Roulement à rouleaux cylindriques

Cylindrical roller bearing
Cylindrical roller bearing:
1. Basic type: NU200; N300; NJ300; NF series
2. Brand: SKF NSK
3. Cage: Brass or steel
Basic types
Cylindrical roller bearings according to the type of wall to divide the different forms: NU-bearing outer ring has two ribs, no inner wall, N-bearing inner wall of two, with the outer ring wall
NU and the N-type cylindrical roller bearings for the floating terminal. They are bearing detachable for easy installation and removal of inner and outer rings can be used with tight. NJ-cylindrical roller bearing outer ring has two ribs, one inner wall, can withstand axial force in one direction. NUP type cylindrical roller bearings were fixed for the end of the two could take the direction of the axial force. There are two type of bearing outer wall, a fixed inner wall and a wall of activities. NJ-A cylindrical roller bearings and the angle of a circle composed of HJ-NUP similar to that of fixed-side bearings. Cylindrical roller bearings can be enhanced under big load, the basic design for 2E, 22E, 23E Series. Their roller is designed to be able to bear the largest burden.
Bearing Clearance
Single row cylindrical roller is bearings of the basic types of radial clearance for the ordinary level. According to the need to provide C3with the suffix bearings (radial clearance than an ordinary group of clearance) or with C4 bearing the suffix (radial clearance than C3).
For in
Cylindrical roller bearings in the amended Roller Raceway and the line of contact can reduce stress concentration. So as to allow a certain degree of tilt. Single row cylindrical roller bearings to allow the maximum deflection angle for the 4 °
Cage
Brass cage or steel cage
