Needle Roller Bearings
Needle roller bearings are bearings that use small cylindrical rollers. These rollers are used to reduce the friction of a rotating surface. The cylindrical rollers that have small diameters offer a higher load-carrying capacity. Needle roller bearings are the smallest and lightest of the roller bearing family which is best for reduced space and weight. The bearings are often used in the automotive industry, lawn and garden equipment, printing machines, and machine tools. These bearings are often compared to ball bearings except needle roller bearings have a large surface area that is in touch with the bearing raceway. The bearings can combine maximum load capacity and low cost. Needle roller bearings are able to hold a larger, more rigid shaft in a given application. They have great rolling features within a small cross-section and are often classified as either radial or thrust depending on the direction of the load. The following are some key considerations and benefits of needle roller bearings:
- Easy lubrication
- Bear both radial and axial loads
- Long service life
- Low friction
- Increase performance capability
- Have the ability to use mating surfaces as inner or outer raceways, or both
The size and width of needle roller bearings vary according to their use and application.
