Cylindrical Roller Bearing Rn
Cylindrical roller bearing is a kind of bearing with the simplest structure. The inner wheel and outer wheel are in line contact with the roller. It has a large radial load capacity. Cylindrical roller bearings are separated type, easy to install and disassemble.
RN type bearing without outer ring, inner ring with double guard edge. For parts with limited radial dimensions, the journal or shell hole surface is directly used as the raceway surface, and the raceway surface hardness, machining accuracy and surface quality should be similar to the raceway of the ring.
Steel plate stamping cage is generally used for cylindrical roller bearings, brass turning cage is used for larger size or for high-speed rotation, double or four row cylindrical roller bearings are used to extend the service life.
