Detailed Product Description

Plastic bearing

1.POM/PA Plastic Bearings (precision plastic bearing)

Material POM and PA have excellent mechanical strength and wearing resistance, is suitable for manufacturing precision plastic bearing. With good self-lubrication performance and low friction coefficients. In addition and high speed application. Plastic bearing made with POM is the most extensive sort of all the plastic bearings. Generally the inner and outer rings made with POM or PA, cage made with PA and the balls made with glass, stainless or ceramic. These bearing could be used in some al lali environment but not proper to some acid environment.

2.HADPE/PP/UPE Plastic bearings (anti-acid and Anti-Alrali bearings)

HDPE, PP, UPE, are approved can be used in faintish acid and alkali environment (30% CuCl2 solution and 30% NAOH solution is tested ok ) Such bearings can  operate in liquid and contamination sensitive envirments as acid/alkali/salt/imprequaant/oil/gas/seawater. Have general performance of lubrication and maintenance free, none magnetism, anti-rust and eroded of plastic bearings. But these bearing have not strong mechanical strength, and easy to be out of shape, so couldnt used in heavy load and high speed application. Amony these 3 material, UPE More excellent strength and low friction and could be used to lower temperature (lowest to -150). Generally the rings and cage made with HDP. PP or UPE, balls made with glass stainless or ceramic.

3. PEEK/PL Plastic bearings (High temperature application plastic bearings)

As newly developing engineering plastic material, PEEK and Pl have been approved have the strongest mechanical strength and could endure the highest temperature among all the plastic material. PEEK could work at 260 and PL at 300 in long-term. Moreover they have excellent anti-corrosion performance could be used in strong acid and alkali environment. So generally they are used to manufacture bearings 5 to realize precision running in rigor environment. As the material is expensive, the costs are high. Generally the highs made with PEEK or PL. Cage with PTFE, peek or PL and ball with ZrO2 or Si3N4.

4. Plastic bearing made with PVDF or PTFE

As the typical type of fiuoro plastic, PTFE and PVDF have the most excellent anti-corrosion per for mance, among them as the typical type of fiuoro plastic, PTFE and PVDF have the most excellent anti-corrosion performance, among them PTFE is the best of all the plastic known to man, could be used in all the strong acid and alkali application, including HF and smoke formation H2SO4 HNO3 or HCL (98%) above. Etc. and could be used in high temperature application. PTTFE could be used to 180 and PVDF to 150. But PTFE has very low mechanical strength, easy to be out of shape and have large dimension change when the temperature rise or reduce. So couldnt be used in heave load and high speed occasion, compared with PTFE, PVDF. Has better competitive performance, generally the rings and cage made with PTFE or PVDF, balls made with glass, ceramic or stainless.

5 .Plastic ball bearings for units and plastic ball bearing units

The plastic ball bearing units specially have the performance of corrosion and wear resistance, reduce vibration and anti-bump, are free from the maintenance and so forth. Such is the most ideal solution of many difficult problem which have puzzled the industry field for hundreds years. Aim at working in different environment, the ball bearing for units made with POM, HDPE, PP, UPE, PTFE, or PEEK material, housing of the bearing units generally made with PBT material.
