Cylindrical Roller Bearing NJ306E

Cylindrical Roller Bearing NJ306E

1. Product details:

The cylindrical roller bearings of various structures are divided as per the different retaining edges. NU type cylindrical roller bearings have two retaining edges on the outer ring with no retained inner ring. N type cylindrical roller bearings have two retained inner rings with no retained outer ring. Both NU and N type’s cylindrical roller bearings are shifting bearings with separable inner and outer rings for easy dismounting. NJ type bearings have double retained outer rings with single retained inner ring. NF type bearings have double retained inner rings with single retained outer rings. They can bear the single directional axle force. NUP type cylindrical roller bearing is used as fixed bearing which can bear the alternative directional axial force. Bearings of this type have double retained outer ring with one retaining ring.

(7) International clearance codes: c2, c3, c4, c5

3. Features:

To distinguish from the common cylindrical roller bearings, the reinforced E cylindrical roller bearings are marked with the suffix E. This E type of bearings have the same main dimensions as the common bearings except the increased diameter, length, and numbered of the rollers. The load capacity is also enhanced accordingly. This type of bearings have big rational load. So as shown in Figure, when compared with the common bearings of the same shaft diameter, the bearing outer diameter should be reduced or the shaft diameter should be increased when the bearings with same outer diameter are used so that the rigidity of the shaft can be enhanced. Besides, the encircled of E type is different from the common bearings, so they are not inter-changeable.
