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.
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.
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.
