plain bearings- embodies the principle of permanently low-wear gliding.
The use of plastic on a metallic base material has created a material combination that unites excellent
gliding properties with the load carrying capacity and heat
conductivity of metal. The use of solid lubricants in the plastic matrix allows operation
without oil or grease lubrication – these are Permaglide® plain
bearings in material group P1, incl. P10. It is not always possible to accomplish the tasks of a plain
bearing application with products made from maintenance-free
materials, however. In such cases, low-maintenance P2 materials are available.
Depending upon customer requirements and specific applications, a number of maintenance-free and lowmaintenance materials are available with identical microstructure. A porous bronze sinter structure applied to a steel or bronze back and is impregnated with the respective plastic mix. The solid lubricant produces a film between the sliding surfaces. It attributes to low-noise operation at constant speeds and low coefficients of friction throughout the entire service life of the component. This is achieved by means of a mixture of PTFE (Poly Tetra Fluoro Ethylene) with wear-retardant and thermally conductive additives.
It is not possible to find the desired solution for plain bearing applications with products made of maintenance-free materials for all duties and applications. For such duties and applications, low-maintenance materials are available. In this case, the sliding surfacetaking up the wear load is formulated from a PVDF (Polyvinylidene Fluoride) matrix.
Gleitlager Permaglide PAP Buchsen Equivalent is a leaded, robust sliding material with maximum tribological performance. It is designed for maintenance-free, dry-running applications, but can also be employed in systems with liquid lubrication.
The unique features:
The solid lubricant mass is produced in a specially adapted mixing
process. In a parallel, continuous sintering operation, bronze
powder is sintered onto the steel or bronze back as a sliding
layer. This produces a sliding layer with a thickness from 0.2 mm
to 0.35 mm and a pore volume of approx. 30 %. Next, the cavities
are filled with solid lubricant by means of impregnating rollers.
This process step is controlled in such a way that a running-in
layer of solid lubricant up to max. 0.03 mm thick is produced above
the sliding layer. In further thermal treatments, the
characteristic properties of the material system are adjusted, and
the required thickness tolerances of the composite material are
produced using controlled roller pairs.

To reduce the coefficient of friction and improve thermal
conductivity, special additives are mixed into the matrix. In addition, the
surface of the sliding layer may optionally be equipped with lube
bore relieves to accommodate grease or oil.
For Permaglide®, bearings for extremely high performance
requirements, has formulated and applied a PEEK (Polyether Ether
Ketone) plastic matrix that is compounded with special nano-scaled
fillers to improve its tribological properties.
Similar to engine bearings, increasing technical demands and
minimized installation clearance determine the development efforts
for Permaglide® bearings. In accordance with customer requirements,
not only are the geometries and shapes selectively developed but
are optimised as sliding surface systems where purpose-adjusted
kinetic momentum of the sliding pairs are taken into account.
Moreover, customers need not adapt design of their assemblies to
the sliding element; the Permaglide®-bearing optimally adjusts to
the assembly design.
