Thermoplastic polymer plain bearings and sleeve bearings,
especially those lined with (Polytetrafluoroethylene), offer
exceptional properties for a wide range of applications. , commonly
known as ptfe, is renowned for its excellent chemical resistance,
low friction coefficient, and high temperature tolerance.
When wrapped or lined within a thermoplastic polymer matrix, these
bearings exhibit improved wear resistance, longer service life, and
the ability to handle higher loads and speeds compared to
traditional metal or plastic bearings. The thermoplastic polymer
provides a strong base for the lining, ensuring dimensional
stability and resistance to deformation under heavy loads.
The combination of thermoplastic polymer and also allows for
bearings that are lightweight, corrosion-resistant, and suitable
for use in both dry and lubricated environments. This versatility
makes them ideal for applications in the automotive, and food
processing industries, among others.
The installation and maintenance of thermoplastic polymer plain
bearings and sleeve bearings lined with are typically
straightforward, further enhancing their appeal for use in various
industrial settings. With their superior performance and
durability, these bearings are becoming increasingly popular as a
reliable and cost-effective alternative to traditional bearing
materials.

Carbon Steel self-lubricating bearings used high quality low-carbon
steel plate as base, sintered porous bronze as its interlayer and
the Compound of and Lead as its surface.
Our lined wrapped bearings have been developed for high duty, oil
lubricate applications. Such applications include, but are not
limited to:
- Automotive suspension struts
- Shock absorbers
- Hydraulic cylinders
- Gear pumps and motors
- Axial and radial piston pumps and motors
Our VIIPLUS range of lined wrapped bearings is suitable for dry running, low friction, low wear applications. These wrapped bearings have excellent sliding characteristics
forming a transfer film that can protect the mating metal surface.
We are able to offer lined wrapped bearings in metric plain,
imperial plain, metric flanged, metric washers, imperial washers,
metric strip and imperial strip. Special sizes can be produced to
customer requirements,

Characteristics
Metal-Polymer Low Friction Plain Bearings
Steel + Bronze Powder + /Fibre
Self Lubricating Bearings Low-Carbon Steel + Porous Bronze + Red
VSB-40 low friction bushings offer good wear and low friction
performance over a wide range of loads, speeds and temperatures in
dry running conditions
· Very good performance in lubricated applications
· Good performance in greased applications
· Suitable for linear, oscillating and rotating movements
Suitable for dry running, low coefficient of friction, lower wear,
good sliding characteristics, the transfer film created can protect
the mating metal surfaces, suitable for rotating and oscillating
movement, high chemical resistance, low absorption of water and
swelling. The VSV-40 improved the friction and much good wear
resistance over the common CSB-10 range under lubricated operation.
Strusture
1. /Polymer fibres mixture thickness 0.01~0.03mm. Lead-free bearing layer
provides an excellent initial transfer film, which effectively
coats the mating surfaces of the bearing assembly, forming an oxide
type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max.
thermal conductivity away from the bearing surface, also serves as
a reservoir for the mixture.
3. Steel backing, provides high load carrying capacity, excellent
heat dissipation.
4. Copper/Tin plating thickness 0.002mm, provides good corrosion
resistance.
