Metal-Polymer Composite Bearings, specifically those utilizing a hydrodynamic water lubricated sintered bronze journal design, offer a unique combination of properties that are ideal for various industrial applications. These bearings are constructed with a sintered bronze base that is impregnated with a polymer composite material. This composite material provides excellent wear resistance, low friction, and the ability to operate under extreme conditions.
The sintered bronze journal of these bearings is designed to operate with a hydrodynamic lubrication system. This system utilizes water as the lubricant, which is forced through the bearing during operation to create a lubricating film between the rotating journal and the stationary bearing surface. This film significantly reduces friction and wear, extending the bearing's service life.
The metal-polymer composite material used in these bearings combines the strength and durability of metal with the lubricity and wear resistance of polymers. This combination allows the bearings to operate at high speeds and under heavy loads while maintaining low friction and wear rates.
Hydrodynamic water lubricated sintered bronze journal bearings are commonly used in applications such as pumps, turbines, compressors, and other rotating equipment. They are particularly suited for applications where water is readily available as a lubricant and where the equipment operates under high-temperature or corrosive environments.
In summary, metal-polymer composite bearings with a hydrodynamic water lubricated sintered bronze journal design offer a robust and reliable solution for industrial applications requiring high-performance bearings.
Modified PEEK with self lubricating additives for applications where chemicals where chemicals may be utilized.Excellent wear in both wet or dry applications. Available with a bronze substrate for use as chemical pump or valve bushings. Extra thick liner allows for slight modifications for shaft misalignment.
Water-Lubricated Journal Bearings ...Lowering costs and raising service life with no external lubrication and a reduction in maintenance work, everything delivered immediately from stock - that is the core idea and the objective of all viiplus polymer plain bearings.
Self-lubricating bearings are divided into composite self-lubricating bearings, solid mosaic self-lubricating bearing shaft, bimetallic materials
Self-lubricating bearings, special materials, self-lubricating bearings, according to different uses and conditions, use a different self-lubricating bearings.
One of the major categories of solid mosaic self-lubricating bearings (referred to as JDB) is a combination of metal bearing characteristics and characteristics of non-oil lubricated bearings, lubricated by the metal matrix to bear the load, the special formula of solid lubricating material.
It is characterized by high load-bearing capacity, impact resistance, high temperature resistance and self-lubricating ability. It is especially suitable for occasions where it is difficult to lubricate and form oil film, such as heavy load, low speed, reciprocating or swinging, and erosion of water and other acid And erosion. The products have been widely used in metallurgy continuous casting machine, rolling equipment, mining machinery, mold, lifting machinery, textile machinery, wind power generation, shipbuilding, steam turbine, turbine, injection molding machine and equipment production line. Wear resistance is double the normal sleeve.

1.PEEK/ 0.30~0.50mm. It has high wear resistance and low friction even only minute of lubricant are supplied. The bearing surface carries a pattern of circular indents which will be filled with grease on assembly of the bearing.
2.Bronze layer 0.20~0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the layer and conducts the thermal build up away from the bearing surfaces.
3.Steel backing.Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
