Porous polymer plain bushings, such as DIN European Standard PTFE
sleeve bearings, are a type of bearing that offers excellent
performance in a wide range of applications. The porous polymer
material allows for effective lubrication and heat dissipation,
ensuring smooth operation and reduced wear. The PTFE sleeve
provides added durability and corrosion resistance, making it
suitable for use in harsh environments. Additionally, these
bushings conform to DIN European standards, ensuring compatibility
and interchangeability with various machinery components. Overall,
porous polymer plain bushings with PTFE sleeves are a reliable and
efficient choice for many industrial applications.

Line of business
Various oilless bearings, bearings for water gates, bearings
bushings and bearing plates for structures such as bridges, other
special oilless machinery such as mechanical, chemical or
electronic equipment.
Our VIIPLUS range of PTFE 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 PTFE 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,

Taking high-strength copper alloy as the base material, holes are
distributed on the working face in proportion according to the
working conditions and filled with solid lubrication column.
High-strength copper alloy provides high bearing capacity while
solid lubrication column can form lower friction pair.
Self-lubricatingbushings will support rotary, linear and
oscillating motion.VSB–10 material is designed to operate without
supplemental lubrication and will perform excellent when
lubrication is present. Low friction, low wear rate, good sliding
characteristics and very low absorption are a few of the features
of this material.
1. Low-carbon steel backing. Setting the foundation of the
bushings, the steel back provides exceptional stability, load
carrying and heat dissipation characteristics.
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. PTFE/Fibre mixture thickness 0.01~0.03mm. It is thecontact
surface for the rotating shaft. Minute partidesof thePTFE layer and
the sintered bronze material combine tocreate a solid lubricant
film, which coats the shaft.

Metal plastic composite bearing
Suitable for low speed and heavy load, intermittent operation and
swaying conditions can not oil or not allowed to oil occasions;
Simplify oil supply design, reduce maintenance and repair costs and
time;
Good wear resistance, low friction coefficient, extend the service
life of the product;
Metal plastic polymer self-lubricating rolling bearing is the
flagship product of VIIPLUS. It has excellent mechanical bearing
capacity, especially suitable for working conditions without
refueling or refueling. The usage amount of a car can reach more
than 30.Standards are similar to those of , Bronze Bushing &
DAIDO metal polymer self-lubricated rolling bearings for corrosion
resistance
