What is cylindrical roller bearing
The cylindrical roller and the raceway are linear contact bearings. Large load capacity, mainly bear radial load. The friction between the rolling body and the ring edge is small, which is suitable for high speed rotation. According to the ring with or without flange, it can be divided into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. The bearing is a structure with separable inner and outer rings.
Characteristics of cylindrical roller bearings
1. Roller and raceway for line contact or repair line 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. Type N and NU can be moved axially, which 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 high. The relative deviation of the outer ring axis should be strictly controlled after the installation of the bearing to avoid the concentration of contact stress.
5. The inner ring or outer ring can be separated for easy installation and disassembly of tapered roller bearing applications
Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
Application of a variety of cylindrical roller bearings
Cylindrical roller bearings can be divided into single row, double row and multi-row cylindrical roller bearings and other different structures according to the different number of rows of rollers installed.
Among them, the commonly used cylindrical roller bearings have the following forms:
1.Single row cylindrical roller bearings: single row cylindrical roller bearings are separable bearings, easy to install and disassemble, two rings can be used tight match, the contact line between the modified roller and the raceway can reduce stress concentration.
2.Double row cylindrical roller bearings: Double row cylindrical roller bearings belong to swimming bearings, and their separability makes installation and disassembly very convenient. Both rings can be fitted tightly. Double-row cylindrical roller bearings allow almost no inclination.
3.Four row cylindrical roller bearings: this kind of bearings are mainly used in cold and hot rolling mills, blank cutting machines and other rolling machine machinery, bearing is separated structure, bearing ring and rolling body assembly can be easily separated, therefore, bearing cleaning, inspection, installation and disassembly are very convenient.
