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, flanged bearing blocks, etc.

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

2. Some vertical bearing blocks can be subdivided into: SNL vertical bearing blocks, large 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 the most common problem of bearing blocks, and bearing block wear often occurs.

Repair method

The traditional method is generally to repair by machining after surfacing, which can cause the surface of the component to reach a very high temperature. The manufacturer of the bearing retainer sleeve causes the component to deform or crack, and obtaining dimensions through machining can greatly prolong the downtime. Using polymer composite materials for on-site repair, there is no thermal impact, and the repair thickness is not limited. The wear-resistance of the product and the concessions that metal materials do not have ensure a 100% contact fit at the repair site, reduce the impact and vibration of the equipment, and avoid the possibility of wear. Method of on-site repair to avoid 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 and moisture;

2. Blending repair materials;

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

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

General bearing chamber wear can be repaired within 3-6 hours. The operation is simple and easy to learn, requiring no special equipment and specialized training. Compared to laser welding, cold welding, and other technologies, it saves time and effort, and the cost is only 1/5-1/10 of the general repair cost. On-site repair also reduces equipment maintenance time and transportation costs.
