This bearing is used as a motor and eccentric bearing for most Thomas 2450AE44 model pumps.
This is for a set of 4 bearings.
The 2450AE38 and Fasco / Respironics compressors also use this bearing for the eccentric but not all use it as a motor bearing.
We have the larger bore bearing for the 2450AE38 in our store as well.
