high friction plastic ball bearings

POM plastic bearings , PP plastic bearing POM and PA 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

high friction plastic ball bearings

(1). How does your quality compare to other bearing manufacturers in China?

YWS Bearing manufactures bearings according to ISO, AFBMA and DIN worldwide accepted standards. Our bearings are produced in our own factories, which are certified according to DIN EN ISO 9001 and ISO/TS 16949. By manufacturing to these standards,YWS can guarantee a consistent high quality product.Unlike YWS, many bearing suppliers do not manufacture their own products. They purchase Chinese bearings through middlemen, distributors, or importers. Quite often, these suppliers will change their source of supply without informing their customers, resulting in quality issues.

(2). Who does YWS currently sell bearings to?
YWS Bearing sells to many Fortune 1500 customers around the world. Our growing clientele consists of renowned automotive and industrial OEM customers.

(3). Is the delivery from China reliable and guaranteed?
YWS Bearing has a partnership with two logistic companies which undertake the export of our taper roller bearings 
from China. And we have great stock, we can send the bearings in three days if we have in stock.
