koyo import LNSERTED ball bearings installed attention to several issues

a. press-fit: LNSERTED ball bearing inner ring and the shaft so that a tight fit, the outer ring and the bearing bore is a more loose fit, the available koyo bearing press will be pressed onto the shaft, and the shaft together with the bearing loaded with the bearing hole, press-fit the bearing inner end surface pad made of a soft metal casing assembly (copper or soft steel).
        koyo bearing outer ring and bearing bore a tight fit, the inner ring and the shaft for the more loose fit, it can be pressed into the bearing bearing hole, then the assembly should be slightly smaller than the outside diameter of the casing bore diameter.
If the bearing rings and the shaft and housing bore are a tight fit when installing the indoor ring and the outer ring to simultaneously pressed into the shaft and housing bore, the assembly casing shall be constructed simultaneously pressing the end face of the bearing inner and outer rings.
b. heating with:
By heating the clutch bearing or bearing, using thermal expansion will be a tight fit into a song with the installation. Is a common and effortless installation method. This method is suitable for a large amount of interference koyo bearing installation, thermal loading before the bearings or separable bearing rings into the tank uniform heating 80-100 ℃, then remove from the oil as soon as possible onto the shaft, After cooling to prevent the inner face and shaft shoulder fit is not tight, LNSERTED ball bearing cooling can be re-axial fastening. Bearing outer ring and light metal bearing tight fit, the use of heating equipment bearing the thermal method, you can avoid with the surface by scratches.
With tank heating bearings, at a certain distance away from the bottom of the gate should network, or with a hook hanging LNSERTED ball bearings, koyo bearings can not be put on the bottom to prevent impurities entering the bearing sink or uneven heating, the tank must have a thermometer, and strictly control the oil temperature does not exceed 100 ℃, in order to prevent tempering effect, reduce the hardness of the ferrule.
1 anti-rust properties:
Rust inhibitor preferably insoluble in water. Grease should have good adhesion, used in LNSERTED ball bearing grease must have rust. And may form a film on the steel exterior.
(2) mechanical stability
Lead to the disclosure. Normal operation, the oil in the mechanical processing become soft. Flung by the bearing grease within the bearing. If the mechanical stability of oil is not enough, during operation, make the structure of soap grease mechanical disintegration, causing oil to be destroyed, and thus loss of lubrication.
