Abstract
An arrangement for cooling a spindle bearing or bearings of an abrading apparatus with rotating abrading members is disclosed. This is premised on arranging in a housing of the abrading apparatus conduits which extend from a spindle bearing chamber wall of the housing to an inner suction chamber wall of the housing. Via such conduits, hot air may be expelled from a spindle bearing chamber of the housing as an overpressure in front of a protruding balancer element of a rotating shaft balancer is discharged from the spindle bearing chamber via a conduit into a suction chamber. Cool air may be conveyed from a suction chamber into the spindle bearing chamber as an underpressure behind the protruding balancer element draws in air from the suction chamber via the conduit to the spindle bearing chamber.
