Low-maintenance and maintenance-free plain bearings
Permaglide® plain bearings- the name Permaglide®, 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 (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.

Material production
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.
Preferred areas of application
1.Maintenance-free operation under dry-running conditions
2.Rotating or oscillating movements
3.Up to a velocity of 2 m/s
4.Linear movements
5.Temperature range -200 °C to 280 °C

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 (Poly 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.
