Bearings in addition to excellent quality, but also belong to a very precise parts, both high performance bearing, if used improperly in the course of, not only fail to achieve the functional effects, and very easy to make the bearing damage, lubrication, I am sure you have attention.
A bearing in the axial direction of the inner and outer rings with the stepped surface is not vertical, shaft bending, bearing bore heart, leading to the bearing inner and outer ring mounting skew, so that the bearing raceway to withstand heavy loads resulting metal peeling.
Two, resistance to impact and alternating load bearing, easily makes the raceway and move the body surface fatigue spalling. Move body repeated changes of surface contact stress, can also cause metal fatigue, thrown immobile body surface pitting and minor spalling. This spalling starting very small, then float to the surface the dents and gradually expand, was large area exfoliate.
Bearing inner ring and the shaft or the outer ring and housing bore between the mating surfaces fall into the scrap iron or hard debris, causing bearings installed raceway deformation, so that the the bearing raceway local overweight loads, produce metal peeling.
Handle directly bearing to fully wash away the sweat in hand, and coated with high quality mineral oil and then manipulate, to pay attention to the anti-rust, especially during the rainy season and summer.
In a particular operating under the premise, the bearings can get a longer life of traditional computing, in particular in the case of a light load. These special operating premise is that when the to move surface (track and move the pieces) is a lubricant film effectively separated and limit the pollutants may cause surface damage. In fact, in the ideal premise, the so-called permanent bearing life is possible.
