Clamp Screw / Tightening Torque Table
8. After positioning the coupling to the optimal shaft-hub engagement,
tighten the clamp screws to the specified torque value above. A
calibrated torque wrench is recommended for this operation.
The ServoClass
®
Coupling is now ready for operation.
Please contact the factory with any questions.
*NOTE: Aligning the shafts as closely as possible at the time of initial installation will allow the coupling extra
capacity for misalignments and loads which will occur during operation over the life of the connected equipment.
Installing and operating the coupling at higher degrees of misalignment is possible (see catalog ratings), but will
generally reduce the life of the coupling.
*NOTE: Rotating equipment is potentially dangerous and should be properly guarded. The user should follow all
applicable safety codes and provide a suitable guard.
