Features of cylindrical roller bearings

wallpapers Tech 2020-08-27
The cylindrical roller bearings is in line contact with the raceway, and the radial load capacity is large. It is not only suitable for bearings heavy load and impact load, but also suitable for high-speed rotation.
The raceways and rolling elements of cylindrical roller bearings are geometrically shaped. After the improved design, it has a higher load carrying capacity. The new structural design of ribs and roller end faces not only improves the axial load carrying capacity of the bearing, but also improves the lubrication conditions of the contact area between the roller end face and the rib. The performance of the bearing.
1. Roller and raceway are in line contact or repaired offline contact, with large radial load capacity, suitable for bearing heavy load and impact load.
2. The friction coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing.
3. The N type and NU type can move axially, can adapt to the change of the relative position between the shaft and the housing caused by thermal expansion or installation error, and can be used as a free end support.
4. The processing requirements for the shaft or seat hole are high, and the relative deflection of the outer ring axis after the bearing is installed must be strictly controlled to avoid contact stress concentration.
5. The inner ring or outer ring can be separated for easy installation and disassembly.
