The type of needle bearing is an important torque index. Generally, the needle roller has lower low-speed torque. As we all know, lubricating grease lubricated by lubricating grease will have a lower torque at high speed, especially when groove lubricating grease is used. Low viscosity oil has higher torque than high viscosity oil.

The design of cylindrical roller bearing will also damage the torque. Lightweight metal and die plastic cages have the least torque at low and medium speeds. The torque of urea formaldehyde resin and calcined polyester cage is lower at high speed. Very low contact angle or axial side clearance value shows high torque. Due to geometric deviation of dovetail guide rail and steel ball of cylindrical roller bearing, the in-situ stress changes unevenly, which may lead to friction level. A high contact angle has a higher torque level due to the drag of the fitness movement in the contact area between the ball and the event.

The level of torque testing varies from manufacturer to manufacturer, and even the batch number of a manufacturer is different. There are three types of torque Rated current of cylindrical roller bearings, which are all based on the oil wetting test under light load.
