Part Number LM451349DW - LM451310, Tapered Roller Bearings - TDI (Tapered Double Inner) Imperial
larger image
TDI bearings have a one-piece double inner race and two single outer races and are typically supplied complete with an outer race spacer as a pre-set assembly. The bearing can be used at fixed positions on rotation shaft applications. For rotating housing application it can be used to float on the stationary shaft.
