ABSTRACT:
In an improved roller, a sealing arrangement (9) at either end comprises a metal annular element (11) which is able to shift axially, and which incorporates a smooth, slender frontal rim (14) breasted with the outward-facing frontal surface of the outer race (5) of an adjacent bearing (4). A thrust washer (15) is lodged between a thrust-bracket (7) and metal annular element (11). The surfaces actually breasted in relative rotation are those of the smooth rim (14) and the bearing outer race (5). The disclosed roller seeks to improve on existing types by simplifying and cutting the cost of manufacture, at the same time enhancing performance.
