Bearing removal and installation should be the same carefully. Careful not to damage the bearings and the parts, especially the interference fit bearing removal, the operation difficult. Therefore, prior to consideration at the design stage to facilitate the dismantling, demolition tools required design is also very important. The demolition is in accordance with the drawings of demolition methods, in order to investigate the bearing with the conditions to obtain the demolition operation foolproof.
1, the outer ring of the demolition
Remove the interference fit of outer ring, pre-set in the case of several outer circumference of the screw extrusion screws, hand tighten the screws evenly, while demolition. These usually cover screw hole blanking plugs, tapered roller bearings, etc. separable bearings, set in the shell stand shoulder several incisions, the use of pads, with the press demolition, or gently tap the demolition.

2, the demolition of cylindrical bore bearings
the demolition of the inner ring can be pulled out with the latest simple mechanical pressure. At this point, we should pay attention to the inner strength to withstand the pull.
Large-scale demolition is using hydraulic bearing inner ring method. By setting the axis of the hole to oil is easy to pull. Width of the large bearing is oil law and the drawing and used fixtures, the demolition work.
NU-, NJ-type cylindrical roller bearing inner ring disassembly can take advantage of induction heating. Local heating is in a short time, so after drawing the inner expansion method.

3, the demolition of tapered bore bearings
Remove more small adapter sleeve bearings, the shaft of the fastening support of block inner ring, the nut back a few times, beat with a hammer using the pad removal.
Large bearings, the use of hydraulic demolition is easier, the hole in the cone axis in pressurized oil, to make the inner expansion, demolition bearing method. Operation, there is the possibility of bearing a sudden prolapsed, it is best to use the nut as well as a file block.
