Orange metal-polymer bearings, specifically designed for pumps, are self-lubricating sleeve bearings that incorporate tin or copper plating to enhance their durability and performance. These bearings offer exceptional wear resistance, low friction, and superior chemical stability, making them ideal for use in pumps and other rotating machinery.

The combination of (Polytetrafluoroethylene) and metal plating provides a unique material solution that offers the best of both worlds. is renowned for its low coefficient of friction and excellent lubricity, while the metal plating adds strength, durability, and corrosion resistance.

The tin or copper plating on the sleeve bearing surface creates a smooth and hardwearing surface that resists wear and abrasion. This ensures that the bearing maintains its performance over extended periods of operation, even under high loads and speeds.

The self-lubricating properties of the Orange metal-polymer bearings eliminate the need for external lubricants. This not only reduces maintenance requirements but also eliminates the risk of contamination from lubricants, which can be problematic in pump applications.

Overall, Orange metal-polymer bearings with tin/copper plating are an excellent choice for pumps and other rotating machinery. They offer superior performance, durability, and reliability, ensuring smooth and efficient operation of your equipment.

Structure Characteristics

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.

The structure of this prelubricated bearing consists of spherical powdered bronze sintered onto a steel backing and Orange color impregnated into the surface.
 

Metal-polymer marginal lubricating composite materials consist of metal backing sintered porous bronze with POM or PEEK polymer as working layer. Steel backing provides exceptionally high load carrying capacity, excellent heat dissipation. Sintered bronze powder provides thermal conductivity away from the bearing surface, also serves as a reservoir for the resin mixture.And the POM or PEEK polymer layer provides high wear resistance and low friction even with only minute volume of lubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.

Detailed information

Boundary lubrication lead-free bearing is improved on the basis of VSB-20. It has the same performance as the VSB-20, but the surface does not contain lead, and the field of use can be extended to areas with environmental requirements.

VSB-20 Boundary lubrication bearing High Quality  POM Bush China Manufacturer
· marginally lubricated bushings for grease or oil lubricated applications
· Standard parts contain grease indents in the sliding layer; plain sliding layer available by request
· Optimum performance under relatively high loads and low speeds
· Suitable for linear, oscillating and rotating movements
· Wide range of parts available from stock
 
Suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.

1. POM thickness 0.30~0.50 mm. It provides high wearresistance and low friction even with only minute volume oflubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.

2. Sintered bronze powder thickness 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. Low-carbon steel.Setting the foundation of the bushings, the steel back provides exceptional stability,load carrying and heat dissipation characteristics.
