Wheel Hub Bearing Ring Turning Line

Wheel Hub Bearing Ring Turning Line

The rolling body is the centripetal rolling bearing of cylindrical roller. The internal structure of cylindrical roller bearing adopts rollers with 90° vertical cross arrangement (which is also the name of cross roller bearing). 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.
Features:
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. N type and NU type can be moved in axial direction, can adapt to the change of the relative position between the shaft and the shell caused by thermal expansion or installation error, can be used as free end support.
4. 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.
5. The inner ring or outer ring can be separated, easy to install and disassemble.
USES:
Large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, reduction boxes, rolling mills, vibrating screens and lifting and transportation machinery, etc.
