This bearing is used as a motor and eccentric bearing for most Thomas 2450AE44 compressors.

The Thomas 2450AE38 and Fasco/Respironics compressors also use this bearing for the eccentric but not all use it as a motor bearing.  The larger bore motor bearing for most newer Thomas 2450AE38 and all Fasco/Respironics compressors can be found here.
