An end block for a magnetron device having a rotatable target comprises an end block housing having a pivot bearing. The end block housing is adapted on its outer side for attachment on a support unit, and the pivot bearing is adapted on an end that is accessible from outside the end block housing, for connection to the rotatable target.
