Product Specification

Our company specializes in the production of POM (Polyoxymethylene) bushings and plain bearings with precise internal clearances specifically designed for valve bushing applications. These bushings and bearings are engineered to provide superior wear resistance, durability, and smooth operation.
POM, a high-performance engineering plastic, offers excellent mechanical properties, including high stiffness, strength, and low friction. Combined with the precision internal clearances, our POM bushings and plain bearings ensure a tight and reliable fit in valve assemblies.
The internal clearances are carefully controlled to allow for thermal expansion and contraction, ensuring a consistent and reliable seal throughout the operating range of the valve. This helps to prevent leakage and maintains the integrity of the valve system.
Our POM bushings and plain bearings are suitable for a wide range of valve bushing applications, including high-pressure and high-temperature environments. They are also resistant to corrosion and chemicals, making them ideal for use in demanding industrial settings.
We pride ourselves on our commitment to quality and customer satisfaction. Our products are manufactured using the latest technologies and rigorous quality control procedures to ensure consistent performance and reliability.

Valve Bushings and Plain Bearings - Clearances.Typically valve bearing & bushes internal clearance is defined as the total distance through which one ring can be moved radially (radial internal clearance) or axially (axial internal clearance) in relation to the other ring under a defined measuring load.

· 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 wear resistance 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.
