Cylindrical Roller Bearings
Rolling body is a cylindrical roller rolling bearing to the heart. Cylindrical Roller Bearings The internal structure of the roller was 90 ° perpendicular cross arrangement (which is also a cross roller bearing origin of the name), equipped with a space between the roller cage or spacers can be prevented inclined roller or rollers mutual grinding between police, effectively preventing the increase of rotational torque.

Bearing Features
1. roller and the raceway is in line contact or repair offline contacts, radial load capacity, suitable to withstand heavy load and shock load.
2. The friction coefficient is small, suitable for high-speed, speed close to the deep groove ball bearings.
3. N type and NU type can move axially, able to adapt due to thermal expansion or installation error of shaft and housing caused by the relative change in position can be used for supporting the free end.
4. shaft or housing bore machining are higher, install the rear bearing outer ring axis relative deflection should be strictly controlled to avoid contact stress concentration.
5. The inner or outer detachable, easy installation and removal.

Product Features

Cylindrical roller line contact with the raceway, large radial load capacity. Both to withstand heavy load and impact load, but also for high-speed rotation.
Cylindrical roller bearings raceways and rolling lanes geometry. After the improved design, with high load carrying capacity, the new design ribs and roller end, not only improves the axial bearing capacity, while improving the roller end wall contact areas and lubriexcavatorion conditions, improved performance of the bearing.
