A bearing assembly comprising a centrifugal debris trap for removing contamination debris from lubrication fluid prior to lubrication of the bearing assembly components is provided. Multiple turns for the inductor are created by suitably configuring the copper traces on the printed circuit boards. The result is a high output power semiconductor laser for the wavelengths between 1. By means of the compressed air exiting the openings a body to be pushed onto the printing mandrel is expanded, which facilitates an easy pushing on; with a cutting off of the compressed air supply an optimal seating between the body and the printing mandrel results, which facilitates an optimal processing of the body.
