what is collar friction torque?

Collar Friction Torque is the additional torque required to account for the friction between Collar and Load. The presence of collar increases the friction torque. A thrust collar bearing must be employed between the rotating and stationary members in order to carry the axial component. Coefficients of friction around 0.1 to 0.2 may be expected for common materials under conditions of ordinary service and lubrication.
