INA F-207407 Cylindrical Roller Bearing F 207407 Hydraulic Pump Bearing F-207407 65x120x33mm

1. Bearing Specifications :

Cylindrical roller and raceway are linear contact bearings.Large load capacity, mainly bearing radial load.The friction between the rolling body and the sleeve is small and is suitable for high-speed rotation.It can be divided into NU, NJ, NUP, N, NF and other single-row cylindrical roller bearings, as well as dual-row cylindrical roller bearings such as NNU and NN, depending on whether the sleeve has side or not.The bearing is a separable structure of inner ring and outer ring.

2. cylindrical roller bearing Andvages:

1. The roller is in line contact with the raceway or in line contact with the downline. The radial bearing capacity is large, which is suitable for bearing heavy load and impact load.

2. Low friction coefficient, suitable for high speed, the ultimate speed is close to deep groove ball bearing.

3. N type and NU type can move in the axial direction, which can adapt to the change of the relative position between the axis and the shell caused by thermal expansion or installation error, and can be used as free end support.

4. High processing requirements are required for shaft or pedestal holes. After bearing installation, the relative deviation of outer ring axis should be strictly controlled to avoid contact stress concentration.

5. The inner or outer rings can be separated to facilitate installation and disassembly.
