Description
Overview:
The Main Bearing 020 Pair for Lister HR engines is a genuine Lister Petter component designed to support the crankshaft and maintain consistent oil film under load. Supplied to OEM specification 351 50260/020, this pair of half-shell bearings suits crankshafts reground to 0.020 in undersize (approximately 0.51 mm). The shells are made from durable, engine-grade bearing materials on a strong steel backing for stable seating and long service life. Fitted in the main bearing housings of Lister HR diesel engines, they help reduce friction, maintain oil pressure, and promote smooth, reliable running. Ideal for rebuilds, servicing, and preventative maintenance in industrial and agricultural applications. This is unused old stock vintage inventory and may show light tarnish or storage marks that do not affect performance.
