PEEK and PI, new engineering plastic materials, was proven to be with the best mechanical strength, dimensional stability and high temp. endurance among all the known engineering plastics. PEEK’s long terms working temperature is 260C,Pl's long term using temperature is as high as 300C. it is with excellent corrosion resistant, can be only dissolved or damaged. by concentrated sulfuric acid, it still- works under medium. acid and alkali corrosive environment.

Thus it is used for high precision bearing manufacturing, working under harsh environment, the only advantage is high using cost due to raw material. Generally, Inner and outer ring are made of PEEK or PI, Cage is made of PTFE, PEEK,PI; ZrO2 or Si3N4 ceramic balls as rolling elements.

About Xinzhou Bearing

Xinzhou Bearing Industrial Inc. is one of the custom bearing designer and manufacturer and world wide Distributors of all types of Bearings,specializing in Ball, Needle, and Roller types (Inch and Metric Sizes) made from Ceramic (Si3N4/ZrO2), Stainless (440c/316) or Chrome Steel(SAE52100 steel); Tolerance ABEC1, 3, 5, 7.level.

In pursuit of a no-lube ball bearing,we. have developed a self lubricating PTFE based retainer. Combining these two developments, with a ceramic ball has resulted in. the ultimate low torque ball bearing capable of withstanding high or low temperatures.

Their new approach to a simple device has resulted in a life extension by an order of magnitude.

They are uniquely positioned to provide OEM' s and Distributors a full rang of engineered solutions in addition to stocking thousands of bearing and bearing related products to cost-efficiently and consistently provide just-in-time delivery.
