Plain Bearings

In addition to its metal-polymer composite bearings, Schaeffler Group, has launched its ELGOTEX plain bearings. Each bush comprises two layers of wound (twisted) material. The inner, sliding layer made from synthetic fibers and PTFE fibers in epoxy resin, whilst the outer layer comprises continuous glass fibers (filaments) in epoxy resin. This combined, double wound material is stabilized by applying a specific winding angle to the glass fibers, which significantly increases the strength of the bush. The result is extreme robustness, compactness and low wear (due to consistent friction levels). In addition, the plain bushes are lighter than their bronze equivalents. They are easy to mount and require no further axial location. Due to their dry-running characteristics, the bushes are also environmentally friendly. They are maintenance-free for life, resulting in reduced maintenance costs for the end user. Insensitive to shock loads and edge pressures, the plain bushes are suitable for applications where high radial loads or high static loads are present. Available with integrated seals and resistant to corrosive media, they also perform well in applications where swivel or axial movement is required. The plain bushes with ELGOTEX are available with bore diameters from 20-200mm, outside diameters from 24-220mm, and widths of 15-250mm. Custom versions with outside diameters up to 1,200mm are also possible.
