Introduction of Good Cylindrical Roller Bearing
The rolling elements are radial rolling bearings with cylindrical rollers. The internal structure of good cylindrical Roller Bearing adopts rollers arranged in parallel, and spacers or spacers are installed between the rollers, which can prevent the inclination of the rollers or the friction between the rollers, and effectively prevent the increase of the rotational torque.
Best cylindrical rollers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the rib of the ring is small, which is suitable for high-speed rotation.
Features of High Quality Cylindrical Roller Bearings
1. The roller and the raceway are in line contact or trimmed line contact, and the radial bearing capacity is large, which is suitable for bearing heavy loads and impact loads.
2. The friction coefficient is small, suitable for high speed, and the limit speed is close to that of deep groove ball bearings.
3. N type and NU type can move axially, can adapt to the change of relative position between shaft and shell caused by thermal expansion or installation error, and can be used as free end support.
4. The processing requirements for the shaft or seat hole are relatively high. After the bearing is installed, the relative deflection of the outer ring axis should be strictly controlled to avoid contact stress concentration.
5. The inner ring or outer ring can be separated for easy installation and removal.
