The Concept of Oilless Bearings and Safety Applications

    Oilless Bearings (SF-1) is a new type of metal bearing characteristics and non-oil lubricated

 bearing characteristics of the new lubrication bearings, by the metal matrix to withstand the 

load, special formula of solid lubricating material lubrication.


    Concept:

    It has the characteristic of high carrying capacity, impact resistance, high temperature 

resistance and high self-lubricating ability. It is especially suitable for occasions such as 

heavy load, low speed, reciprocating or swinging and  difficult to lubricate and form oil film, 

and is not afraid of water erosion and other acid and scouring. The majority of users generally 

reflect the inlaid bearings not only fuel-efficient, energy saving, and its working life than 

ordinary sliding bearings long. The current products have been widely used in metallurgical 

caster, rolling equipment, mining machinery, ships, steam turbines, tuebines, injection molding 

machines and equipment production lines.

   

    Application:

    SF-2 reinforced lubricating bearings: acidic polymethylated aldehydes, with high wear 

resistance ,the bearing surface with a regular arrangement of the oil storage tank assembly must

be coated with grease, eapecially for high load low speed rotational motion, rocking motion and 

often under load, opening and closing and not easy to form fluid lubrication parts, in the 

boundary lubrication conditions, long-term use without refueling maintenance, and the process of 

filling the bearing life can be more extened. Currently applicable to metallurgical machinery, 

mining machinery, water machinery, auto parts, construction machinery, agricultural machinery.

    Oilless self-lubricating bearings: The product is made of steel plate, the middle layer 

sintered spherical bronze powder, surface rolled polytetrafluoroethylene [PTFE] and lead mixture 

made. It has a small coefficient of frictiom, wear and corrosion resistance. Oilless self-

lubricating and long service life characteristics, use it can reduce costs, reduce noise, prevent 

sticky, slippery. It is widely used in a variety of mechanical sliding parts such as printing 

presses, textile machines, hydraulic trucks, tobacco machines, pharmaceutical machinery, fitness, 

micro-motor, cars, motorcycles and so on.

    Metal-based inlaid solid self-lubricating bearings: is a combination of metal bearing 

characteristic and self-lubricating bearing characteristics of the new lubricating bearings, from 

the metal matrix to withland the load, the special formula of solid lubricating material from the

lubrication. It has a high carrying capacity, impact resistance, high temperature, self-

lubricating ability and so on. The traditional oil bearing: As a result of noisy low, self-

lubricating advantages, oil bearing has become the new favorite of computer CPU fan bearings, the 

market demand is large. In addition , as people are increasingly demanding the noise. Daily 

household appliances on the application is also expanding.

     The basic requirements of the bearing material to the material depends to a large extent on

the bearing performance. Choose to manufacture rolling bearing material is appropriate, its 

performance and life will have a great impact. Under normal circumstances, the main form of 

rolling bearings in the form of alternating stress under the fatigue of the peeling off, and due 

to friction and wear loss of bearing accuracy. In addition, there are cracks, indentation, 

corrosion and other reasons caused by the abnormal bearing damage. Therefore, the rolling bearing 

should have a high resistance to plastic deformation, less friction and wear, good rotation 

accuracy, good dimensional accuracy and stability, and long contact fatigue life. And many of 

these properties are jointly determined by the material and heat tratment process.
