Cylindrical Roller Bearings
Cylindrical roller bearings ( also called CRB in short) are a kind of radial rolling bearings with cylindrical rollers. The rollers are lined in parallel shapes, in between the rollers are cages that are able to avoid the leaning of roller or friction between rollers. In consequence, the rotating torque is also avoided. The contact between the cylindrical rollers and the raceways is linear contact. In general, cylindrical roller bearings adopt pressed steel cages or machined brass cages. This design is employed by leading manufacturers like ZWA Bearings, one of the leading China cylindrical roller bearing manufacturers.
Types of cylindrical roller bearings
Cylindrical roller bearings can be classified in several types based on different index. Based on the row of rollers, cylindrical roller bearings can be divided into single row cylindrical roller bearing, double row cylindrical roller bearing and four row cylindrical roller bearing. Based on the ribs of the rings, cylindrical roller bearings can be divided into NU, NJ, NUP, N, NF, NNU, NN etc types. For this classification, the inner and outer ring are separable. ZWA Bearings manufactures types of cylindrical roller bearings to meet customers' demand in diferent industries like mining, steel making, etc.
Single Row Cylindrical Roller Bearing
Single row cylindrical roller bearings with cages are part of radial roller bearings. Compared with the ball bearings’ balls, the rollers have a bigger contact to the roller axle.
Double Row Cylindrical Roller Bearing
The rollers of double row cylindrical roller bearing are crossing arranged. While rotating, the wave ratio is one time higher than single-row cylindrical roller bearings.
Four Row Cylindrical Roller Bearing
Four-row cylindrical roller bearings are kind of separable bearings. The rings and roller components are easily separable.
Full Complement Cylindrical Roller Bearings
Full complement cylindrical roller bearing is a kind of cylindrical roller bearing designed without cages. In this design, the number of rollers are the biggest in all the bearings types.
Cylindrical Roller Thrust Bearing
Cylindrical roller thrust bearings consist of rollers, cage components, shaft ring and housing ring. Those components are separable for efficient and convenient operations.
