Abstract

A shaft bearing system having a housing including a spherical collar for the shaft. The shaft bearing is made up of a cage (19) into which the spherical collar (20) is inserted. The cage is installed in a recess (18) in a housing (16); a sleeve (21) is arranged in the interior of the spherical collar, and an axle stub (22) is inserted into the shaft bearing. The rotational movement preferably takes place between the sleeve (21) and the axle stub (22). The use of the spherical collar in a shaft bearing made up of a cage and a guide bushing has the advantage of greater flexibility in selecting the material or materials from which the housing and the rotatable component installed therein may be formed. The shaft bearing of the invention is particularly useful for accommodating a centrifuge rotor (10) in a centrifuge housing (16).
