NTN Bearing Customized Bearing Cylindrical Roller Bearing N244

Single row cylindrical roller bearing is usually only subject to radial force, compared with the ball bearing of the same size, the radial bearing capacity is increased by 1.5-3 times, good rigidity, impact resistance, it is especially suitable for rigid support, and support the short shaft, heat elongation caused by axial displacement of the shaft and the installation and disassembly of the machine accessories need separation type bearing.

The rolling body is the centripetal rolling bearing of cylindrical roller. The inner structure of cylindrical roller bearing adopts rollers to be arranged in parallel, and there is a spacer or isolation block between rollers, which can prevent the tilt of rollers or friction between rollers, and effectively prevent the increase of rotating torque. Cylindrical roller and raceway line contact, radial load capacity. Suitable for bearing heavy load and impact load as well as high speed rotation.

Characteristics ：

1. Roller and raceway are in line contact or downline contact, radial bearing capacity is large, suitable for bearing heavy load and impact load.
2. Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearings.
3. The processing requirements for shafts or seat holes are high. After bearing installation, the relative deviation of the outer ring axis should be strictly controlled to avoid contact stress concentration.
4. The inner ring or outer ring can be separated, easy to install and disassemble.
