SAFELY SLIDING AND LIFTING Spieth radial plain bearings - Hydrodynamic multilobe bearings with adjustable play. When it comes to the implementation of spin- dle bearings in modern, powerful machines, roller bearings are increasingly being pushed to their limits and are being replaced by slid- ing bearings. Hydro-dynamically lubricated, adjustable multilobe radial plain bearings manufactured bySpieth play to their strengths in the field of mechanical engineering and in machine tool engineering in particular: They allow heavily loaded spindles to lift away from the bearing surface and float on the lu- bricant layer. This allows the increasing re- quirements in terms of surface quality, dimensional accuracy, manufacturing tole ance of the work piece as well as tool se life to be fulfilled. With the high leve damping achieved by the lubricant film a with their concentricity, they combine sm running with shock resistance and long :

RADIAL PLAIN BEARINGS SPIETH RADIAL PLAIN BEARINGS We'll provide you with the perfect radial plain bearings for your application. We'll also make choosing easy - with expert advice from our The hydro-dynamically lubricated, adjustable multilobe radial plain bearings are used pri- marily in the field of mechanical engineering. Thanks to their out standing damping, concen- tricity and smooth running characteristics along with their long service life, multilobe slide bearings are an excellent choice for mod- ern powerful machines with their ever-in- creasing requirements in terms of surface quality,...

ASSEMBLY EXAMPLES Example 1: Headstock with open housing The adjustable GLM radial plain bearings are mounted directly in the bores of the head- stock.The axial guiding is placed between the GLM, adjusted for correct play and tightened with a Spieth-Locknut against the spindle end. V-rings are used for sealing against oil loss. Example 2: Work piece spindle head with bearing flange sleeve and closed housing In this stable spindle head design, radial guid- ance is achieved using two GLM bearings mounted in the bearing flange sleeve. Axial guidance is provided by a spindle collar, which is located...
