SKF bearing material the metallurgical quality was rolling bearings of the failure of early influence factors. As metallurgy technology (such as bearing steel vacuum deairing with etc) progress, raw material quality improved. Raw material quality factors in non-standard bearings failure analysis of the proportion of the has obviously decreased, bearing but it is still bearing the main influence factors of failure.
First, reasonable structure design and have advanced, just can have a long bearing life. Bearing manufacturing to want to pass commonly forging, heat treatment, turning, grinding and assembly process of multi-channel processing operations. The processing technology of rationality, advanced, stability will also affect the life of the bearing. Which influence the quality of the finished product bearing heat treatment and grinding process, often with the failure of a more SKF bearing direct relationship. Non-standard bearings in recent years on a work surface layer of the metamorphic research shows that the grinding process and bearing surface quality closely.
SKF bearing structure, cooperate because, conditions and different, generally, it is because for axis rotation, so inner circle over surplus to cooperate. Cylindrical holes bearing, multi-purpose pressed into the press, or use hot charging method. Cone hole occasions, installed directly to the taper axis, or with the sleeve installation.
Installation to shell, with general clearance, outer ring had surplus quantity, usually with pressed into the press, or have after cooling method of installation with cold. With dry ice for cooling agent with the occasion of installation cold, moisture from the air will be condensed in the surface of the bearing. So, need appropriate antirust measures.
Regular inspection or replacement parts, need to remove the bearings. Usually axis and bearing box is just going to continue to use, non-standard bearings often also will continue to use. Therefore, the structure design must consider to remove SKF bearing, not damage bearing box and other parts, and at the same time we have to prepare appropriate remove tool. Remove the static with rings, will only add in the tension on the collar, not through drawing roller rings.
Bearing temperature, usually have a bearing the outdoor temperature that out, if use oil hole can direct measurement of non-standard bearing outer ring temperature, bearing is more appropriate. Usually, the temperature of the bearing with running bearings began to slowly rising, 1-2 hours to achieve stable state. SKF bearing temperature of the heat capacity normal machine, heat, speed and load and different. If the lubrication, installation of appropriate, the bearing temperature sudden will rise, can appear abnormal high temperature, then must stop operation, and take the necessary measures to prevent it.
