NACHI Roller Bearing Silinder Double Row NN3007M2K C9NA P4 1pc

- Designs and Confi gurations
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 confi gurations as shown in Fig. 1. Confi gurations N, NU, NN and NNU will not sustain axial loading. These configurations must be used as the fl oat end bearing. Configurations NF, NJ, NUH are designed with the capability of sustaining axial loading in one direction. Confi guration 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 confi guration. Confi guration NF, NJ, and NUH can sustain axial loading in one direction. Configuration NH, NP, and NUP have bidirectional thrust load-carrying-capability.

- The suffi x 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
