Whether ball bearings installation is correct or not affects the accuracy, lifetime and performance of ball bearings. Therefore, the design and assembly departments for the installation of bearings should be adequately studied. Installation should be in accordance with standards of practice. The projects’usual operating standards are as follows:
(1) Cleaning bearings and connecting bearing components
(2) Check the connected components of size and finishing
(3) Installation
(4) The inspection of the installed bearings
(5) The supply of lubricant: open the ball bearings package in the forthcoming pre-installation. General grease lubrication, non-cleaning, is directly filled with grease. Oil lubrication generally do not have to wash. But the instrument used or high-speed bearings and so on should use clean oil washed to remove anti-rust coated bearing on the agent. To remove the rust inhibitor of the bearings, easy to rust, it can not be placed disregard. Furthermore, the bearing grease has been sealed, not washing directly. Bearing installation method, because the conditions vary with the bearing structure, generally, as more axis rotation, so the inner need for interference fit. Cylindrical bore bearings, pressed into multi-purpose press, or multi-way with hot equipment. Cone hole occasions, directly installed in the taper shaft, or sleeve installation. Install-to-case, general clearance with more than the amount of the outer ring had a surplus, usually pressed into the press, or have cooled with the method of installation of shrink. Using dry ice as the cooling agent, shrinkage with the installation of the occasion, the air will condense the moisture in the bearing surface. Therefore, we need appropriate measures of preventing from rust.
Periodic inspection or replacement of components, bearings need to be demolished. Usually shaft and bearing housing should continue to be used practically, the bearings are often forced to be used continuely. Therefore, take into account of the structural design when the demolition bearings, not to damage ball bearing shaft bearing boxes and other components, while also preparing the appropriate removal tools. Static with the demolition of the ring, the tension can only be added to the ring, the ferrule may not pull through the rolling body.
