Abstract

A fluid operated linear drive in which on the outer periphery of a centering portion (24) fitting in a housing tube (4) at least one housing cover (5) has an annular groove (28) accommodating an annular seal (32). The outer flank (36), which is on the side of the housing tube (3), of the annular groove (28) is a component of cap part (42), which is coaxially mounted on the centering portion (24) and fixed on the housing cover (5). This division into two parts facilitates production of a flash-free annular groove (28) without fettling.
