Product Description

Self Lubricating Bushing Plain Bearings



VIIPLUS is a professional supplier of self-lubricating bearings in China.Set good quality and service as one.Size customizable.


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. Its performance is similar to DP4, at present the product gradually replace - 1 p products, suitable for car, motorcycle shock absorber and a variety of hydraulic cylinder, etc.

Application field

Agricultural machinery, tractors, combine harvesters, crop sprayers, bulldozer, grader, etc;Auto industry: the power steering pump, steering thrust pads, brake disc, shock absorber, door hinge, wiper, chairs, illustrates, air valve and electromagnetic pavilion, etc.;Office business machines, photocopiers, fax machines, printers, E-mail processor, etc.;Hydraulic components and valves, gear pump, ram pump, vane pump, ball valve, butterfly valve, cylinder, cylinder and other hydraulic components, etc.;Household appliances: refrigerators, air conditioners, vacuum cleaners, sewing machine, washing machine, microwave oven and fitness equipment, etc.And other logistics machinery, packaging machinery, textile machinery, port machinery, mining machinery, forest machinery and all kinds of engineering machinery and equipment.


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.

Wear-resisting performance

1) "running-in stage: PTFE surface layer mixture to dual surface fill the dual surface depressions, and formation of transfer film, at this point, the friction coefficient is bigger, material wear faster.
2) "stable" wear stage: after running-in friction into PTFE, the friction between the low and stable friction coefficient, low wear rate of materials smoothly.
3) a "dramatic" wear stage: porous PTFE lubricant consumption of pore, the friction interface can't get enough amount of lubricant. Bad lubrication between friction surface, the friction coefficient rising rapidly, material grinding rate dramatically fast, until 70% bronze exposed, 1 life close to the end.


The main factors influencing the life span


1) the influence of PV value
PV value is to determine the wear life of- 1 effective index. If required longevity, PV value must be reduced.
2) the influence of ambient temperature
The 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.
