DX Bearing
In addition to metric POM bushing products of non-standard bearings. We can also develop according to customers’ special requests while out of this table.
POM bushes are used in a wide range of industries, including agriculture, civil, mechanical, and construction. They are particularly beneficial in situations that demand high stiffness, low friction, excellent wear properties, and significant dimensional stability. Common applications include gearbox assemblies, pivot points, linkage mechanisms, steering systems, and suspension systems
Boundary lubrication bushing
POM (Polyoxymethylene), also known as Acetal, is a high-performance engineering plastic used in the manufacture of precision parts that require low friction and excellent dimensional stability. POM cylindrical bushes are widely used in various industries due to their versatile properties, including automotive applications, industrial machinery, home appliances, electronic parts, and more.
Properties and Applications
- Low Friction and Durability: POM bushes are notable for their low friction characteristics, enhancing the efficiency and longevity of their performance.
- Robust Mechanical Strength: With the ability to retain their properties across a broad temperature spectrum, POM bushes are versatile for various conditions and uses.
- Self-Lubricating: Often supplied pre-lubricated, POM bushes minimize the necessity for further lubrication and upkeep.
- Noise and Vibration Mitigation: These bushes are adept at reducing machinery noise and vibration, facilitating smoother operations.
- High Load Capacity: Despite their streamlined design, POM bushes are capable of supporting substantial loads.
Manufacturing and Customization
POM bushes are commonly produced via precision machining processes such as CNC and automatic lathe work, tailored to the bushing’s specific application requirements. This process includes material selection, design specification, and precise machining to achieve the desired internal diameter, tolerances, and surface quality. Customization options are available, allowing for adjustments in dimensions and the addition of features like grooves or chamfers for specific applications.
Availability and Forms
Available in a wide range of standard sizes, both metric and imperial, POM bushes come in various forms including cylindrical bushes, half-bushings, and specially shaped versions created through stamping or deep drawing. These bushes are well-suited for oscillating, rotating, and linear movements under radial loads.
Industry Use
POM bushes are integral to numerous sectors such as agriculture, civil engineering, mechanical fields, and construction, offering solutions where high stiffness, low friction, superior wear resistance, and excellent dimensional stability are required. They are commonly found in gearbox assemblies, pivot points, linkage systems, steering mechanisms, and suspension systems, showcasing their wide applicability and effectiveness in demanding applications.
This is a steel-based, sintered bronze spherical powder as interlayer and overlaid by a layer of POM, the surface of which is provided with oil indentations.
The thickness of the plastics layer is about 0.5mm.
A trace of oil or grease may be utilized and may work successfully under heavy load with oscillating motion and those which start and stop frequently under load.
Moreover, it is of low cost and long life. This kind of material is now widely used as bushes in chassis of automobiles, forging presses, metallurgical and mining machines, civil engineering machines, hydroelectric industrial machines and steel strip cold rolling machines.
It is a lead-free product.
Marginally lubricated bushings for grease or oil lubricated applications · Standard parts contain grease indents in the sliding layer.
Carbon Steel + Copper Powder + POM
It’s used in vehicle chassis, forming machine tools, steel metallurgical machinery, mineral mountain machinery, hydraulic industry and rolling steel industry, etc.
