Cheap NJ2317E Industrial high performance NJ2317M 85*180*60mm High stability cylindrical roller bearing supplier
Cylindrical roller bearing
Cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bear radial load. The friction between the rolling body and the rim of the ring is small, suitable for high-speed rotation. According to whether the ring has a guard, it can be divided into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. The bearing is a separable structure with inner and outer rings.
Cylindrical roller bearings with inner or outer rings without guards, whose inner and outer rings can move relative to each other in the axial direction, so they can be used as free-end bearings. One side of the inner ring and the outer ring has a double guard, and the other side of the ring has a single guard cylindrical roller bearing, which can bear a certain degree of axial load in one direction. Generally use steel plate stamping cage, or copper alloy car solid cage. But some use polyamide forming cages

characteristic
Cylindrical roller and raceway are in linear contact, the radial load capacity is large. Suitable for bearing heavy load and impact load, but also suitable for high-speed rotation.
Cylindrical roller bearing raceway and rolling body are geometric shape. After the improved design, it has a higher bearing capacity. The new structure design of the guard and roller end face not only improves the axial bearing capacity of the bearing, but also improves the lubrication conditions of the contact area between the roller end face and the guard, and improves the service performance of the bearing

characteristic
1. Roller and raceway for line contact or repair line contact, radial bearing capacity is large, suitable for bearing heavy load and impact load.
2. Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearings.
3. N type and NU type can move axially, can adapt to the change of the relative position of the shaft and the shell caused by thermal expansion or installation error, can be used as free end support.
4. The processing requirements of shaft or seat hole are higher, and the relative deflection of the outer ring axis after bearing installation should be strictly controlled, so as not to cause contact stress concentration.
5. Inner ring or outer ring can be separated, easy to install and disassemble
