NACHI Roller Bearing Silinder Seri NJ

- Designs and Configurations
NACHI Cylindrical Roller Bearings are produced in a wide variety of designs and configurations.
- Conventional Design
Cylindrical Roller Bearings of conventional design are available in 10 configurations as shown in Fig. 1. Configurations N, NU, NN and NNU will not sustain axial loading. These configurations must be used as the float end bearing. Configurations NF, NJ, NUH are designed with the capability of sustaining axial loading in one direction. Configuration NUH is basically an NU bearing with an addition of a guide ring (an “L” ring).'The NUH dimensional data is the same as theNH bearing configuration. Configuration NF, NJ, and NUH can sustain axial loading in one direction. Configuration NH, NP, and NUP have bidirectional thrust load-carrying-capability.
- The suffix of the bearing number indicates:
E: high capacity
G: polyamide cage
- The bearing with polyamide cage should
be used at less than 120˚C operating temperature.
- Interchangeable Bearings
Interchangeable cylindrical roller bearing means that a separable ring can be replaced by another ring of the bearing with the same bearing number without impairing the function of the bearing
- Radial Internal Clearance
The initial radial internal clearance of the bearing should be determined for optimal bearing operation
