Slide Paths PAS bronze bushing material wrapped with POM
(Polyoxymethylene, also known as Acetal or Delrin) lined bushings
offers a unique combination of properties. The bronze bushing
material, typically composed of a high-strength alloy such as
phosphor bronze, provides excellent wear resistance and
load-bearing capacity. The POM lining, on the other hand, offers
low friction coefficients, good chemical resistance, and
dimensional stability.
The combination of these two materials results in bushings that are
suitable for a wide range of applications. The bronze base ensures
durability and stability, while the POM lining reduces friction and
wear, leading to longer service life and smoother operation.
Slide Paths PAS bronze bushings with POM linings are often used in
high-load, high-speed, or precision applications where precise
control of movement and low wear are critical. They are suitable
for a variety of industries, including automotive, machinery, and
industrial automation.
Dry sliding strip of triple-layer POM composite bearing bushings
material
Length 500 × 100 mm thickness 1 to 2,5 mm cut in size made to order
from china.
The strip can be bent, pressed, cut etc. to fit the particular
application. Suitable for space-saving, maintenance-free arrangements of all
types and where there is a risk of moderate contamination or edge
loading. Initial lubrication required.
Wrapped bronze POM SLEEVE bearings are produced from strips that
are subsequently wrapped and calibrated.

of your project situation and strips sizes requirements in the
inquiry. We will efficiently provide you with product selection

Rolling bearing is a kind of rolling bearing, which is made of high
quality cold rolled steel plate, sintered porous spherical bronze
powder in the middle, and then rolled on the surface of porous
spherical bronze powder with modified polyformaldehyde and rolled.
This type of bearing is required to be coated with lubricating
grease during assembly due to its regular surface rolling
arrangement and oil storage holes with helical Angle. It is especially suitable for the occasions where it is difficult
to form fluid lubrication under high load and low speed. The oil
storage holes on the surface can ensure the optimal oil
distribution, and long-term maintenance is unnecessary.
VIIPLUS 20 series POM BUSHINGS has good physical & mechanical properties, also has certainly chemical properties. This material has good
machining performance if required.tri-layer low maintanence plain
bushing have a base of lower carbon steel, onto which a porous
bronze layer is sintered. Acetalcopolyer (POM) is impregnated into the intersice of this bronze layer after
rolling process completed. Lubrication indents are stamped into
this layer.

Wrapped POM Lined Bearings Steel + Bronze Powder + POM Strips
Our POM range of wrapped acetal lined bearings are suitable for
rotary and oscillating movement applications.
The VIIPLUS plain bearings are available in metric and imeprial
sizes as standard.
Our in-house machining service is able to offer non-standard sizes
to suit customer specific requirements.

Characteristics
VIIPLUS range of wrapped POM lined bearings are suitable for rotary and oscillating movement
applications. They benefit from long re-lubrication intervals, no
absorption of water, outstanding damping behaviors and have a low
suceptibility to edge loading.
Strips PAS are available as an even material section. This material
section can be used to make sliding elements in a variety
of shapes.
Metal - Polymer Composite Bearing With POM Material
The VIIPLUS range are ideal for the automotive, machine building and
agricultural industries and indeed any application where lubricant
cannot be supplied continuously
Material Information
- Low-maintenance standard solutions
Plain Bearing Production
Sliding elements in a great variety of designs are produced from
the composite material in cutting, stamping and shaping processes.
Standard designs are:
- Cylindrical bushes
- Thrust washers
- Strips
If these material sections are used to create slide paths, they
have the following main functions:
- Absorbing and transferring forces acting vertically to the running
surface
- Fixing moving components to each other
- Ensuring guidance accuracy for axial movements over the entire
service life
Strips are available in two material groups:
- Material group P1 for maintenance-free, dry-running applications
- Material group P2 for low-maintenance, lubricated applications
For the advantages of each group and help deciding which material
group is best for the relevant use, please refer to the information
provided in the section cylindrical bushes, flange liners and
thrust washers.
VSB-20 Flange liners PAF
- 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
Our wrapped POM lined bearings have a high wear resistance and low
friction even with very small quantities of lubricant
The surface carries a pattern of circular indents which should be
filled with grease on assembly
Low carbon steel gives exceptionally high load carrying capacity
and excellent heat disspation
1. POM thickness 0.30~0.50 mm. It provides high wear resistance 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.
