1, the importance of lubrication

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

Rolling mill bearing lubrication grease lubrication oil lubrication and divided into 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 used in lithicgrease, lithium base embellish the characteristics of the fat is good water resistance, high drop point, to be used in

Damp and contact with water mechanical parts. Grease according to the liquidity is divided into several levels of needle into. The greater the degree of needle into numerical, said the more soft grease.
The domestic production of the roller bearing grease, is by the senior fat acid and synergistic agent compound and into the multiple compound lithium base fat, also suitable for rolling mill bearing lubrication.

3, a grease filling quantity

The grease filling quantity, to fill the bearing and bearing a third of the half shell space and advisable, if you add too much fat, due to stir and hot, can make the fat metamorphic progression or of qin. High speed should only fill to a third or less. When speed is very low, to prevent external foreign body into the bearings inside, can fill shell space.

4, grease, replacement

The service life of the grease is limited, the lubrication performance in the process of use gradually reduce the wear is increasing, so a certain amount of time intervals must add replacement.

The added period and bearing grease the structure, speed, temperature and environment and so on, should according to the operation condition of the enterprise specific determined. Grease replacement should pay attention, different grades of grease can not be mixed with, contain a variety of fat thickener mix, will destroy the lubrication of structure and consistency, if must be replaced by different grades of grease, should be the bearings inside the original completely removed grease, then added to the new requirement.
