surface (do not tighten the screws).
CAUTION! The shrink disk can slip when not tightened. Potential risk of crushing due to falling parts. Secure the shrink disk against slipping.NOTICE! Tightening the locking screws without first installing a shaft may result in the hollow shaft being deformed. Possible damage to property. Never tighten the screws without the shaft installed.Make sure that all locking screws are loosened and slide the shrink disk [6] onto the hollow shaft [2].

Position the inner ring [6c] of the shrink disk to dimension A.

Slide the counter bushing [7] onto the customer shaft and into the hollow shaft [2].

Tap lightly on the flange of the counter bushing [7] to ensure that the bushing is fitted securely in the hollow shaft.

Make sure that the conical bushing [7] is pushed into the shaft until there is no play between the customer's shaft [1], bushing [7], and hollow shaft.

Tighten the locking screws [6a] of the shrink disk only manually. Align the taper (outer ring) [6b] parallel to the taper bushing (inner ring) [6c].

INFORMATION

If the taper (outer ring) and the taper bushing (inner ring) cannot be aligned on the face that holds the screws, disassemble the shrink disk again and carefully clean/lubricate it sufficiently.

Tighten the locking screws clockwise (not in diametrically opposite sequence) by a quarter turn each. Work around the ring in several stages, evenly tightening the locking screws [10] by a quarter turn until the taper (outer ring) [9a] and the taper bushing (inner ring) [6c] align on the face that holds the screws as is shown in the illustration below.
The remaining gap between bushing and hollow shaft end, as well as mating bushing and hollow shaft end must be > 0 mm.

Tighten the retaining screws of the gear unit with the specified tightening torque. For the tightening torque, refer to the operating instructions of the gear unit.

[6a]	Locking screws	[L1]	Delivery state (pre-assembled)
[6b]	Outer ring	[L2]	Completely assembled (ready for operation)
[6c]	Inner ring
