SHO S/C Duplex bearing
Okay, got the bearing today.
However, the face of one end has slots machined into it.
I assume this should be the front towards the impeller???

Verified: Grooved end goes towards the thrust plate (front).

can someone please fill me in on the benefit of these bearings
(is this the same issue, different solution, that Ross posted on?)

Stock Class and Modified closed course and endurance competition engines with superchargers set up and running higher boost pressures and higher rpm frequencies will eventually need bearing servicing. When the main bearings in the supercharger wear over time, the shaft to bearing tolerance or clearances will become loose and the risk of friction burning or galling the thrust bearing assembly can occur. Servicing the supercharger main bearings periodically or upgrading to R&D’s new “Duplex Bearing System” will extend the life of the superchargers thrust bearing significantly. When supercharger thrust bearing failures have occurred in the past, there has not been a repair option due to no replacement parts manufactured.
