ABSTRACT:
A magnet coupling system has driving and driven coupling elements, each of which has a magnetic element thereon between which a gap is defined through which a can passes. The magnet coupling system includes a sleeve bearing apparatus comprising a pair of axially spaced sleeve bearings. The sleeve bearing apparatus has a bearing casing enclosing both sleeve bearings and defines a closed fluid flow chamber through which a temperature-control fluid is circulated from an external source. An outer circumference of the bearing casing exchanges heat with an inner circumferential surface of the driven coupling element, and is accommodated substantially-completely within the driven coupling element, to heat or cool the sleeve bearing apparatus and the driven coupling element, and thus the gap between the magnet elements, to a suitable temperature.
