Cylindrical Roller Bearing

Cylindrical roller bearing features The characteristics of cylindrical roller bearings mainly include: 12 Large radial bearing capacity. Since the roller is in line contact with the raceway, this design enables the bearing to withstand a large radial load, which is suitable for heavy loads and impact loads. Low friction coefficient, suitable for high-speed operation. The friction resistance of cylindrical roller bearings is small, which makes it suitable for high speed occasions, and its limit speed is close to that of deep groove ball bearings. The inner and outer rings can be separated. This design makes the installation and disassembly of the bearing more convenient, so that the user can replace or repair the bearing in the later maintenance. Can withstand large radial loads. Cylindrical roller bearings are usually used to bear radial loads, but some types, such as cylindrical roller bearings with a single inner rim and a flat retaining ring, can also bear smaller two-way axial loads. Simple structure, easy to use.

Cylindrical roller bearing is a commonly used rolling bearing with simple structure and convenient use. It is suitable for high-speed rotation of vibration equipment. The cylindrical roller bearing can be in linear contact with the raceway, so the sliding friction is small when the rolling body moves with the outer flange, which is suitable for the high-speed rotation of vibration equipment. It can adapt to changes in the relative position of the shaft and the housing caused by thermal expansion or installation errors. Some types such as N-type and NU type cylindrical roller bearings can move axially, can adapt to the change of the relative position of the shaft and the housing caused by thermal expansion or installation error, and can be used as free end support. In addition, cylindrical roller bearings have higher processing requirements for shafts or seat holes, and the relative deviation of the outer ring axis after bearing installation should be strictly controlled to avoid contact stress concentration.
