The oilless bearing bush, featuring a yellow-finished tin or copper
plating, offers a highly efficient and maintenance-free bearing
solution. This unique design eliminates the need for regular
lubrication, significantly reducing operational costs and
maintenance requirements.
The bearing bush is constructed from high-quality materials,
ensuring its durability and long-term performance. The tin or
copper plating not only adds a protective layer but also enhances
the bearing's lubricity, resulting in smoother and friction-free
operation.
The yellow finish of the plating not only provides a visually
appealing appearance but also serves as a corrosion-resistant
coating, further extending the bearing's lifespan.
This oilless bearing bush is suitable for a wide range of
industrial applications, including machinery, automotive
components, and other equipment that require reliable and
lubrication-free bearing solutions. Its efficient performance and
ease of installation make it a cost-effective choice for various
industries.
In summary, the oilless bearing bush with tin or copper plating in
yellow finish offers a highly efficient and maintenance-free
bearing solution that is suitable for a wide range of industrial
applications. Its durability, long-term performance, and visually
appealing appearance make it a preferred choice for many
industries.

Composite dry sliding bearings maintenance-free and
space-saving
Composite dry sliding bearings are primarily used for bearing
arrangements where heavy loads should be supported and where
rotational or oscillating movements are relatively slow. Due to
their good sliding properties and compact design, these plain
bearings are particularly suitable for bearing systems in which:

Bushing POM Bush China Manufacturer
· marginally lubricated bushings for grease or oil lubricated
applications
· Standard parts contain grease indents in the sliding layer; plain
sliding layer available by request
· Optimum performance under relatively high loads and low speeds
· Suitable for linear, oscillating and rotating movements
· Wide range of parts available from stock
Suitable for rotating and oscillating movement, less maintenance
requirements due to the long re-lubrication intervals, lower wear,
lower susceptibility to edge loading, no absorption of water and
therefore no swelling, good damping behaviours, good resistance to
shock loads
Strusture
1. POM thickness 0.30~0.50 mm. It provides high wearresistance and
low friction even with only minute volume oflubricant are supplied,
this bearing surface carries a pattern of circular indents which
should be filled with grease on assembly of the bearing.
2. Sintered bronze powder thickness 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 PTFE layer
and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel.Setting the foundation of the bushings, the
steel back provides exceptional stability,load carrying and heat
dissipation characteristics.
