Access Plug
(Item 14)
Clamping Collar
(Item 7)
Output Shaft, Female End
(Item 1)
MOUNTED ON THE SHAFT END OF A MOTOR
NOTE: Refer to Figures 1, 2 & 3.
1. Place the Clamping Collar (Item 7) on the input (female)
end of the brake shaft. Finger tighten the cap screw until
the Collar is nearly snug. Then slide the Collar down
the Shaft until it is firmly against the shaft step.
NOTE: Some Clamp Collars require two cap screws to
provide necessary clamp load.
2. Remove the Access Plugs (Item 14) from the Input
Flange (Item 10). Rotate the Clamping Collar (Item
7) until the cap screw is lined up with the access
hole. Then insert an Allen driver or a T-handle wrench
through and engage the head of the cap screw. Leave
this driver or wrench in place while you perform the
next two steps.
CAUTION: Do not lubricate either the Clamping Collar
or the Shaft. Any lubricant on the contact surfaces could
result in torque transfer failure. If necessary, clean the
Shaft with a non-petroleum based solvent, such as
isopropyl alcohol, and wipe dry before assembly.
3. Slide the Motor Shaft into the input (female) end of the
Output Shaft (Item 1) until the Flanges of the Motor
and Brake come together.
4. Using four customer-supplied Socket Head Cap
Screws (See Table 2), bolt the Flanges together.
Tighten the cap screws evenly to the recommended
torques listed in Table 2 (Page 6).
5. Using the Allen driver or wrench used in Step 2, tighten
the cap screws in the Clamping Collar (Item 7) to the
recommended torque listed in Table 1 (Page 6).
CAUTION: Under tightening the Collar may cause
slippage between the motor and the Brake. This can
cause damage to the System, Motor and/or Brake.
6. Reinstall the Access Plugs (Item 14) into the access
holes on the Input Flange (Item 10).
7. Attach the Gear Reducer or the load to the Brake
Shaft.
