Installation Instruction

1) Connect rotation

Air cylinder and piston will be caused connect rotation by bearing, it can be use 3 pieces of stop grooves in 120°angle or auxiliary stop groove screw holes to fix or stop. Be careful, when they are stopped, cylinder shouldn’t be incline because of interference power, or it will influence clutch normal working.

2) Precaution when installation clutch onto shaft

It is better to use professional tool to inflate hollow shaft tube when install clutch onto shaft, don't hit cylinder or other easy wearing parts.

3) Belt pulley and gear installation

When install belt pulley or gear onto clutch driving cover, try to make sure radial force center of belt pulley or gear is align with two units of bearings loading center of driving cover. Excessive incline will influence clutch service life.

4) Bearing lubrication

The trust ball bearing should be lubricated periodically. The period is between 1 to 6 months depends on the working condition. The other bearings are sealed, there is no need to supply.

5) Avoid high load working

It is better to use double or triple safety factor when choose modell, overload usage will reduce clutch service life. When usage frequency exceed 2-3 times per minute, we suggest use larger safety factor, the allowable maximum usage frequency is 6 times per minute.
