Industry requirements and installation environment for bearing products
The installation of oil-free bearings is necessary under dry and clean environmental conditions.Before installation, the machining quality of the joint appearance of the shaft and housing, the end face of the shoulder, the groove and the joint appearance shall be carefully checked.It is necessary to carefully clean and remove burrs from all joint surfaces and to remove molding sand from the raw surface of castings.
Oil-free bearings should be cleaned with gasoline or hot oil before installation, and used after boring, and ensure excellent smooth, oil-free bearings generally choose grease smooth, also can choose oil smooth.When choosing grease smooth, should choose no impurity, anti-oxidation, anti-rust, extreme pressure and other properties of superior smooth grease.The filling amount of smooth grease is 30%-60% of the volume of oil-free bearing and oil-free bearing box, so it should not be too much.The oil-free bearing of double-row tapered roller with sealing structure and the oil-free bearing of water pump shaft have been filled with smooth grease, which can be directly used by users, and can not be cleaned again.
