Oil-free bearing devices must be carried out under dry, clean environmental conditions. Before the device should be carefully checked the cooperative appearance of the shaft and the shell, the end surface of the shoulder, the groove and the processing quality of the joint appearance. It is necessary to carefully clean and remove burrs for the appearance of all cooperation, and it is necessary to remove the molding sand for the unprocessed appearance of castings.
The oil-free bearing device should be cleaned with gasoline or kerosene first, and then used after being dry, and ensure excellent smoothness. The oil-free bearing is generally selected to be grease-smooth or oil-smooth. When smooth grease is used, smooth grease with excellent properties such as no impurities, anti-oxidation, anti-rust and extreme pressure should be selected. The amount of smooth grease filled is 30%-60% of the volume of oil-free bearings and oil-free bearing boxes, and should not be excessive. The double-row tapered roller oil-free bearing with sealing structure and the oil-free bearing of the pump shaft have been filled with smooth grease, and the user can directly use it, and can no longer clean it.
