What matters should be paid attention to when installing 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. 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. So, what should be paid attention to when installing oil-free bearings? Let's take a look!

Whether the oil-free bearing has dust or self-lubricating bearing mold sand attached to the surface of the bearing shell. 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.

Although oil-free bearings are minor bumps, protrusions, etc., if there are sliding bearings, oil grindstones or fine sandpaper should be used to remove them.

The retainer of the oil-free bearing and the sealing plate must not be subjected to force. It should be determined whether there are bumps, protrusions, etc. on the mating surfaces of the shaft center and shaft shell.

The hardness of oil-free bearings may be reduced due to overheating, so it must not exceed 100 degrees. Be sure to pay attention to these details when installing oil-free bearings.
