Steel-Backed Tin-Plated Thrust Washer Bearing with Coating is a
high-performance bearing designed to withstand heavy loads and
provide smooth, reliable operation in thrust applications.
Constructed with a steel backing, this bearing offers exceptional
strength and durability, making it suitable for use in demanding
industrial environments. The tin plating adds an extra layer of
protection, resisting corrosion and wear, while also improving
lubrication properties.
The (Polytetrafluoroethylene) coating provides a low-friction
surface that significantly reduces friction and heat generation
during operation. This not only enhances the bearing's efficiency
but also extends its service life.
The thrust washer design of this bearing allows it to distribute
loads evenly, reducing stress concentrations and minimizing wear.
Wh you're upgrading existing equipment or installing new machinery,
the Steel-Backed Tin-Plated Thrust Washer Bearing with Coating is
an excellent choice for improving performance and reliability.

Thrust Washer Bearing
THRUST WASHER BEARING SUPPLIER PLAIN BUSHES
Simply called is three layers of composite meaning, -1 refers to
the material description is , SF-1 bearing is a layer of steel
plate as the matrix, a layer of intermediate sintered spherical
bronze powder, a layer of inner surface rolling
polytetrafluoroethylene () and lead mixture, by three layers of
rolling bearing. And has the characteristics of small friction
coefficient, wear resistance, high corrosion and no oil
lubrication.
The basic concept
Simply called is three layers composite meaning, -1 refers to the
material description is , SF-1 bearing is a steel plate as the
matrix, a middle layer of sintered spherical bronze powder, a layer
of inner surface rolling polytetrafluorethylene () and lead
mixture, by three layers of rolling Ming Sheng bearing. And has the
characteristics of small friction coefficient, wear resistance,
high corrosion and no oil lubrication. Using this product can
reduce the cost, reduce the mechanical volume, avoid the phenomenon
of biting shaft and reduce the mechanical noise and so on. Sf-1
products have been widely used in the sliding parts of all kinds of
machinery, such as printing presses, textile machines, fitness
equipment, hydraulic carriers, micromotors, automobiles,
motorcycles and agricultural and forestry machinery.
Thrust washers are flat washers that are located between a rotating surface and a stationary
component. They support the axial load or side to side motion on a
shaft and prevent movement along that shaft. The thrust washer
provides a surface on to which a bearing is supported.
Sf-1 oil-free bearing is a sliding bearing made of steel plate as
base, sintered spherical bronze powder in the middle, and a mixture
of rolled polytetrafluoroethylene () and lead on the surface. It
has the characteristics of small friction coefficient, wear
resistance, good corrosion resistance, no oil lubrication. This
product can reduce the cost, reduce the mechanical volume, avoid
the phenomenon of biting shaft and reduce the mechanical noise and
so on.
1, no oil lubrication or less oil lubrication, suitable for the
place can not be refueled or difficult to refueling, can be in use
without maintenance.
2, Good wear resistance, small friction coefficient and long
service life.
3, has the right amount of elastic-plastic, can distribute the
stress on a wider contact surface, improve the bearing capacity of
the bearing.
4, the static and dynamic friction coefficient is similar to
eliminate the crawling at low speed, so as to ensure the working
accuracy of the machine.
5, can make the machine to reduce vibration, reduce noise, prevent
pollution, improve and optimize the working environment.
6, in the process of operation can form a transfer film, to protect
the use of grinding shaft, no biting shaft phenomenon.
7,The hardness requirements of grinding shaft are low, and the
shaft without quenching and tempering treatment can be used, thus
reducing the processing difficulty and cost of related parts.
8, thin-walled structure, light weight, reduce the mechanical
volume.
9, the back of steel can be electroplated a variety of metals, can
be used in corrosive media; At present, it has been widely used in
the sliding parts of various machines. Such as automation machinery
and equipment (scale, swing, slide, bending, cyclotron, turning
parts) guide bush, hydraulic motor, hydraulic cylinder gear pump
pu, textile machinery, vending machines, plastic molding machine,
die-casting machine, rubber machine, tobacco machine, fitness
equipment, office machinery, hydraulic truck, automobile,
motorcycle, forestry machinery, etc.

SF-1 Thrust Washer Advantages:
1.Can be used where no oil can be applied or oil is difficult to be
applied.
2.Low wear, low friction and with long life.
3.Low stick slip properties ensuring accuracy of machine operation
under low sliding speeds.
4.Low vibration, low noise and non-pollution in operation.
5.and Lead filler is transferred to the mating shaft to improve
running properties.
