Import bearings in use process should strengthen the maintenance and monitoring, in order to prolong the service life.

1, keep lubricant road unobstructed, according to the rules of the lubricants chosen species, regularly enough charging lubricant. Ensure that the roller surface rolling and roller and raised edge of sliding surface, keep good lubrication oil wax.

2, regular check the sealing of seals, to replace damaged the seal. To ensure the sealing performance bearing, in order to prevent the water, oxidation iron into the bearings, prevent bearing of lubricant outside leakage.

3, combined with the enterprise actual, actively carry out on the bearing the operation condition of monitoring.

Noise monitoring: normal operation should be smoothly humming, regular monitoring and with the voice of the normal when compared to detect abnormalities.

Lubricant monitoring: normal lubricant should be clear and clean, if lubricant has become dirty, there will be wear particles or pollutants.

Temperature monitoring: the temperature rises, the running will appear unusual. The company has set up a file in temperature monitoring work, willing to more extensive services for clients.

Second, rolling mill FAG bearing lubrication

1, the importance of lubrication

INA bearing of the lubrication is use of oil film will relative movement in the surface rolling separated from each other, and not because of rough contacts lead to excessive wear and failure. If users can pay high attention to the bearing lubrication technology, it can guarantee to the working life of the set period, can still maintain a stable performance and rotation precision.

2, grease, type and performance

Mill bearing the lubrication is divided into SKF grease lubrication oil and lubrication grease lubrication, the advantage of lubrication facilities simple, grease is not easy to leak, have certain waterproof, gas and other debris into bearing ability, so usually widely used grease lubrication. In the heavy, high speed, high temperature condition oil lubrication.

Grease is by the basic oil, thickener and the reclamation and agent composition. Base oil viscosity lubricating grease on the play an important role, the composition of the thickener for fat properties, especially the temperature characteristic, water resistance, analyse is oily, etc have important influence, the reclamation and agent is mainly used for gasification, enhance the grease of rust and extreme pressure properties.

Grease according to the type of thickener to different classification, divided into lithium base, the base and so on many kinds. Rolling mill bearing commonly used in lithicgrease, lithium base embellish the characteristics of the fat is good water resistance, high drop point, to be used in wet and contact with water mechanical parts.
