Characteristics of needle rollers

Low friction: Due to the principle of rolling friction, needle roller bearings have less friction and high efficiency than sliding bearings.

High precision: Some high-precision needle rollers can be used in high-speed and precision equipment.


When choosing needle rollers, the following factors need to be considered:

Load requirements: Choose the appropriate specifications according to the load size required.

Speed requirements: When running at high speed, choose rollers made of materials that are suitable for high speed.

Temperature and environment: Choose appropriate materials and sealing methods according to the temperature and pollution conditions of the working environment.

Lubrication: Reasonable lubrication can reduce friction and extend the service life of the bearing.
