PEEK (Polyketone) and (Polytetrafluoroethylene) oilless bushes are
precision components made from a metal-polymer hydrodynamic
composite material. This unique material combination offers
exceptional performance characteristics in demanding applications
where lubrication is limited or not feasible.
The metal-polymer composite structure provides both the strength
and durability of metal and the low friction and wear resistance of
polymers. The PEEK and components are impregnated or bonded to the
metal base, creating a homogeneous and integral bush that can
withstand high loads, temperatures, and speeds.
The oilless design of these bushes eliminates the need for external
lubrication, reducing maintenance costs and downtime. The
hydrodynamic properties of the composite material allow for the
formation of a lubricant film between the bush and the mating
surface, further reducing friction and wear.
PEEK / oilless bushes are commonly used in applications such as
automotive, aerospace, and precision machinery where reliable and
long-lasting performance is crucial. They are particularly suitable
for applications where traditional oil-lubricated bushings are not
feasible due to environmental or operational constraints.
Overall, PEEK / oilless bushes made from metal-polymer hydrodynamic
composite material offer a unique solution for demanding
applications that require low friction, high wear resistance, and
reliable performance without the need for external lubrication.

What is a self-lubricating bearing?
Self-lubricating bearings are divided into composite
self-lubricating bearings, solid mosaic self-lubricating bearing
shaft, bimetallic materials
Self-lubricating bearings, special materials, self-lubricating
bearings, according to different uses and conditions, use a
different self-lubricating bearings.
One of the major categories of solid mosaic self-lubricating
bearings (referred to as JDB) is a combination of metal bearing
characteristics and characteristics of non-oil lubricated bearings,
lubricated by the metal matrix to bear the load, the special
formula of solid lubricating material.
It is characterized by high load-bearing capacity, impact
resistance, high temperature resistance and self-lubricating
ability. It is especially suitable for occasions where it is
difficult to lubricate and form oil film, such as heavy load, low
speed, reciprocating or swinging, and erosion of water and other
acid And erosion. The products have been widely used in metallurgy
continuous casting machine, rolling equipment, mining machinery,
mold, lifting machinery, textile machinery, wind power generation,
shipbuilding, steam turbine, turbine, injection molding machine and
equipment production line. Wear resistance is double the normal
sleeve.

Strusture
1.PEEK/ 0.30~0.50mm. It has high wear resistance and low friction
even only minute of lubricant are supplied. The bearing surface
carries a pattern of circular indents which will be filled with
grease on assembly of the bearing.
2.Bronze layer 0.20~0.35mm. A special composition of powdered
copper is thermally fused to the steel backing. This contact layer
acts as an anchor for the layer and conducts the thermal build up
away from the bearing surfaces.
3.Steel backing.Setting the foundation of the bushings, the steel
back provides exceptional stability, load carrying and heat
dissipation
