Industry Product Tested Test Type

'Torque to turn' is what it takes to overcome friction and inertia in a rotating system.

Bearing assemblies, and shafts held in bearings, are typically tested for breakaway torque and running torque.

Breakaway torque is the turning force required to initiate rotation (similar to static friction), and running torque is the turning force required to keep a system in rotation (similar to kinetic friction).

This will be proportional to the mass being rotated and its moment of inertia. By using a programmable torque tester to record the properties of torque vs angular rotation, a complete signature can be obtained to indicate lack of concentricity, ‘chattering’ and other potential problems.
