Product Description

Polymer sliding bearing alloy bearing assembly dimension precision

Metal composite bearings have been relatively successful in replacing traditional lead-bearing bronze or bimetallic bearings in many lubrication applications.But until recently, ptfe funds are still unable to match the metal genera - polymer sliding bearing alloy bearing assembly dimension precision, which limits its application in specific areas, in these areas, the axial clearance control to the improvement of operation efficiency, or noise, vibration and no comfort plays an extremely important role.


VIIPLUS Bearings supply a variety of pump metal bushings including brass bushings, steel bushing, & bronze bushings. If you already know which type of metal bushing is right for your application, you can quickly navigate to it below for more information:

Self-lubricated bearings have been used in vane pumps and the results show that the metal polymer composite straight liner has excellent tribological performance under dry, edge and hydrodynamic lubrication operating conditions, providing excellent pump reliability.


In order to improve the reliability of the pump, VIIPLIUS provides a self-lubricating bearing solution.


Provides a wide variety of self-lubricating sliding bearings to meet or even exceed the needs of a variety of applications.It is used in rotating, swinging and sliding motions and in a variety of difficult operating conditions such as high static or vibrating loads, temperature limits and friction conditions.

VIIPLUS SLIDING BEARING PTFE series self-lubricating bearings can meet the unique application requirements of the fluid power industry.We can provide complete solutions, reliable performance under high load and high speed, can resist cavitation and chemical corrosion, suitable for today's advanced fluid power applications, in gear pump, piston pump, vane pump, compressor, cylinder and other industries have a wide range of application.

The benefits of self-lubricating straight bearings are as follows:
Self-lubricating bushing with ptfe-based low friction bearing cladding for extended service life to avoid lining and shaft damage while operating under dry or boundary lubrication conditions
Thin - walled, single - piece structure allows for compact, lightweight pump design
Easy to assemble in pump without expensive tools and equipment
Environmentally friendly lead-free bearing assembly.

Bush for plunger pump and motor bearing

This requires self-lubricated bearings to provide high wear resistance, fatigue and flow erosion hydrodynamic composite bearing bearing bush solutions
The technical requirements and specific functions of sliding bearings in this application are the most demanding requirements of any high-power hydraulic components.In addition to withstand the temperature range in - 50 ℃ to + 140 ℃ as well as the wide range of lubricant viscosity change, must be able to withstand extreme high load bearing oscillation velocity and boundary lubrication conditions.

VIIPLUS Lubricating and sealing characteristics of the guide bearing were researched by the aid of hydrodynamics and tribologys.

Advantages of high performance bearings

Maintenance-free bearings are used in common hydraulic fluid and many types of water emulsion conditions, suitable for vane pumps, gears, plunger pumps and motors.In addition to their excellent frictional and anti-wear properties, they are stable and reliable under required loads and speeds, making them suitable for many hydrodynamic applications.


Application requirements

Variable displacement axial piston pumps are used in many industries of high power hydraulic systems, including aerospace, automotive, construction equipment, agricultural equipment, machine tools, etc.These pumps provide variable flow from zero to maximum capacity for the system actuators.The change of flow is realized by the change of the position of the swash plate.

We provide bearing solutions for hydraulic pumps and motors, including shaft bearings, half bearings, thrust blocks, wear plates, hydraulic cylinders, connecting rod bearings.Even with the most stringent application requirements, our customers can still rely on our high strength, scratch resistance and low friction aluminum alloy bearings.

Application of vane pump self - lubricating bearings & bushings


The rotary vane pump provides hydraulic power for the automatic transmission.
Located on the transmission cover, they pull oil at low pressure from the sump at the bottom of the transmission and feed it at high pressure to the hydraulic system, the gearbox cooler, and the torque converter.
The blade rotor is supported by bearings on the front and rear plates.
When mounted on the backplane, needle roller bearings may fail due to lack of oil, especially after a long rest in different climatic conditions or during repeated start and stop operation.
