Double row tapered roller bearing disassembly Maintenance Tips

Many people use the bearing installation method to install properly, resulting in double-row tapered roller bearing damage. Therefore, how to properly install bearings, hope more comprehensive understanding of the bearing mounting and dismounting:
Clear the bearing ring, a thin layer of paint recommended creep corrosion resistance, the friction between the mating surfaces to prevent corrosion. Loosen the bearing bolt?. Together with the bearing out. Please note that the demolition of former double row tapered roller bearing end of the shaft. Should be on the other side of the bearing shaft bolt loose, so try not to each other at both ends of the bearing strength and failure. First with a hex wrench to loosen the locking screw eccentric, eccentric to the roof on the sink hole, loosen the rotary shaft eccentric small iron bar.
  Double row tapered roller bearing proper installation, use is very important. Hope that we can use in the future, use the correct installation method. Installation, according to their type and size, select mechanical, hydraulic, or other heating methods. Install bearing force is applied, rather than by rolling from a circle, double row tapered roller bearing rings, or is likely to cause damage raceways. But in any case, you can not directly tap the bearing ring, cage, rolling or sealed.
1 Install eccentric. First, double row tapered roller bearings on the steps and hand-tighten along the axis of rotation eccentric condoms. Then insert a small iron bar or on the sink hole withstand eccentric. Along the axis of rotation of the small iron hand hammer percussion. Eccentric securely installed, and finally the eccentric locking hex screws.
2 fixed double row tapered roller bearings, do not tighten the bolts, bearing coats rotating bearing. Then tighten the bolts good relationship, but also the installation of a bearing, the other end of shaft rotation several times, so that the bearing itself automatically find the location.
3 bearing and the bearing lubricant topcoat, and then assembled with bearings and bearing sleeve on the shaft. Pushed to install the required location.
4 double row tapered roller bearings installed, you must first cancel the fixed bearing jacket, and in magazines journal surface is smooth, polished clean, and rust oiled and lubricated (the shaft bearing, allowing a slight rotation).
