Rules for mounting rolling bearings

It is difficult to formulate general principles for mounting rolling bearings, as their diversity is enormous. On cleanliness and lubrication with the right grease, as well as precise selection of slack (if such activities are carried out at all) we have already said. It is also worth mentioning the need to maintain the rules of bearing embedding on pins and housings. In any case, the force required to perform this action should be applied in this way., so as not to damage the treadmill and balls or rollers under any circumstances. In other words,, you can not exert pressure through the treadmill yes, so that the forces move from the raceway through the balls (Roll) to the second treadmill. It is therefore important to choose the right bushings, through which we will force and place the outer and inner ring of the bearing at the individual stages of mounting. It is also important to properly immobilize the bearing in the socket using properly functioning retaining rings or axial elastic rings. The axial and transverse play of the entire bearing on the shaft or in the socket in practice disqualifies such a mounting and will certainly cause imminent damage to this element.
In modern automotive designs, rolling bearings are increasingly rare, the lubrication of which is left to service workshops. The bearings inside the mechanisms pose no problems, while the external ones are usually special constructions, application-specific and loaded with grease and non-replaceable seals, sufficient for the entire service life.
Standard bearings in the automotive industry are almost exclusively "covered on both sides", which eliminates the need for additional seals. More and more often, car manufacturers decide to design their own rolling bearings, ignoring standardization recommendations. In many cases, special bearings, for example, integrated into part of the mechanism (the wheel hub or shaft in the gearbox) allow for better refinement and weight reduction or strengthening of a specific element. In large-scale production, the production costs of such structures may be lower, though without a doubt, in the event of damage to the bearing associated with other parts of the mechanism, the cost of repair increases.
