* Consult Logan Clutch for applications that require lower actuation pressure or increased torque and rpm requirements or greater installation angle.
** Soft start feature may be required for engagement above machine idle rpm.
* Input drive flange bolt pattern are dimensioned to correlate with Lovejoy or Centa torsional coupling size 50.
|
Note: The torque capacity of the clutch is directly proportional to the operating pressure. Maintaining the lowest pressure possible to transfer the desired torque will enable the clutch to run cooler and extend the life span of the internal bearings.
The output end of the clutch (female spline/bore) is not capable of supporting any side load. Use overhung load adapters.Drive shaft alignment must be within 3 degrees. Maximum installation angle should be 7°.
