High Load Capacity Cylindrical Roller Bearing Structure And Characteristics Of Use

What is Cylindrical roller bearings

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

Cylindrical roller and raceway line contact, radial load capacity is large. It is suitable for bearing heavy load and impact load as well as high speed rotation.

Cylindrical roller bearing raceways and rollers are geometrically shaped. After the improved design, it has a higher bearing capacity. The new structure design of the flange and the roller end face not only improves the axial bearing capacity of the bearing, but also improves the lubrication condition of the contact area between the roller end face and the flange, and improves the service performance of the bearing.

Application of Cylindrical roller bearings

Large and medium-sized motors, locomotives and rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, reduction boxes, rolling mills, vibrating screens and lifting and transport machinery.

High load capacity cylindrical roller bearing structure and characteristics of use

It is very difficult to maintain the speed accelerating engine of wind turbine installed in high place, so the life and reliability of the speed accelerating engine bearing are very high. In recent years, the wind turbine is becoming larger and larger. In order to reduce the load of the tower, it is attempted to make the generator cabin small and lightweight. Therefore, the demand for small and high load capacity bearings is further increased.

In order to meet this demand and develop high load capacity cylindrical roller bearings, because of the use of rolling body ring instead of cage, so do not destroy the rotation performance and increase the load capacity, the rated life reached more than 1.5 times of the original product.

Structure and characteristics of high load capacity cylindrical roller bearings: the new product is designed between the rollers made of resin ring, which can prevent the rollers from contacting each other. And on the separate rings, because the tension produced by the clutch and aggregation of the rollers does not work, the thickness can be changed, so the size and number of rollers can be increased.

Through the performance comparison between the new product and the original product, the new product's high-load capacity cylindrical roller bearing has the following advantages:

1.Long life

The size and number of rollers reach the best, so that the load capacity is increased, the rated life of the bearing is more than 1.5 times of the rated life of the original size of the bearing with the cage.

2. High speed

It is better to optimize the shape and guide method of the spacer to prevent the roller from contacting each other in the fully loaded roller bearing, so as to achieve the same allowable rotation speed and abrasion resistance as the bearing with the cage.

3. Operation

Even if the inner ring is removed without the roller falling off, the inner ring and outer ring components can be installed separately for easier installation on the machine.
