Oilless Bearing Production Process and Installation Instructions

   Production Process: 

   Due to the requirements of the production process, some of the key equipment of industrial and 

mining enterprises in extremely harsh conditions to run. Due to heavy equipment, high ambient 

temperature, dust or air containing acid corrsion gas CO, SO2, etc. The equipment lubrication to 

bring a lot of problems, friction and wear serious, so far, most of the domestic enterprises 

still use the traditional oil, graese lubrication, and in fact these conditions are beyond the 

oil, grease lubrication range, prone to bearing and other friction vice bites or bitter, causing 

serious parts wear and damage, often lead to equipment outage. In order to produce continuous 

operation, in addition to the original design requirements for the inatallation of multiple 

equipment gear repair, but also to invest a large number of maintenance personnel. Severely 

reatricting the increase in productivity, spare parts and energy consumption is great, has become 

an important obstacle to the development of production. Automobile manufacturing, cement 

production, petrochemical and other enterprises have proposed to provide complex conditions of 

special lubricating material requirements. To this end, the research on mosaic self-lubricating 

composites highlights its own characteristic in material formulation and preparation process. The 

material properties have reached the international advanced level, which has solved the problem 

of lubrication under special working conditions and brought obvious Economic and social benefits.

 But because of a variety of reasons more domestic enterprises have not yet adopted, the above 

situation still exits.

    Inlaid self-lubricating composite material is a new type of anti-extreme pressure solid 

lubricating material, by the metal substrate and embedded in the substrate hole or groove in the 

solid lubricant paste composition. In the process of friction metal substrates bear the vast 

majority of the load. The solid lubricant film, which is lubricated and firmly adhered and 

uniformly covered on the friction surface, is greatly reduced in friction and wear by the solid 

lubricant in the friction, hole or groove to the friction surface. With the friction, the embedded

solid lubricant is continuously provided on the friction surface, ensuring good lubrication 

during long periods of operation.

     Installation Instructions:

     1.Should determine the axis, axle housing with the surface of the collision, protrusions and so on.

     2.Is there any dust or mold sand attached to the bearing housing surface.

     3.Although the slight bruises, protrusions, etc., if used to remove the oil mill or fine 


     4.In order to avoid the formation of bruises in the capacity, shaft and shaft shell surface 

should be wiped a small amount of oil. To inatall the bearing in the shaft when the inner ring in 

the force. To install the bearing in the shaft when the inner ring in the force, to install the 

bearing in the bearing shell, the force in the outer ring. To force the bearing force, be sure to 

pay attention to the power of the vertical and uniform, the side will hit the bearing injury. To 

avoid this.

     5.Oilless bearing retainer and sealing plate is absolutely no force. The use of hammer and 

casing installation method is generally used method, because it will damage the bearings, so do 

not directly beat. Be sure to figure in the general, so that the sleeve in the middle and beat 

into it. The hammer should be tapped lightly. In the mechanical structure, the inner and outer 

rings are tight fit, should use the the pad, be sure to force the same time added to the inside 

and outside the ring into it. If only in the inner ring after the pressure into the force, the 

force will be forced into the outer ring ball, therefore, will cause scratches in the track 

surface. To the bearing with a large margin on the shaft, in the clean oil, the bearing heated to 

80 to 90 degrees, so that the expansion of the diameter to install the method, is widely used.

    6.The hardness of the bearing, due to overheating and have to worry about, therefore, 

absolutely can not exceed 100 degrees. At this point, the bearings must use the wire to hang, or 

placed in the wire rope, supporting the board above, do not place in the bottom of the tank. When 

the bearing reaches the desired temperature (below 100 degrees), it should be removed from the 

tank immediately and quickly into the shaft. The bearing will shrink with the temperature drop, 

and some times the gap between the shoulder and the bearing face. Use the tool to press the 

bearing in the axial direction.
