What should I pay attention to when installing Oil-free bearings?

- Oct 08, 2018-

At present, oil-free bearings have been widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, ships, steam turbines, hydraulic turbines, injection molding machines and equipment production Lines. Oil-free bearings with high bearing capacity, impact resistance, high temperature, self-lubricating capacity and other characteristics, special oil-free bearings for heavy, low-speed, reciprocating or oscillating and other difficult to lubricate and form oil film, but also not afraid of water and other acid leaching and erosion. Mounting bearings are not only fuel-efficient, energy-saving, but also have a longer service life than ordinary bearings.


So what do you need to be aware of when installing Oil-free bearings? let's take a look! Oil-free bearings have dust or self-lubricating bearing molded sand attached to the bearing housing surface.


In order to avoid scratches during loading, a small amount of lubricant should be applied to the surface of the shaft and shaft housing.


Oil-free bearings are minor bumps, bumps, etc., such as plain bearings to be removed with oil or fine sandpaper. Non-oil bearing cages and sealing plates are also absolutely non-force.


It is necessary to determine whether there are bumps, bumps, etc. on the mating surface of shaft and axle Shell. The hardness of oil-free bearings is reduced due to overheating, so it must not exceed 100 degrees. Be sure to pay attention to these details when installing Oil-free bearings.
