Composite Self-Lubricating Bushings - Lubrication Free Bushing

PTFE composite flanged bushing maintenance-free steel backing

PTFE composite bushings are the maintenance-free solution for heavy load/medium speed applications.

• The PTFE-based sliding surface allows smooth, low-friction operation without lubrication.

• The presence or continuous supply of oil or other non-corrosive fluids can be beneficial and improve the performance of these bearings.

PTFE composite bushings material

• Steel + Bronze powder + PTFE

Straight & flanged PTFE composite bushings

• maintenance-free operation
• very good frictional properties
• high load carrying capacity
• high operating temperatures
• high sliding velocity
• small operating clearance

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.

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.

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.

Bearing Properties

Advantages

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.
