ABSTRACT:
An arrangement for concentrically positioning a first part relative to a second part, for example, a casing, or sleeve, (2) relative to a shaft (1), when the parts are made from materials with different coefficients of thermal expansion, provides a radial clearance (4) between the first and second parts. The first part (2) is supported along its length by portions facing radially away from the second part, at an abutment arrangement (7, 8) having the same or similar thermal expansion characteristics as the first part (2). The abutment arrangement (7, 8) is held concentric relative to the second part (1).
