Fluid-actuated linear drive, has fixing projection cutting out radially and projecting between front side of housing tube and housing lid-covers with respect to axially and permanently placed fixing of damping unit of housing

摘要

The drive (1) has a ring shaped damping unit (46) including a ring shaped damping gasket (33) in a region of an inner circumference and a centering attachment (48) in a region of an outer circumference of the unit. A ring-shaped fixing section (52) axially overlaps the centering attachment without any radial rear cuts. A fixing projection (54) cuts out radially, and projects between front sides (12, 13) of a housing tube (6) and housing lid-covers (4, 5) with respect to axially and permanently placed fixing of a damping unit (46) of a housing (2). A sealant is made of nitrile rubber. The damping gasket is made from an elastic material and poly urethane plastic material.
