Product Description

Metal-Polymer Low Friction Plain Bearings

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.




Metal-Polymer Low Friction Plain Bearings




Product introduction

- 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.

Product specialty

Chemical properties

- 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.

The main factors influencing the life span
1) the influence of PV valuePV value is to determine the wear life of - 1 effective index. If required longevity, PV value must be reduced.
2) the influence of ambient temperatureThe higher the temperature, - 1 the shorter service life.
3) dual effects Dual USES alloy steel or hard chromium plated shaft, surface roughness Ra - 0.4-0.63 range, - 1 bearing service life can be improved significantly.In addition to standard products show in the catalogue, you can also provide non-standard products according to customer's requirement or order.
