Plastic bearing characteristics:



PE: polyethylene (PE) is a thermoplastic resin made by the polymerization of ethylene. The material is insoluble in general solvents at room temperature, has low water absorption, no oil self-lubrication, anti-magnetic and electrical insulation, odorless, non-toxic, feels like wax, and has excellent low temperature resistance (minimum use temperature can reach -70 ~ -100 ℃ ),
Advantages: excellent chemical stability, resistance to various chemical substances such as hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, amines, sodium hydroxide, potassium hydroxide, etc. at room temperature.
Disadvantages: Nitric acid and sulfuric acid have a strong destructive effect on polyethylene, and are prone to photooxidation, thermal oxidation, and ozone decomposition. They are easily degraded under the action of ultraviolet rays. Carbon black has excellent light shielding effect on polyethylene. After irradiation, cross-linking, chain breakage, and formation of unsaturated groups can be reflected.
PE plastic bearings are generally used in a weak acid and alkali corrosion environment. The material has good lubricity and the bearing rotates smoothly. The inner and outer rings of the bearing are HDPE / PP / UPE / PE. The cage is HDPE / PP / UPE / PE. Stainless steel beads / ceramic beads.
PE plastic bearings are generally used in weak corrosion and acid and alkali working environments. Its self-lubricating performance is unmatched by other plastic bearings. The inner and outer rings of the bearing are PE, the cage material is PE or PA66, the balls are glass balls, stainless steel. Ball or ceramic ball
