Known for their continuous, low wear sliding characteristics, the Schaeffler Group’s Permaglide range of plain bearings is celebrating its 25th Anniversary this year. These plain bearings offer low wear sliding characteristics, high load carrying capacities and heat dissipation properties that are normally associated with metals. The bearings are maintenance-free and so are ideal for special automotive and general industrial applications.
Permaglide bearings have a porous bronze-sintered structure, applied to a steel or bronze backing, impregnated with the appropriate polymer-mix. This solid lubricant produces a film between the sliding surfaces, which provides low-noise operation at constant speeds and low coefficients of friction throughout the entire service life of the bearing. The bearings are a low cost alternative for applications with comparatively low surface loads and where space is restricted.
The bearings are available in the form of bushes, flanged bushes, thrust washers and strips. Custom-designed versions are also possible, including blanked parts; ball cups; bearing shells; bushes with windows and holes; and bushes with stamped oil grooves. Bush outside diameters are possible from 3mm up to 305mm (in special cases up to 800mm); strip widths up to 250mm; and wall thicknesses from 0.5mm up to 3.06mm.
