Polymer bushings, also known as plastic bushings, are components used to reduce friction and wear in mechanical systems. They are typically made from materials such as nylon, PTFE, UHMW, and other high-performance polymers.
One of the main benefits of polymer bushings is their ability to resist corrosion and chemical attack, making them ideal for use in harsh environments. They also have excellent wear resistance and can withstand high loads, making them ideal for use in heavy-duty applications.
Another advantage of polymer bushings is their ability to dampen vibrations and reduce noise, making them useful in applications where noise and vibration are a concern. Additionally, polymer bushings are lightweight and easy to install, making them a cost-effective alternative to traditional metal bushings.
When selecting a polymer bushing, it’s important to consider factors such as load capacity, temperature range, chemical resistance, and other application-specific requirements. POm bushings, also known as “double-collared bushings,” are a type of polymer bushing commonly used in automotive and industrial applications.
To determine the appropriate size of POm bushing for your application, you can consult a pom bushing size chart, which provides information on the bushing’s inner and outer diameter, as well as the length of the collar. It’s important to choose the correct size bushing to ensure optimal performance and longevity of your equipment.
Polymer bushings, also known as plastic bushings, are a type of plain bearing that is made from various thermoplastic materials, such as POM (Polyoxymethylene), PA (Polyamide), and PTFE (Polytetrafluoroethylene). These materials offer several benefits over traditional steel or bronze bushings, including improved wear resistance, low friction, and reduced noise. In this article, we will discuss the benefits and applications of polymer bushings.
Benefits of Polymer Bushings
- Improved wear resistance: Polymer bushings offer excellent wear resistance due to the low coefficient of friction between the bearing surface and the shaft. This results in longer service life and reduced maintenance requirements.
- Low friction: These bearings have a low coefficient of friction, which reduces energy consumption and heat generation, resulting in improved efficiency and reduced operating costs.
- Reduced noise: Polymer bushings generate less noise than traditional steel or bronze bushings, making them suitable for use in applications where noise reduction is critical.
- Chemical resistance: Polymer bushings offer excellent chemical resistance, making them ideal for use in corrosive environments.
Applications of Polymer Bushings
- Automotive industry: Polymer bushings are commonly used in various automotive applications, including suspension systems, steering systems, and brake systems.
- Industrial machinery: These bearings are suitable for use in various industrial machinery, including pumps, compressors, and machine tools.
- Medical equipment: Polymer bushings are ideal for use in medical equipment, where low noise, chemical resistance, and biocompatibility are essential.
- Food and beverage industry: These bearings are suitable for use in the food and beverage industry, where FDA compliance and resistance to chemicals and high temperatures are crucial.
Polymer bushings offer several benefits over traditional steel or bronze bushings, including improved wear resistance, low friction, reduced noise, and chemical resistance. These bearings are suitable for use in various industries, including automotive, industrial machinery, medical equipment, and food and beverage. If you’re considering using polymer bushings in your application, it’s essential to consult with a bearing expert to ensure proper selection and installation for optimum performance and longevity.
Metal-Polymer Self-lubricating and Maintenance-free Bearing Solutions, Sliding Bush Supplier, pom bushing sizes chart, flange bushings by size. We’ve had an excellent experience with pom bearings replacement.
POM bushings are made from a steel plate, where the MoS2 is sintered onto the surface, using a bronze powder intermediate layer as a bonding agent. These raw material plates are then cut to a rectangular shape, then wrapped and calibrated to the right size.
The sizes are according to DIN 1494/ ISO 3547 with tolerances to be press-fitted into an H7 housing for an h8 shaft tolerance.
MoS2 is a friction modifier and is often used in heavy-duty greases for its good resistance to compression. However, POM Bushing is not completely maintenance-free, as periodical greasing is still necessary. Hence, the sliding layer is perforated with lubrication pockets.
POM bushing is often used in cranes, truck cranes, tailgates, harbor equipment and agricultural machinery, and construction machines.

Boundary lubricated lead-free bearings
Boundary lubricated lead-free bearings are modified from the matrix of the POM bushes. Its performance is the same as that of the POM bushes, but the surface does not contain lead, and its use can be extended to areas with environmental requirements. At present, the product has been used in imported textile equipment, plunger pump swing parts, auto parts, and another medium load, medium speed, grease lubrication occasions.
Polymer bushings are used in a lot of different situations.VIIPLUS offers a full range of plain cylindrical bushings size in accordance with ISO 3547 and DIN 1494, as well as thrust washers and strips.
POM Composite is referred to as pre-lubricated because it requires only a trace of lubricant to operate satisfactorily for long periods. The material is designed to operate with marginal lubrication and effectively fills the gap between fully lubricated bearings and dry sliding bearings.
They can be a plain polymer ( such as blue, red, yellow) or layered with a mesh of PTFE and a structure with epoxy resin and glass fiber.
POM Composite sliding bearings are suited for low-maintenance applications in tough running conditions. As a result of the lubricant retention pockets on the sliding surface, VIIPLUS POM Composite bearings are especially well suited for applications in dirty environments where lubricant cannot be supplied continuously or frequently.

Composite Bushing Bearing Application: Mining Hoist
Having successfully used self-lubricating pom bearings in critical brake applications, we now use them extensively on other assemblies where pins are heavily loaded as well. We’ve had an excellent experience with POM bushes industrial sleeve bearings. Compared with the total cost of a hoisting system, they’re a relatively inexpensive component. Something would have to change dramatically for us to consider another bearing.
