What Is The Introduction Of Plastic Bearings?
First, precision plastic bearing introduction: precision plastic
bearing than traditional plastic bearing precision and tolerance
Precision plastic bearings using suitable for precision machining of
materials inside and outside the ring, rolling body and a holding frame,
on the basis of keeping some traditional advantages of plastic
bearings, can be applied to the precision and high speed operation in
some extreme conditions.
The general inner and outer ring materials adopt POM, PPS, or peek, and
the cages are made of glass fiber reinforced nylon 66 (rpa66-25), or
peek, and the rolling bodies are glass balls, stainless steel balls or
Two introduction: plastic bearing resistance, corrosion corrosion
resistant plastic bearings for those different application solutions of
various materials, even under the most severe acid / alkali / salt /
solvent / oil / gas / water erosion is still able to operate freely, to
ensure ideal durability and life expectancy.
Three, acid and alkali resistance plastic bearings introduction: anti
acid plastic bearings, HDPE, PE, UHMWPE and other materials have been
shown to be able to cross for a relatively weak acid environment (CuCl2
and 30%naoh solution to test OK 30%), strong acid and alkali environment
can use PVDF and PTFE PTFE materials, these materials can be used in
concentrated acid all and concentrated alkali occasions, even including
HF and fuming sulfuric acid nitric acid environment (more than 98%).
Fourth, high temperature resistant plastic profile bearing: high
temperature resistant plastic bearings, PVDF, PTFE (Teflon), PPS (PPS),
Peek (PEEK), PI (polyetherimide) and other materials have proved to be
some ideal material for high temperature plastic bearings, these
materials can be used in PI temperature 290 C environment for a long
time, short-term temperature resistance can reach 350 degrees high, is
currently all known engineering plastics is one of the best high
Five, plastic bearing and plastic ball bearings: plastic ball bearing
has no bearing properties of other plastics, such as light weight, easy
installation, corrosion resistance, free of maintenance, but also has
the unique characteristics of commonly used cast iron or stamping block
do not have vibration impact energy.
With the continuous development of all kinds of new plastic materials,
this kind of bearing is more and more applied in various engineering. Source: Internet, finishing.
