Surface bearing effect and feature
The rollers and cylindrical rollers are held and guided by a flat cage.
When used with DF flat bearing gaskets of different series, a number of different combinations of bearing configurations can be provided.
The use of high precision cylindrical roller (needle roller) increases the contact length, so that the bearing can obtain high load capacity and high stiffness in small space.
Another advantage is that if the surface of adjacent parts is suitable for the raceway surface, the gasket can be omitted and the design can be compact. The cylindrical surface of DF plain needle roller bearing and cylindrical roller bearing adopts the modified surface, which can reduce the edge stress and improve the service life.
