  • What Is Break Away Torque?

    What is breakaway torque or as others call it, Residual Torque? Once torque has been applied to a joint, an audit function measures exactly how tight that fastener was torqued. Please note, due to surface conditions, joints can relax. So there can be changes in the clamping force between the time the torque was applied and the time that the ...

    Starting torque. The starting torque of a rolling bearing is defined as the frictional moment that must be overcome by the bearing to start rotating, at an ambient temperature of 20 to 30 °C (70 to 85 °F). Therefore, only the sliding frictional moment and the frictional moment of seals, if applied, are taken into consideration. M start = M sl ...
