FAG bearing grease filling can be done in a long time after not should be added and the structure of sealing device is also simple, so widely used.

A grease lubrication in sealed type bearings in advance of the grease filling sealing way, installation bearing inside and outside lap to the appropriate over surplus quantity in shell and internal filling grease right amount, every once in a while for supplement or replacement of the filling way for fat.

In addition, the bearings inside high-rigidity bearing configuration of combination at the machinery to need lubricating bearings, but also USES the pipe connections to all lubricating the concentration of fat in for way.

1) the grease filling quantity

Rui fine mechanical and electrical sums up the production of all kinds of material bearing maintains a grease filling quantity of the enclosure with the structure of the shell and volume and different, generally filling to volume of the third-1/2 advisable.

Filling quantity too much, grease for mixing fever deterioration, aging and softening, should take note.

But for low speed bearings, to prevent foreign invasion, and, sometimes, filling to volume of the two-thirds-1. 2) the grease of complement and replacement

Can production of several bearing steel materials bearing grease of complement and replaced with lubrication methods have close relations, and whatever the way, must use clean grease, and pay attention to prevent external foreign invasion.

Bearing clearance of the industry standard of the grease should be added for the same day, brand grease.

Added a grease, particularly important is to ensure that new grease really into the bearings inside

Sliding bearing is to point to in sliding friction work under the bearings. Sliding bearing specific smooth, reliable, without noise etc. Characteristics. In liquid lubrication condition, sliding surface is oil and not direct contact with separate happened, also can greatly reduce friction loss and surface to wear, the oil film still has certain ability and vibration.

 

There are many kinds of sliding bearings, the classification method has the following kinds:

 

According to the direction of can bear load can be divided into radial (to the heart) sliding bearing and thrust (axial) sliding bearing two kinds.

 

According to the lubricant kinds can be divided into oil lubricating bearing grease lubrication, bearings, water lubrication bearing, gas bearing, solid lubrication bearing, magnetic bearings and electromagnetic bearing seven categories.

 

According to the lubrication film thickness can be divided into thin film lubrication bearing and thick film lubrication bearing two kinds.

 

According to the axle bush materials can be divided into bronze bearing, cast iron bearing, plastic bearing, precious stones bearing, powder metallurgy bearing, lubricated bearing and oil bearing.

 

According to the structure of bearing can be divided into round bearings, elliptic bearing, three oil leaves bearing, stepped surface bearing, on tilting-pad bearing and foil bearing.

 

Sliding bearing applications, according to the specific different environment using different rolling bearing, such as the following:

 

Work particularly high speed bearings, such as grinder spindle;

 

Bear great impact and vibration load bearing, such as rolling mill roll;

 

Require special precision bearings, small size of the radial demand bearing;

 

The assembly process requirements bearing division of occasions, such as the crankshaft bearings.
