<p>Journal bearings comprising two half bearings (13,14) are described. Only one half bearing (13), in the highest loaded position, has an overlay coating (18). Preferably the non-overlay coated half (14) comprises a silicon containing aluminium alloy (21) which exerts a polishing action on the shaft journal thus decreasing the degree of abrasiveness of the journal. The non-overlay coated half (14) may also be profiled to allow accelerated polishing of the shaft journal.</p> |
