Maintenance-free, self lubricating bearing polyacetal Coted Strips
The structure of this prelubricated yellow bushing strip material
consists of spherical powdered bronze sintered onto a steel backing
and polyacetal resin impregnated into the surface.

TOP-20 Strips, Slide paths PAS self lubricating low-maintenance
Wrapped POM Lined Bearings Steel + Bronze Powder + POM(DX) Strips
Our POM range of wrapped acetal lined bearings are suitable for rotary and
oscillating movement applications.
The TOP 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
TOP BEARINGS 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 TOP BEARINGS range are ideal for the automotive, machine building and
agricultural industries and indeed any application where lubricant
cannot be supplied continuously.
Material Information
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.
TOP-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 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 PTFE 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.
