BEARINGS
VIIPLUS Bearing Technologies. Your recognised global partner for
sliding bearing applications. Working together to create solutions
for the most demanding bearing applications.
VIIPLUS RANGE OF Engineered Plastics Materials
Solid Polymer Bearing & Engineered Plastic Bearings | VIIPLUS Bushings
Plastic Bearings
can be manufactured in many different types of plastic material to
suit various applications, has a good combination of properties,
including low moisture absorption, good dimensional stability, and
low friction
Engineered plastics out of thermoplastic bearing material are processed by injection moulding. This production method enables us to produce unlimited dimensions in accordance to our standard, and also parts with special designs and features.
Plastic self-lubricating bearings
EP series of high-performance engineering plastic polymer bearings
as the base material, through modification of polymer materials
technology into high-strength fibers and specialty solid
improvement in its internal grease integrated wear resistance; high
strength fiber reinforced network structure strength of the
material, the composite solid special grease allows EP series
plastic bearings with excellent self-lubricating properties and
wear resistance. Whether it is a high durability requirements the
automotive industry.
Plastic Compound Bearings
Features
VSB-70 EP series material is a thermal mould character plastic
processed by crystal engineering plastic as basic material with
proper intensifier and lubricant. The rigidity and high temperature
engineer capability is greatly improved because of the use of
intensifier, at the same time, the coefficient of thermal
expansion, moulding shrinking rate and wriggle capability
decreases, consequently, the size stability is improved, and EP
series material range is enlarged and keeps the intrinsic anti-wear
capability and anti-drug capability.
