Installation and Usage
1. 200 Series Cam Clutch is shaft
mounted, so the shaft on which
the clutch is mounted must be
hardened to Rc 56-60 and 1.5 mm
case depth after grinding. Grind to
1.5S (16micro-inch) finish. The
taper of this shaft should not
exceed 0.01 mm per 50mm.
2. For installation of the clutch,
mount the clutch with bearings
at both sides or on one side in
order to obtain concentricity
between the shaft and the clutch
outer race and to take up radial
or thrust loads which may work
on the outer race or the shaft.
See the installation example.
3. The clutch should be mounted
on the shaft by rotating it in the
direction marked by the arrow
shown on the clutch plate. Do
not apply shock to the clutch by
hammering.
4. The clutches have the same
outside diameters as the
bearings shown in the table
above. Bore tolerance of the
housing in which the clutch is
assembled should be within the
range shown in the table below.
5. For indexing, oil lubrication is
recommended.
6. Concentricity of the housing
bore and shaft should be within
0.05 mm.
7. Key profile should be in
accordance with JIS B1301-1959.
