Installation and usage for BSEU series

1. We recommend using a shaft tolerance of h7 or h8

for Cam Clutch installation.

2. ISO R773 (DIN6885.1) keyway is standard.

3. Before installation, verify that the direction of rotation

of the inner race of the Cam Clutch (shown by the

arrow on the inner race) is the same as the direction

of rotation of the conveyor.

4. When inserting the Cam Clutch on the shaft, apply

pressure only on the surface of the inner race with a

soft hammer. Never strike the Cam Clutch with a

steel hammer or apply unnecessary impact loads.

5. Always use a parallel key for installation onto the

shaft and then fix the Cam Clutch to the shaft with

the end plate. Never use a tapered key. Allow for a

clearance between the top of the clutch keyway

and the top of the key for pressure ventilation. A

pressure ventilation hole is provided on the keyway

of the clutch’s inner race.

6. Use the frame or a pin to eliminate outer race

rotation.

7. Set a 0.5 mm degree clearance between the torque

arm and the frame (torque arm stopper) or the long

slit in the torque arm and the pin. If the torque arm

is rigidly mounted, it will apply a load to the Cam

Clutch which may eventually damage it.

8. The Cam Clutch is pre-packed with low temperature

grease before shipment and is ready for installation

and operation. No lubrication maintenance is

required. The ambient operational temperature

range is –40° to 50°C. However, the maximum

temperature should be determined depending on

the number of shaft revolutions. Further, if the

number of shaft revolutions is low, a higher ambient

operational temperature range is allowable. Consult

with Tsubaki for more details.
