Abstract: A screw actuator (4) comprises a housing (1), a nut (5) and a screw (6) one of which is axially fixed with respect to the housing and the other of which is axially displaceable with respect to the housing for moving an head (21), as well as a motor (7) which comprises a stator (8) connected to the housing, and a rotor (9) which is drivingly connected to a rotatable part (6) of the screw actuator, the housing having a bore (10) accommodating at least the nut and/or screw, an axially fixed part of said nut or screw being supported with respect to a radial support abutment (11) which extends inwardly in the bore. The rotor of the motor is supported rotatably on a sleeve (13), said sleeve engaging the fixed part and extending away from the brake pad, said sleeve having a radially outwardly extending sleeve flange (14) which is interposed between said support abutment, and the axially fixed part.

Abstract: Computer program product for assisting a user to select among information units of a plurality of structured information units concerning at least one of products, their use and technical solutions in relation to bearings and seals. Each information unit is arranged to comprise the following. 1) An information item comprising information related to at least one of the products, their use and technical solutions in relation to bearings and seals. 2) A descriptor tag indicating the information contents of the information item. 3) A structure tag pointing to at least one information unit in an information unit structure database. 4) A solution category tag pointing to at least one information unit in the information unit structure database and indicating belonging of the information unit to one of design, reliability, maintenance and training categories.
