Double row bearings offer nearly twice the capacity of the equivalent single row bearing, and are therefore used in more heavily loaded applications. The plain outer race enables this bearing to be used in a ‘floating’ position to permit thermal expansion. As such it can replace a P type bearing when additional load capacity is required. G type bearings can be preadjusted to give GE double row bearings. This is achieved by fitting a spacer between the inner races to give the required assembly end play or preload. Spacer width is adjusted individually prior to despatch.
