Device IKO rail bearing normative approach and smooth remaining

Because IKO bearing antirust treatment and packaging, and thus less than don't open the packing before installation. In addition, bearing on the smooth coating of rust-proof oil has good performance, on the common use of bearings of railway bearing or smooth filling fat, can be directly used without washing. But 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. Clean the bearing and the 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 the processing quality can fit the drawing. Device IKO bearings, because of railway bearing fit, condition, structure, common, due to many as the axis of rotation, so the inner ring interference fit. Cylindrical hole bearing, multi-purpose press pressure into, or multi-purpose hot charging method. Taper hole, device on the taper shaft directly, or use the sleeve device. Device to shell, the normal clearance fit, the outer ring has interference, usually with the pressure into the press and or have the shrink fit after cooling device. Use dry ice as coolant, shrink fit device, the moisture in the air condenses in bearing appearance. So, demand of appropriate anticorrosive measures. To the machine, just opened the package bearing. Ordinary grease lubrication, cleaning, not directly fill grease. Lubricating oil, ordinary not clean, but using the instrument or with high speed bearing, use clean oil wash, the removal of the rust inhibitor on railway bearings. Delete bearing, rust corrosion inhibitor, we can't put aside. Else, has been sealed, vocational training bureau of oil bearing, don't wash directly. Bearing device way, due to the bearing planning, premise, ordinary, more axis change, within the circle of nuisance supplication. IKO bearings with thorough and shaft with the ordinary transition fit, seat with bearing hole of the ordinary for clearance fit, thus the bearing device, more easily two-way thrust bearing axis should be fixed on the shaft, to avoid the related to the axis of rotation. Measures for the device of railway bearing common situation is the status of the axis of rotation, and the matching of the inner ring and shaft for win, with the bearing outer ring and bearing chamber for clearance fit.
