A centraliser (1) is used for passing assemblies and tools through bores and tubular ducts in a centralised condition, espe- cially in downhole operations in oil work. The centraliser comprises a body (2) including carrying means (3) pivotally supporting swinging arms (4) for effecting centralisation. Each arm (4) is pivotally located (14) at one end while a roller (15) or other imple- ment is carried at or adjacent the other free end. Actuating means (6, 5) including force means (7), such as a spring, load the swung-out arms (4) so that the arms (4) act against the force means (7) when pushed inwardly. The arms (4) are preferably located tangentially on the carrying means (3) and an adjuster (8) for the force means (7) can be provided.
