Product Description

The Metal-Polymer Bearings POM Bushing, made from Polyoxymethylene (POM) or also known as Acetal, is a high-performance bushing that offers exceptional properties such as wear resistance, rigidity, dimensional stability, and good fatigue strength. POM bushings are commonly used in applications where precision, durability, and low friction are critical.

POM, as a material, has excellent mechanical properties and is resistant to many chemicals, solvents, and fuels. This makes it suitable for use in a wide range of industries, including automotive, machinery, and electronics.

Metal-Polymer Bearings, as a manufacturer, is renowned for its high-quality products and precision engineering. Metal-Polymer Bearings POM bushings are precision-manufactured to ensure accurate fits and smooth operation. They are often used in bearings, slides, and other moving parts where low friction and long-lasting performance are essential.

The combination of POM's material properties and Metal-Polymer Bearings's manufacturing expertise results in a bushing that is reliable, durable, and able to withstand the rigors of demanding applications. Whether it's a high-speed machinery component or a precision-engineered bearing, Metal-Polymer Bearings POM bushings are a trusted choice for ensuring smooth and efficient operation.

 

Metal-Polymer Bearings POM Bushing type available in standard dimensions, Cylindrical bushes, flange pom bushing, split steel-backed bushes, and Composite Thrust washers made to order from china.

Tribology solution in the field of Automotive water pump & valve :

Sliding layer POM bushing with or without lubricant indents for machining

Characteristics

 

  • POM 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

 

Structures

 

1.POM thickness 0.30~0.50 mm, it provides high wear resistance and low friction even with only minute volume of lubricant 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, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the resin mixture.
3. Low-carbon steel, provides exceptionally high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.

 

Typical Applications

 

Recommended for applications involving intermittent operation or boundary lubrication...
Automotive: suspension joints, kingpin assemblies and stub axles of tucks, automobile driving joint hinges, steering and other linkages, articulation joints, rear chassis hinges, fair leader rollers...
Machine tool building industry: spindles in drill, grinding, and milling machines, ram guide plates in multi-ram presses...
Agricultural equipment: gearbox, clutch, bale trips and wheel caster swivels for bale accumulators, front axle pivot bearings, steering idler box bearings and kingpin bearings for harvesters... It is especially well-suited for applications where lubricant can not be supplied continuously or repeatedly.

 

Self-lubricating sleeve bearing POM bearing


High load capacity
Excellent impact resistance and self-centering performance
Excellent anti-pollution performance
Good friction and wear resistance
Good resistance to chemical corrosion
Good dry friction performance

 

Product Description

 

POM is a triple layer bearing consisting of a copperplated steel frame, a middle layer of sintered bronze, and a self-lubricating sleeve bearing surface of acetal plastic (POM).
The self-lubricating sleeve bearing surface is provided with grease pockets which embeds the lubricant for gradual
release during operation. The slip layer also has a good ability to embed dirt and small particles that could damage the shaft. POM can withstand relatively high loads and is suitable for rotary and oscillating movements and structures with frequent starts and stops.

Assembly


POM self-lubricating sleeve bearing are not to be worked on (no bore or grinding). Nor on the inside or the outside diameter. They are already prepared for assembly. The bearings are so designed that when press-fitting the bearing into the housing, the mating gap can be eliminated. However, the mating-point of the self-lubricating sleeve bearing should be positioned away from the load-zone.

 


Cutting or sticking


Always cut or stick the sliding plate (sheets or washers) from the sliding surface towards the steel surface. self-lubricating sleeve bearing is to be cut from the inside towards the outside. This is to prevent the three layers from dividing. Therefore always start from the soft layer towards the harder layer.
It also helps you to keep any burrs in the right direction (not towards the sliding surface).
Please don´t hesitate to contact us if further information is needed.

 

Lubrication


self-lubricating sleeve bearing, washers, or sheets of the brand POM-self-lubricating sleeve bearing are pre-lubricated, and therefore lubrication through grease or oil is to recommend. Through adding oil-resin into the POM-mix, our POM-steel sleeve bearing bushings are actually capable of running a while ”dry”, without breaking. Any type of grease, oil, or another lubricant can be used since the POM layer is not sensitive in any way for the chemical reaction of additives in lubricants.

VSB-20 Boundary  self-lubricating sleeve bearing  High-Quality  POM Bush China Manufacturer


· marginally self-lubricating sleeve bearing  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
 

Typical Applications

 

Suitable for rotating and oscillating movement, fewer 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 behaviors, good resistance to shock loads.

 

It is recommended to be used for initial grease self-lubricating sleeve bearing. This material has good wear resistance and can be used under medium and high load, impact and dust resistance conditions. Such as truck or commercial vehicle axle, brake, suspension system, as well as agricultural machinery, forest machinery, logistics equipment, and other general industrial plain bearings, can replace the general copper sleeve, steel sleeve.

 

Structure

 

1. POM thickness 0.30~0.50 mm. It provides high wear resistance and low friction even with the only minute volume of lubricant are supplied, this self-lubricating sleeve 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 self-lubricating sleeve bearing surfaces.


3. Low-carbon steel.Setting the foundation of the self-lubricating sleeve bearing, the steel back provides exceptional stability, load carrying, and heat dissipation characteristics.
