MAIN ADVANTAGES
Maintenance-free self-lubricated:
PBC compounds lubricants in balanced ratios into the polymer
matrix and ensure through fiberate mi cro-wear during running
in for clean and continuous auto lubrication. During micro-wear
a transfer coating is built enabling optimal sliding performance.
The basic polymers and their additives already own good
tribological properties.
Long service life:
The homogeneous structure of the compound plane bearings
prevent thin run or wear layers which would shorten service
life right from the beginning. The basic polymer with its mainly
synthetic reinforcement additives forms an intimate matrix
for other additives. There is no abrasive wear of the shafts
because the commonly used glass fibers have been removed.
Low friction:
Static and dynamic coefficients of friction are close to each
other due to the high amount of PTFE and other special
additives in the compounds. Thus, we ensure stick-slip-free
running at lower speeds. The plane bearing also runs with
much less noise. The frictional behavior of the compound
plane bearings depends mainly on tempe rature, sliding
speeds, types of movement and loads. Surface structure
and the circumstances of dry running or greasing standards
substantially influence frictional behavior. Through the
appropriate lubrication the coefficient of friction can be
reduced even further.
High dimensional stability:
All compound plane bearings take in virtually no water, which
can be disregarded to dimensional accuracy in connection
with the installation. Fiber strengthening reduces thermal
expansion/contraction and improves the press-fit at higher
temperatures.
PLANE BEARINGS FOR ALL APPLICATIONS
Standard Plane Bearings:
Standard bearings are stocked in compounds
A and E:
• Bushings
• Flanged bushings
• Thrust washers
• Bushings with integral seals
You can select exact dimensions from the separate
dimension table.
Minimal wear:
Compound plane bearings are extremely wear resistant in
rotating and axial bearings as well as in hinge move ments
under high loads.
High loading capacity:
Our compound plane bearings can withstand immense forces
and pressures. As well as edge loads, which do not cause
problems in contrast to common plane bearings made of
non-fer rous metals or composite materials. Depending on the
compound chosen, high pressures are also permissible.
Broad temperature range:
Depending on the material temperatures of -200°C/-328°F up
to +250 °C can be withstood during application. Always check
the compound specifications in each application with regard
to temperature tolerances.
Improved thermal conductivity:
Polymer compound plane bearings show an improved thermal
conductivity. Higher rpm/sfm during continuous operation are
possible thanks to a better press-fit of the plane bearing in its
housing. This is achieved through fiber strengthening.
Pacifi c Bearing produces compound plane bearings through an injection molding process.
We can help you select a suitable material for a specific application from our wide range of materials. Our technical staff will support
you at every step of the way. PBC will find the best compound for your application – with regard to costs as well as effectiveness/
performance.
Whether you are looking for standard parts or custom/proprietary components we can provide standard plane bearings. Special
components and seals are available as well.
Plane Bearings with Integral Seals:
Plane bearings with integral seals have proven superior in
sustaining the basic advantages of our compound plane
bearings even in tough environments.
The advantages:
• Integral seals keep away dirt and water from the bearing
• Initial lubrication is suggested
• Safe from corrosion
As a standard we provide bearings with double-sided
integral seals.
