How To Reduce The Vibration Friction Problem Of thrust Cylindrical Roller Bearings

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.

How to reduce the vibration friction problem of thrust cylindrical roller bearings

1. Keep the bearing and its surrounding environment clean

Even if tiny dust invisible to the naked eye enters the bearing, it will increase the wear, vibration and noise of thrust cylindrical roller bearings. Bearing and its surrounding accessories should be kept clean, especially dust and dirt, tools and working environment must also be kept clean.

2. Use and install carefully

Strong stamping is not allowed, direct hammering of thrust cylindrical roller bearings is not allowed, and pressure transfer through the rolling body is not allowed.

3. Use appropriate and accurate installation tools

Use special tools as much as possible, and try to avoid things like cloth and staple fibers.

4. Prevent the corrosion of bearings

When taking bearings directly by hand, we should fully wash the sweat from our hands and coat them with high quality mineral oil before operation. In the rainy season and summer, we should pay special attention to rust prevention. However, under some special operating conditions, the life of bearings can be longer than that of traditional calculation, especially in the case of light load. These special operating conditions are the surface damage that can result from contaminants when the rolling surfaces (tracks and rolling parts) are effectively separated and limited by a lubricating film. In fact, under ideal conditions, so-called permanent bearing life is possible.
