Metal-polymer plain bearings, consisting of a steel backing, a porous bronze sinter layer, and a (Polytetrafluoroethylene) lining, represent a robust and high-performance bearing solution for a wide range of industrial applications. This composite design offers numerous advantages that make it a preferred choice for many engineers and designers.

The steel backing provides the structural rigidity and stability needed for heavy-duty applications. It resists deformation under high loads and pressures, ensuring the bearing maintains its shape and dimensional accuracy over time.

The porous bronze sinter layer serves as an intermediate between the steel backing and the lining. It is a porous metal structure that allows for the impregnation of lubricants, such as oil or grease, creating a self-lubricating surface. This layer provides excellent wear resistance and load-bearing capabilities while reducing friction and heat generation.

The lining is the key friction-reducing component of the bearing. is known for its excellent slip properties, low coefficient of friction, and chemical resistance. It creates a smooth, non-stick surface that allows for efficient and reliable rotation or sliding motion. The lining is bonded to the porous bronze sinter layer, ensuring a strong and durable connection.

The combination of steel backing, porous bronze sinter layer, and lining results in a bearing that is highly resistant to wear, corrosion, and chemical attack. It can operate in a wide range of temperatures and environments, making it suitable for a diverse set of applications. The self-lubricating properties of the porous bronze sinter layer further enhance the durability and reliability of the bearing, reducing the need for frequent maintenance or relubrication.

In summary, metal-polymer plain bearings with steel backing, porous bronze sinter layer, and lining offer a robust and high-performance bearing solution for a wide range of industrial applications. Their excellent wear resistance, low friction, and self-lubricating properties make them a preferred choice for many demanding applications.

Composite Self-Lubricating Bushings - Lubrication Free Bushing

composite flanged bushing maintenance-free steel backing

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

• The -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.

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.

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.
