INA imported bearing installation disassembly and matters needing attention

Before the installation note 1) Preparation of bearing because of INA bearings imports through antirust processing and packaging, so do not open the packing before installation. In addition, the coating on bearing anti-rust oil has good lubrication performance, for the general purpose of bearing or bearing grease filling, can not directly use cleaning. But for the instrument bearing or bearing for high-speed rotation, the application of clean cleaning oil washed away anti-rust oil, when the bearing is easy to rust, not for a long time. 2) Shaft and the shell inspection, cleaning, INA import bearings and shell, confirm no scar or mechanical processing of burr. Shell has absolutely can not have abrasives ( SiC and Al2O3, etc. ) Sand, scraps, etc. Next inspection shaft and shell size, shape and machining quality are consistent with those drawings. Before install bearing, in the inspection of shaft and the shell of the mating surface coating machine oil. Bearing the installation method of bearing installation method for bearing type and matching conditions are different. Due to the more commonly as the axis of rotation, so the inner ring and outer ring can respectively USES the interference fit and clearance fit, the outer ring rotates, the outer ring USES the interference fit. ( 1) Installed pumped into general use press, also can use a bolt and nut, when forced to use hammer into the pack. ( 2) Heat installation will INA imported bearing in oil heating makes its expansion installed on the shaft after heat method can avoid unnecessary force, the bearing in a short time to complete installation work. Heating considerations: (1) General heating does not exceed 100 ℃. 2) Do not allow the bearing contact with the bottom of the tank. Additional heat induction heating device can be used to heat the bearing installation so that it has expanded again after installed on the shaft. Removal periodic inspection or replacement of the bearing parts, the need to remove the INA bearing imports. Usually shaft and bearing box almost all want to continue to use, bearing also tend to continue to use. Structure design, therefore, want to consider removing bearings, not damage the bearings, shaft, bearing housing and other parts, but also to prepare the proper removal tool. Remove the interference fit ring, can only add tension on the ring, not by drawing roller ring.
