Maintenance Of Double-row Self-aligning Roller Bearings After Use

What is Self-aligning roller bearings

The self-aligning roller bearing has a double row of rollers, and the outer ring has a common spherical raceway, and the inner ring has two raceways and is inclined to an Angle relative to the bearing axis. This ingenious structure enables it to have automatic self-aligning performance, so it is not susceptible to the influence of the Angle between the shaft and the bearing box seat on the error or shaft bending. It is suitable for the occasion of Angle error caused by the installation error or shaft deflection. The bearing can bear radial load as well as axial load for bidirectional use.

Characteristics of Self-aligning roller bearings

Mainly bear radial load, and can bear small axial load.The axial displacement of the shaft is limited within the clearance limit, and it has the performance of automatic self-altering. It can work normally under the condition that the relative inclination of the inner and outer parts is not large. It is suitable for the parts where the coaxiality of the supporting seat hole cannot be strictly guaranteed.

Application of Self-aligning roller bearings

Paper making machinery, reducer, railway vehicle axles, rolling mill gear box bearing block, rolling mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, various industrial reducer, vertical self-aligning bearing with belt seat.

Maintenance of double-row self-aligning roller bearings after use

Notes for the use of Self-aligning roller bearings are as follows:

Double row self-aligning roller bearing a move, the inner ring to take the outer ring of the raceway surface, because the rolling body is rolling contact, so the running track is the dark side, the running track attached to the raceway surface is not very, which can know the load premise, so under the bearing is removed the environment, what are the types of bearing seals. Please pay close attention to the running track of the raceway. If you carefully look at the running track, it will be obtained to bear radial load, to bear large axial load, to bear torque load, or to be on the bearing box without extreme rigidity inequality.

When the double-row self-aligning roller bearing is removed for inspection, the appearance of the bearing should be recorded by photography and other methods. In addition, it is necessary to confirm the amount of residual lubricant and sample the lubricant before cleaning the bearing.

1. The cleaning of double-row self-aligning roller bearing is divided into rough cleaning and fine cleaning, and the metal mesh frame can be placed at the bottom of the container in use.

2. When rough washing, use a brush to remove grease or adhesives in the oil. At this point, if the bearing is rotated in oil, pay attention to the damage to the rolling surface due to foreign bodies.

3. When fine washing, slowly rotate the double-row self-aligning roller bearing in oil, which must be carefully carried out.

The cleaning agent is usually neutral without water diesel oil or kerosene, according to the need sometimes also use warm lye, etc. Whatever cleaning agent you use, filter it frequently to keep it clean. Immediately after cleaning, coating anti-rust oil or anti-rust grease on the double-row self-aligning roller bearings.
