Installation and Usage
1. The bores of the pulley,
sprocket, etc., should have a
tolerance of H6 or H7.
2. Built in roller type bearing, due
to the structure of cam and
roller.
3. When installing the Cam Clutch
on the shaft, press the clutch
inner race slightly.
4. Never apply thrust loads to the
Cam Clutch. Other devices
should be provided to take up
thrust loads applied to the Cam
Clutch.
5. In case of large radial loads
applied to the Cam Clutch like
installing with pulley, another
bearing should be prepared so
that the point of the loads can
be hanged on the bearing.
6. Key should be in accordance
with ISO R773 (DIN 6885.1).
Note that the keyway
dimensions of outer race is not
in accordance with the keyway
dimensions which mentioned in
ISO R773 (DIN 6885.1).
7. See “Information for lubrication
and maintenance” on page 79.
8. In case of using the Cam Clutch
in a dusty atmosphere, or
preventing the Cam Clutch from
grease leakage, MDEU-2GD
(Cam Clutch with dust seal type)
is available as option.
Note that the maximum
overrunning speed of Cam
Clutch with dust seal type is
approximately 80% compared
with that of the standard model.
