TDI (Two-Row Double Inner Race)

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. TDI bearings are sometimes used on rotating shaft applications where a loose fit is required for ease of removal.
