Several Manifestations Of Self-aligning Roller Bearing Damage

What is Self-aligning ball 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 ball 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 ball 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.

Several manifestations of self-aligning roller bearing damage

1.The cavitation

Cavitation of self-aligning roller bearings is a form of surface damage caused by the contact and relative movement between solid surface and liquid surface. When the lubricating oil in the oil film of low pressure area, oil will form bubbles, the bubbles movement to high, the pressure under the action of air bubble breaking, the breaking of instant impact and high temperature, solid surface under the effect of the impact of repeated, material fatigue peeling, the friction surface appear small pits, and then developed into the cavernous scars. Cavitation often occurs in heavy load, high speed, and large variation of load and speed sliding bearings.

2. Fluid erosion

Fluid erosion of self-aligning roller bearings refers to fluid erosion caused by fluid intense impact on the solid surface, which causes spot-shaped scars on the solid surface. The surface of this damage is smooth.

3. Electrical erosion

The electric erosion of self-aligning roller bearings refers to the electric spark generated between the friction surfaces of bearings due to electrical leakage, which causes spotlike scars on the friction surfaces. Its characteristic is that the damage reciprocates on the surface of the hard journal.

The price of Self-aligning ball bearings
