Bushing Online Solution
Professional Manufacture for POM Bushings.
A specific kind of POM (Polyoxymethylene) bushing that’s designed for a variety of applications, from vehicle chassis to machine tools, metallurgical machinery, and hydraulic industry applications. These bushings, with their self-lubricating and boundary lubricating properties, are designed to reduce friction and wear, enhance performance, and prolong the life of machinery.
The structure you mentioned includes:
- Carbon Steel: This forms the backing layer, providing structural strength and rigidity.
- Copper Powder: This layer is typically sintered onto the steel, creating a porous structure that can absorb and retain lubricants.
- POM + Pb (Lead): This forms the sliding layer. POM is chosen for its excellent low-friction properties, and the lead further improves the self-lubricating characteristics of the bushing.
These bushings have excellent anti-abrasion and load capabilities, making them suitable for heavy-duty applications. Moreover, they offer good corrosion resistance, which allows them to be used in environments where they may be exposed to moisture or corrosive substances. Bushings are environmentally friendly and lead-free. This seems to contradict the inclusion of lead (Pb) in the sliding layer. If the product is indeed lead-free, it’s likely that an alternative to lead is used to achieve similar self-lubricating properties.

The POM Series Bushings are made of steel bronze powder with POM and have the following layers: POM 0.30~0.50mm, has high wear resistance and low friction self-lubricating bearings！ POM composite & PTFE composite bearing. Boundary Lubricating Bushings Steel Bronze POM Bearing！A POM bushing used in a truck’s sleeve axle has the primary function of reducing friction and ensuring smooth rotation between the axle and its surrounding components. POM, or Polyoxymethylene, is an engineering thermoplastic that is characterized by its high stiffness, low friction, and excellent dimensional stability, making it an ideal material for bushings.
POM bushings often include small indents or pockets to store lubricants, enhancing their self-lubricating capabilities. The POM layer is typically bonded to a porous bronze sinter, which in turn is bonded to a steel backing. This combination offers excellent load capacity and wear resistance, even under harsh conditions, such as high speeds, oscillating movements, or under heavy loads.

POM bushings
A small amount of lubricant is required for these bushings (All greases or oils designed for lubricating plain bearings). POM bushings have good sliding properties and are suitable for rotary and rocking movements. They have a low coefficient of friction, low sensitivity to edge loading and good damping properties. They can be post-machined. They are low maintenance due to the long relubrication intervals.
This material is designed for semi-dry friction working conditions with limited lubrication. Regularly arranged circular depressions are formed on the sliding surface, which are filled with sufficient lubricant once during assembly. The sliding material consists of polyacetal anchored in porous bronze on a sintered steel substrate.
The POM bimetallic strip has a 0.25 mm thick layer of polyacetal over the bronze interlayer so that it can be machined if required. It has good conformability, hence its resistance to edge pressures, but is not suitable for dry work.
The coefficient of friction is low when initially lubricated with grease and increases thereafter. When the sliding life of the pom bimetallic belt is not sufficient with the initial lubricant supply, it can be increased by repeated relubrication. pom bimetallic belt products have excellent sliding properties.
The operating temperature range is from -40 to +110°C, short term up to +130°C.
The POM bushings are equivalent to the bushings marked PM…,PCM…M, PAP…P20, GLY.AB…, MX…, SF-2…, In a truck’s sleeve axle, these POM bushings can provide benefits like:
Reduced Friction: This is perhaps the most important advantage, as lower friction means less wear on the axle and surrounding components, potentially extending their life.
Smooth Operation: With their low-friction properties, POM bushings can contribute to a smoother, more comfortable ride.
Reduced Noise: By reducing friction and improving the smoothness of operation, these bushings can also reduce the amount of noise produced by the axle.
Maintenance-free: The self-lubricating nature of these bushings means they require little to no maintenance once installed.

Acetal Sleeve Bearings: The Ideal Solution for High-Speed and High-Moisture Environments
Acetal Sleeve Bearings: The Ideal Solution for High-Speed and High-Moisture Environments
Acetal sleeve bearings are a type of self-lubricating bearing made from acetal, a high-performance thermoplastic material known for its excellent wear resistance, low friction coefficient, and high dimensional stability. These bearings are ideal for use in high-speed and high-moisture environments where traditional metal bearings may fail due to corrosion or lack of lubrication.
Acetal sleeve bearings are commonly used in a variety of industrial applications, including food processing equipment, packaging machinery, medical devices, and marine equipment. They are also used in consumer products such as electric fans, power tools, and toys.
One of the key benefits of acetal sleeve bearings is their ability to operate without additional lubrication. The material’s low friction coefficient means that it provides excellent resistance to wear, even in high-speed applications. This feature makes acetal sleeve bearings ideal for applications where frequent lubrication is difficult or impractical.
Another benefit of acetal sleeve bearings is their resistance to moisture and corrosion. The material is highly resistant to moisture absorption, which means that it maintains its dimensional stability even in high-humidity environments. This feature makes acetal sleeve bearings ideal for use in marine applications or other high-moisture environments where traditional metal bearings may corrode or rust.
Acetal sleeve bearings are also known for their quiet operation and smooth performance. The low friction coefficient of the material reduces noise and vibration, making them an ideal choice for applications where noise and vibration are a concern.
In addition to their performance benefits, acetal sleeve bearings are also easy to install and maintain. They can be easily pressed into place and require little to no maintenance over their lifetime.
Different industries have different requirements for bushing materials; for example, some want high temperature resistance, some need corrosion resistance, some need electrical conductivity, some need to operate underwater, etc.; this requires us to use a variety of different materials to achieve the material modification in order to meet the requirements of different working conditions; focus on meeting the requirements of one or several core working conditions.

The sliding bearings you mentioned, POM bushes with lubrication pockets, are a type of self-lubricating bearing that are designed to work well in a wide variety of conditions. They are composed of three layers:
- Steel Back: This is the supporting structure of the bushing, providing rigidity and strength. The steel back helps the bearing withstand heavy loads.
- Porous Bronze Sinter: The bronze layer is created through a sintering process, where the material is heated to a temperature below its melting point until its particles adhere to each other. This creates a porous structure that can hold lubricant, enabling the self-lubricating function of the bearing.
- POM with Lubrication Indents: Polyoxymethylene (POM), also known as acetal, is a type of engineering thermoplastic. In this bushing, it’s used as a sliding layer that provides excellent low friction properties. The POM layer is generally designed with lubrication indents or pockets that store lubricant, providing long-term self-lubrication.
These bushings are made for high-performance applications and are resistant to wear and tear, making them suitable for a variety of industrial applications, including automotive components, agricultural machinery, construction equipment, and more. They offer good load capacity and anti-wear performance, even under harsh conditions such as high speeds or oscillating movements.
