Crane Bearing

Bearings are an important part of machinery. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Generally, the bearing used for Overhead Crane or Gantry Crane can be the wheel group bearings, hook group bearings, pulley block bearings, reel group bearings, guide wheel sets bearing, anti-roller sets bearing, horizontal wheel sets bearing, and deflector sets bearing.

Features of Bearing Steel:

1. High contact fatigue strength

Under the action of cyclic load, the bearing is easily exposed to fatigue damage, that is, cracking and spalling, which is an important damage situation of the bearing. Therefore, in order to improve the service life of the bearing, the bearing steel must have a high contact fatigue strength.

2. Good wear Resistance

During working, not only the rolling friction between the ferrule, the rolling element and the maintenance frame occurs, but also the sliding friction occurs, so that the bearing parts are always worn. In order to increase the wear of the bearing parts, maintain the bearing accuracy and stability, and extend the service life, the bearing steel should have good wear resistance.

3. High Hardness

Hardness is one of the important qualities of bearing quality and has an indirect effect on contact fatigue strength, wear resistance and elastic limit. The hardness of the bearing steel in the application condition has to reach HRC61-65 to make the bearing achieve high contact fatigue strength and wear resistance.

4. Good Anti-Rust Performance

In order to avoid corrosion and rust of bearing parts during processing, storage and operation, it is required that bearing steels have good rust prevention performance.

5. Good Processing Performance

In the working, bearing parts have to go through many cold and hot processing steps. In order to satisfy the request of small weight, high efficiency and high quality, bearing steel should have good processing performance. For example, cold, thermoforming properties, machinability, hardenability, and the like.

In addition to the above requirements, the bearing steel shall also reach the requirements of appropriate chemical composition, average external organization, less non-metallic inclusions, external appearance defects, and the appearance of the decarburization layer not exceeding the regular concentration.

Features of Weihua Crane Bearing:

1. Application: Support the rotating parts of machinery.

2. There are 2 types: rolling bearing and sliding bearing. Rolling bearing has various standards and series, but its radial dimension, vibration and noise is bigger and its price is higher than the sliding bearing.

3. Rolling bearing is mainly constituted by outer ring, inner ring, rolling elements, bearing cage, seal and lubricant. Basing on the shape of rolling elements, rolling bearing is divided into two kinds: ball bearing and roller bearing.

4. Bearing function is to bear the radial load, or we can say it's to fix the shaft.
