Product Description

Powder Metallurgy Plain Bearing & Valve Bushings


VIIPLUS Metallurgy bearing is a bearing and made from metallurgy material. It is a mechanical component to permit constrained relative motion between two or more parts, especially linear or rotation movement.


The application of bearing with inserted graphite to large metallurgical crane.

VIIPLUS Bronze bearing materials have been affecting the metallurgical quality of early bearing failure of the main factors.


VIIPLUS bearings are widely used in valve,metallurgy, mining, petroleum, paper making, construction and other large machinery and equipment.


The development of self-lubricating composite bearing and trend of inlay material are introduced.

The VIIPLUS Company specializes in engine bearings, friction materials, sintered components and coatings.

All the valve's internal self-lubricating bearings are sliding bearings, the whole material the use of carbon steel PTFE liner.'

Because of its superior performance, the friction in friction application fields become best material, such as sleeve bearing, sliding bearing, the valve seat, seals, pump wear ring, etc.


According to the classify of the material, the using fields also can be divided to several parts:

1. Copper-based, used in ventilator, office machinery, starter, dynamoelectric tool and aero-transport;
2. Iron-based, used in the low-velocity and high-pressure environment;
3. Iron-copper-based, used in high-velocity and high pressure environment;
4. Iron-copper-pb-based, used in middle(high)-pressure and middle(high)-velocity environment, similar to the copper-based.
As the leader of self-lubricating bushing manufacturers in China, we recognize high quality, competitive price and best service as the crucial factors for a successful corporation. Here advanced technology, equipments and management system are widely adopted to ensure the soonest delivery and first-class quality.



Lubricant fitting is provided to permit stem bushing lubrication for ease of operation.

Valve Upper and lower bushings are standard for smooth valve operation.

The most common applications in valves are, for stem material in butterfly valves, and backseat bushings and wedges in cast steel valves.

  • DN 50 - 80 

  • DN 100 1000 

  • DN 125 - 150 

  • DN 200

The valve mainly by the valve main body, the transmission system, the hydraulic pressure stands, the electrically controlled box and so on four parts is composed.


The enough lubricant grease for gear operator shall be used before ex-works manufacturer's shop. The model number and brand of lubricant grease used shall be advised to customer.

Self-lubricating - when in motion oil rises to the surface for lubrication and restores itself when at rest.

After forming, sintering and sizing, the bearings are vacuum impregnated with SAE 30 oil that provides lubricant which is metered from the bearing to the shaft during rotation.

Standard off-the-shelf oil impregnated bronze bearings should function satisfactorily in temperatures ranging from 10F to 220F.

RoHS, REACH, DFARS compliant


Advantages Of Powder Metallurgy Process


· Do not need or only very little machining

· High usage rate of material(more than 95%)

· Parts size consistency is good and stable. The precision can reach 0.01mm.

· The material composition can be adjusted according to the customers’requirement of the parts performance.

· Do the treatment on the surface of the parts according to customers’ requirement to improve the strength and hardness.

· Due to the die forming, we can customize the complex shape or special profiled parts which other machining can not do.

· Because suitable for mass production, the production efficiency is high and the cost is lower than machining.
