Product Description: POM is a multilayer bearing consisting of a copper-plated steel frame, an intermediate layer of sintered bronze, and an inner glide layer of acetal resin. The bearing includes lubrication pockets that gradually release lubricant during operation.

The glide layer also effectively integrates dirt and small particles that could otherwise damage the shaft. POM bearings can withstand relatively high loads and are suitable for rotating and oscillating movements, as well as structures with frequent starts and stops.

Installation: POM bearings are prefabricated. When pressing the bearing into the housing, the gap in the bearing is eliminated.

Lubrication: POM layers are primarily designed to be used with lubrication. Lubrication pockets should be filled with appropriate grease before shaft installation to minimize shaft maintenance. Most common greases can be used, but avoid lubricants containing molybdenum disulfide or graphite.

Custom Sizes: Available upon request.

The Boundary Lubrication POM Bushing is a specialized metal-polymer plain bearing designed for operation in conditions where lubrication is minimal. These bearings are engineered to perform optimally even with scarce lubricant, serving as an intermediary solution between fully lubricated and completely dry sliding bearings. “POM” denotes Polyoxymethylene, a thermoplastic renowned for its robust stiffness, minimal friction, superior wear resistance, and consistent shape. The construction of POM bushings features a metallic base for enhanced structural integrity, a sintered bronze layer to foster stronger bonding and evenly distribute load, and a POM surface layer, often pre-treated with lubrication pockets or indentations to boost sliding efficiency and wear resistance.

Offered in a variety of styles, such as cylindrical bushes for radial loads and thrust washers for axial pressures, these bearings are adaptable to numerous load scenarios and applications. Their design flexibility allows for customization through specific dimensions, shapes, and additional elements like lubrication channels, catering to diverse industrial needs.

POM bushings excel in scenarios requiring high performance under boundary lubrication conditions—where the lubricant layer is insufficient to entirely separate the contact surfaces. This capability makes them invaluable in sectors like agriculture, construction, and mechanical engineering, where they find use in gearboxes, pivot joints, and linkage systems, among other essential machinery components.

Incorporating the latest in tribology, the study of friction, wear, and lubrication, POM bushings are crafted to deliver outstanding low-friction and wear-resistant characteristics. They are designed for either dry use or with supplemental lubrication, offering versatility in maintenance and usage. The synergy of metal and polymer in these bearings provides a combination of low-wear operation, high load capacity, and effective heat dissipation, positioning them as an effective solution for diminishing friction and wear in mechanical systems.

In essence, Boundary Lubrication POM Bushings epitomize an advanced category of metal-polymer plain bearings, tailored for limited lubrication scenarios. Their structural and material design ensures a mix of high efficiency, longevity, and adaptability, rendering them ideal for a broad spectrum of industrial applications.

SLIDE BEARING BUSHING2

Designed for the marginal lubricating bushing. It is backed with copper-plated steel with porous bronze sintered on it and polymers (POM) embedded into the bores of the bronze. The steel back provides the products with high-quality low-carbon steel. Oil dents stamped on the surface of the polymer can achieve good lubrication between the bushing and its mating axis. It is of good anti-abrasion and load capability. The plating coating on the surface is erosion-protective. It is environmentally protective as no lead is included in the surface polymer POM. Products of the POM series are widely used on automotive chassis, forging machines, mine quarrying machines, metal smelting, and casting machines, and in water irrigating and steel rolling industries.
