POM (Polyoxymethylene) plain composite bearings, including
bushings, units, housings, and thrust washers, are designed to
provide exceptional wear resistance, low friction, and long-lasting
performance in a wide range of industrial applications.
POM, also known as acetal or polyacetal, is a thermoplastic polymer
that offers excellent mechanical properties, including high
stiffness, good dimensional stability, and low moisture absorption.
These properties make POM an ideal material for composite bearings
that require precision and durability.
POM plain composite bushings are used in various applications where
rotational or linear motion is required. They are often found in
automotive components, machinery, and equipment that requires
smooth and reliable movement. The composite material of POM and
other reinforcements provides excellent wear resistance and low
friction, reducing energy loss and maintenance requirements.
POM plain composite bearing units and housings are designed to
provide a complete bearing solution. These units typically include
the bearing bushings, housing, and any necessary fasteners or
seals. The housings are precision-engineered to ensure proper
alignment and fitment, while the fasteners and seals provide secure
installation and protection against contaminants.
POM thrust washers are used in applications where axial loads need
to be transmitted or supported. They are designed to withstand high
compressive forces and provide a smooth, low-friction interface
between moving parts. POM's high stiffness and low moisture
absorption make it an excellent choice for thrust washers that
require precise and reliable performance.
In summary, POM plain composite bearings, including bushings,
units, housings, and thrust washers, offer a durable and reliable
solution for industrial applications that require precision, low
friction, and excellent wear resistance.

Plates ... VIIPLUS bradn bearing material is known by various names
such as POM-10 or POM10. Buying a sf-1 bearing from VIIPLUS or its
authorized distributors guarantees that you do not receive a
counterfeit product. ...POM coated bearing is a standard item of
our company. This type self-lubricating bushing has same material
structure with other POM bushing. It's also called boundary
lubricating bearing,POM bearing,SF-2 oilless bearing,plain sliding
bearing and dry bushes.
Boundary lubricated lead-free bearing is improved from black
POM.Its performance is the same as the black POM, but the surface
does not contain lead, the use of the field can be extended to
environmental requirements of the field.At present, the product has
been used in imported textile equipment, plunger pump swing
position, automobile joystick position and other medium load,
medium speed, grease lubrication occasions.
Boundary Lubricating Bearing Material Structure
1. POM 0.3~0.5mm.
2. Porous bronze 0.2~0.3mm.
3. Steel backing 0.4~2.2mm.
4. Copper plating 0.008mm.
Characteristics
· Good load capacity & wear-resistant
· Suitable for linear, oscillating and rotating movements
· Optimum performance under relatively high loads and low speeds
· Lead free bushing can meet environment protection requirement

Typical Applications
Self lubricating bearing is widely used in the machine that Lead
free is unacceptable, such as textile machines, auto operating
parts,auto chassis, forging machine, metallurgical and so on.
Office Equipment:Such as printer bushing,Photocopier shredder
bushing,air compressor bushing etc.
Household Applications:such as refrigerator bushing,washing machine
bushing,air conditioner bushing,Fan bushing.tv bushing etc.

Manufacturer
· 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
Suitable for rotating and oscillating movement, less 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 behaviours, good resistance to
shock loads.
Strusture
1. POM thickness 0.30~0.50 mm. It provides high wearresistance and
low friction even with only minute volume oflubricant 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. 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 bearing surfaces.
3. Low-carbon steel.Setting the foundation of the bushings, the
steel back provides exceptional stability,load carrying and heat
dissipation characteristics.
