High Load P0 NJ2304E Cylindrical Roller Bearing SIZE 20x52x21mm

High Load P0 NJ2304E Cylindrical Roller Bearing SIZE 20x52x21mm

The BEARING capacity of NJ2304E is large, mainly bearing radial load.
The friction between rolling body and ring retaining edge is small, suitable for high speed rotation.
NTN NJ2304E bearings can be divided into single-row, double-row and multi-row cylindrical roller bearings according to the number of rolling body, and other different structures.
Different structure bearing is also shown in the design of the position of the edge.

1. The roller and the raceway are in line contact or off-line contact with large radial bearing capacity, which is suitable for bearing heavy load and impact load.
2. Low friction coefficient, suitable for high speed, limit speed close to deep groove ball bearing.
3. N type and NU type can be moved in axial direction, which can adapt to the change of relative position of shaft and shell caused by thermal expansion or installation error, and can be used as free end support.
4. The machining requirements for the shaft or seat hole are relatively high. After the bearing is installed, the relative deflection of the outer ring axis should be strictly controlled to avoid the concentration of contact stress.
5. The inner ring or outer ring can be separated for easy installation and disassembly.

6.NJ2304E bearing structure form

It is a separable bearing, easy to install and disassemble.
Cylindrical roller bearing can bear large radial load and is suitable for use in high-speed operation.
The Angle error (inclination) between the axis of the inner ring and the axis of the outer ring is very small, only 2 '~ 4'.
Therefore, the machining accuracy of the shaft and bearing pedestal is relatively high. Otherwise, uneven load or stress concentration is easy to occur at the contact part of raceway.
However, the stress concentration can be reduced by modifying the roller or raceway contact bus.
