VIIPLUS is a growing manufacturer of self-lubricating bearings products tailored to meet the needs of various industry requirements with primary focus within the sliding bearings parts oil and gas industry.
- 1 d hydraulic bearing. Is on the basis of - 1 p combined with the oil cylinder and the working principle of the shock absorber and design a new type of material, under the condition of no oil is more wear-resisting, in addition to the product has the advantages of - 1 p, especially suitable for reciprocating force frequent tendency of big occasions. At present the product gradually replace - 1 p products, suitable for car, motorcycle shock absorber and a variety of hydraulic cylinder, etc.

- 1 d polymer surface resistance to chemical corrosion, so its corrosion resistance mainly depends on the steel back of plating and appearance. The steel back of tin or copper plated surface, can effectively prevent atmospheric corrosion; If you work in the corrosive medium, the steel back can be galvanized, etc.
