TSUBAKI EMERSON BACKSTOP CAM CLUTCHES BSEU & BS SERIES

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

Cam Clutch installation.

2.DIN6885.1keyway is standard.

3.Before installation, verify that the direction of rotation of the

inner race of the Cam Clutch (shwon 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 dependingo n the

number of shaft revolution. Further, if the number of shaft

revolutions is low, a higher ambient operational

temperature range is allowable.
