Torque testing 

Most installation specifications require testing for maximum "no load rotational breakaway torque" after the bearing is installed and staked. 

 

We stock dial indicating torque wrenches and torque test adaptors for bearings from .187 inches I.D. to 1.000 inch I.D. Other sizes are available with special order.

These wrenches feature a large easy to read dial with an indicator needle to record the highest torque before the breakaway occurs. Accuracy is +/- 4% of actual indicated torque and are calibrated in both CW and CCW rotation. Torque test adaptors are manufactured from hardened and ground alloy steel. The adaptors assure that torque readings are on centerline and accurate. It is suggested that "self-lubricated" (TFE) type bearings be misaligned back and forth and rotated a few times before testing. This movement will guard against false readings and result in more accurate inspection.
