1.2.8 Install a lock collar
Sealed ball bearings are held in position on many shafts with lock collars. The lock collar has an eccentric
counterbore. This counterbore engages the end of the bearing inner race when the bearing is assembled.
The lock collar is turned on the bearing to lock the assembly on the shaft. That assembly holds the shaft
tightly with a positive lock effect that increases with use. A set screw in the lock collar applies more lock
pressure.
Procedure
1.
Install the bearing (1), move the lock collar (2)
onto the shaft.
2.
Push the lock collar against the bearing inner
race (3).
3.
Turn the lock collar in the direction of the
shaft rotation until tightly engaged.
4.
To tighten the lock collar, put a punch in the
pin hole (5) and tap the punch with a
hammer.
NOTE:
Always tighten the lock collar in the
same direction of the shaft rotation.
5.
Tighten the set screw (4) to the correct
specification in the lock collar.
