Installation and Usage
1. For installation, insert the clutch
into the hub bore of a pulley, a
gear, or a torque arm and screw
the bolts (high tension) into the
tapped holes in the end face of
the clutch. See illustration on the
right.
2. A press fit is required for MX
Series clutches for indexing
applications, but do not exceed
0.025 mm when press fitting.
3. Adjust the side of the key to fit
the keyway tightly, but allow a
clearance between the top of
key and keyway.
4. When mounting the clutch on a
shaft, apply pressure to the
clutch inner race end, but never
to the outer race.
5. Proper selection of the Cam
Clutch provides accurate
indexing performance. A braking
device and a backstopping
device may also be required for
more accurate performance.
6. The tolerance of the hub bore
should be H6 or H7.
