POM plastic bearings, PP plastic bearings

Introduction of PTFE high temperature and corrosion resistant plastic bearings

: 2019-08-05
HDPE, PP, UPE material introduction HDPE, PP, UPE materials have been proven to be used in relatively weak acid-base cross environments (30% Cucl2 solution and 30% NaoH solution test OK), so they are suitable for most acids / bases / salts / solvent / oil / gas and Seawater corrodes the environment. It has the properties of oil-free self-lubrication and anti-magnetic electrical insulation of general plastic bearings, but its mechanical strength is low and it is easy to deform. Therefore, this type of acid-proof and alkali-proof plastic bearings is not suitable for large loads and high speeds. Disadvantages of alkaline plastic bearings. In comparison, the use of UPE material has better strength, low friction characteristics and low temperature application characteristics (minimum to -150 ℃). Generally, the inner and outer ring materials are HDPE, PP or UPE, and the cage materials are HDPE, PP or UPE, ball is glass ball, stainless steel ball or ceramic ball. In this way, the comprehensive performance of acid and alkali bearing will be greatly improved.
characteristic:
1. Good corrosion resistance, can resist various corrosive media and organic media within a certain temperature and concentration range
2. High mechanical strength, can maintain high toughness under liquid nitrogen temperature (-196 ℃)
3.Good self-lubrication and high wear resistance
4.Strong anti-adhesion ability
5. Extremely low water absorption and excellent electrical insulation
6.Good resistance to high energy radiation
The main purpose:
Mechanical and electrical equipment, fitness equipment, food machinery, furniture and decorative building materials
