Cylindrical roller bearing: here is the TIMKEN cylindrical roller bearing torque calculation formula of the coefficient depends on the bearing series, and are listed in the table below: M = f1 to decide F with dm + 10 -

Torque calculation formula of coefficient of bearing series f0f1 type size.
Torque rotary torque -
M bearing rotation resistance depends on the load, speed, lubrication condition and the characteristics of bearing inner.
The following formula can be rotated to approximate calculation bearing torque.
The formula is suitable for the lubrication of bearings.
For bearing grease or oil mist lubrication, torque are generally lower, while fat also depends on the amount of grease lubrication of torque and viscosity.
In addition, the formula is based on the assumption of running-in period bearing rotation torque has been stabilized.
Lubrication is to reduce the friction of the bearing, you need to use the lubrication: • minimized due to the rolling element and raceway by the load deformation occurred as the rotational resistance, minimize the rolling element and raceway and maintains the sliding friction between the heat transfer (
Use the oil lubrication)
, corrosion resistance, the use of grease lubrication, prevent pollutants into TIMKEN lubrication and sealing.
