plastic deep groove ball bearing

POM and PP plastic bearing Materials with good mechanical strength and wear resistance , suitable for the production of more sophisticated plastic bearings,

working temperature from -60 °C ~ 100 °C, high strength and smooth surface , basically does not appear tension , its good self-lubricating properties and low coefficient of friction ,

while maintaining the traditional advantages of plastic bearings on the basis of precise and can be used in high speed operation .

Features :

(1) rigidity, high hardness , even at low temperatures , high impact strength 
(2) good excellent elasticity , creep resistance ;
(3) high thermal stability and very good dimensional stability ;
(4)good sliding properties , wear resistance ;
(5) physiologically inert , suitable for contact with food.
(6) Even in strong acid and strong oxidizing agents, poor paint adhesion
Main purpose :
Mechanical and electrical equipment , fitness equipment , food machinery , furniture and decorating materials

HDPE, PP, UPE material has proven to be relatively weak acid cross- environment (30% Cucl2 solution and 30% NaoH solution tested OK)

it is suitable for most acid / base / salt / solvent / oil / gas and seawater corrosion environment. With general plastic bearings oil-free self -lubricating, anti-magnetic insulation properties,

but lower mechanical strength , easily deformed. In comparison, the use of UPE material will have better strength ,

low friction characteristics and low temperature application characteristics (down to -150 °C).

Features:
(1) good corrosion resistance at a certain temperature and concentration ability of various corrosive media and organic media
(2) high mechanical strength , high toughness can be maintained cutting at liquid nitrogen temperature (-196 °C)
(3)good self- lubricating, wear high
(4) Strong anti- adhesion
(5) low water absorption, excellent electrical insulation
(6) good resistance to high energy radiation
Main purpose :
Mechanical and electrical equipment, fitness equipment , food machinery , furniture and decorating materials

PTFE high-temperature corrosion-resistant plastic bearings:
PTFE and PI as a new plastic material, proved to be all known engineering plastics and high temperature mechanical strength, dimensional stability and better performance ,

in which long-term use temperature of PTFE 260 °C, PI long-term use temperature is as high as 300 °C , and which has excellent corrosion resistance.

The ball is generally Zro2 or Si3N4 ceramic balls. In comparison the harsh operating environment of precision bearings , the drawback is due to the material itself is relatively expensive ,

so the higher cost
