Generally speaking, bearing blocks can be divided into outer spherical bearing blocks, integral bearing blocks, split bearing blocks, split vertical bearing blocks, rolling bearing blocks, sliding bearing blocks, bearing blocks with flanges, etc.

1. According to the different appearance of the outer spherical bearing seat, it can be divided into circular seat (C seat), square seat (F seat), vertical seat (P seat), suspended seat (FA seat), diamond seat (FL seat), convex circular seat (FC seat), convex square seat (FS seat), and blind hole seat (PA seat).

2. Some vertical bearing blocks can be subdivided into: SNL vertical bearing blocks, large and medium-sized SNL bearing blocks, SDG vertical bearing blocks, SONL vertical bearing blocks, SAF vertical bearing blocks, and SDAF vertical bearing blocks.

3. Integral bearing blocks can be subdivided into SBD vertical bearing blocks, TVN vertical bearing blocks, and TN vertical bearing blocks.

Wear issues

Wear is a more common problem with bearing blocks, and bearing block wear often occurs.

Repair method

The traditional method generally uses machining after spray welding to carry out repairs, while spray welding can cause high temperatures on the surface of the components. The manufacturer of the rolling bearing retainer sleeve causes deformation or cracks in the components, and obtaining specifications based on machining results in a significant increase in shutdown time. The use of polymer composite materials for on-site repair is not limited in terms of spray damage and repair thickness. The wear resistance of the product and the tolerance that metal materials do not have ensure 100% contact and coordination between the repaired parts, reduce the impact vibration of machinery and equipment, and prevent the probability of wear. Methods for on-site repair and prevention of machining.

Repair process

Generally, only four steps are required:

1. For surface treatment, it is necessary to repair the surface of the bearing seat to remove oil stains and moisture;

2. Blending repair materials;

3. Apply material evenly to the repaired part of the bearing seat, filling it firmly;

4. Wait for the material to solidify, and properly heat the material surface to accelerate the material solidification.

General rolling bearing housing wear can be repaired within 3-6 hours. The actual operation is simple and easy to learn, without unique machine equipment and professional training. Compared to laser welding, cold welding, and other technical savings, the cost is only 1/5-1/10 of the general repair cost. On-site repair also reduces equipment maintenance time and transportation costs.
