How to Install Oilless Bearings?

Oil-free bearing is a novel lubricating bearing that combines the characteristics of metal bearing and oil-free lubricating bearing.

First, the concept of oil-free bearings

Oil-free bearings have the characteristics of high bearing capacity, impact resistance, high-temperature resistance, strong self-lubricating ability, etc. In particular, oil-free bearings are suitable for heavy load, low speed, reciprocating or swinging and other occasions that are difficult to lubricate and form an oil film, and are not afraid of water flushing and other Acid etching and scouring. Inlaid bearings not only save oil and energy, but also have a longer service life than ordinary bearings.

2. Precautions for oil-free bearing installation

1. Whether there is dust or self-lubricating bearing mold sand attached to the surface of the bearing shell.

2. In order to avoid bumps during installation, a small amount of lubricating oil should be applied to the surface of the shaft and shaft housing.

3. Although it is a slight bump, protrusion, etc., if there is a sliding bearing, it should be removed with oil grindstone or fine sandpaper.

4. The retainer and sealing plate of the oil-free bearing must not be forced.

5. It should be determined whether there are bumps, protrusions, etc. on the mating surface of the shaft center and shaft shell.

6. The hardness of the bearing will be reduced due to overheating, so it must not exceed 100 degrees.

3. Application scope of oil-free bearings

At present, oil-free bearings have been widely used in metallurgical continuous casting machines, steel rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines.
