WARNING
CAUTION
Notice that although categorized under "CAUTION", subjects discussed may lead to serious results depending on the situation.
Make sure turning forces are not applied to Cam Clutch or turning shaft of the equipment when conducting inspection or maintenance.

Pay special attention to the back stopping application to prevent accidents.
 Frequent starting and stopping will apply excessive force on the mounting. Verify mounting strength.
 Inaccurate installation and mounting, various load conditions, wear and tear of parts, and life expectancy can all affect the performance
of a Cam Clutch. Inspect and maintain periodically and install a safety devise on your equipment.

■ Installation

1. 200 series Cam clutch is shaft mounted, so the shaft on which the clutch is mounted must be hardened
to Rc56-60 and 1.5 mm case depth after grinding.
Grind to 1.5S 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 6200 type bearings (B205 = 6205, B208 = 6208).
Bore tolerance of the housing in which the clutch is assembled should be within the table below.
5. For indexing, oil lubrication is recommended.
6. Concentricity of the housing bore and shaft should be within 0.05mm TIR.
7. Key profile should be in accordance with JIS B1301-1959.
