During installation and storage, ensure that the bushings do not come into contact with absorbent materials, otherwise oil losses will occur quickly. The ideal solution is to store it in its original packaging. In case of oil loss, re-soak by dipping in hot oil (80 °C) and let it cool down in it. Additional lubrication is normally not necessary. However, it can be advantageous under extreme operating conditions.
Hardened and unhardened shaft materials with grinded surfaces can be used. In subordinate applications, drawn shafts can also be used. We recommend roller burnishing or hard chrome plating of the surface when using stainless steel shafts to prevent the abrasive effect of these materials. Shaft tolerance h6 - h9 with bushing tolerance E7
Sintered materials can be machined with carbide (K20/K01) or diamond tools. Cutting speed 100 - 150 m/min. Do not rub or grind sliding surfaces of oil-impregnated bearings, as this will close the oil-promoting pores.
Thanks to our large tool stock, our manufacturing plant can also produce many special sizes in standard (E7 / r7) or special tolerances. Length tolerance of thin-walled bearings t
