What kind of bearing is a end face bearing?

End face bearings, also known as flat bearings, are composed of flat cage components with needle rollers, cylindrical rollers, or steel balls, and flat washers.

Flat bearings are divided into flat bearings with needle rollers and flat bearings with balls.

effect

The needle roller and cylindrical roller are held and guided by a flat cage.

When used with different series of DF flat bearing washers, many different combinations can be provided for the bearing configuration.

advantage

Due to the use of high-precision cylindrical rollers (needle rollers) to increase the contact length, this bearing can achieve high load capacity and high stiffness in a very small space.

Another advantage is that if the surfaces of adjacent parts are suitable as raceways, washers can be omitted, which can make the design compact. DF flat needle roller bearings and flat cylindrical roller bearings use cylindrical surfaces of needle and cylindrical rollers as modified surfaces, which can reduce edge stress and improve service life.
