    Rifling Design - Machining Limitations

    I have seen this tried on many levels at different sizes of bore been involved in experimenting and testing of trying to create a swirling flow of fluid with rifled grooves or splines what ever you want to call them the results were always the same. The influence of the outer layer of fluid did...

    No it is not the bearing race it is the backup surface for a kingsbury type thrust bearing from my understanding (again I am just the machinist and not in contact with the whole machine just the parts they bring me.) I am willing to guess that this solder joint is going to be a low temp solder...

    Split Bearing spacer

    This is a 6" dia. plate with a 2 3/4" hole about 3/4" thick it goes behind the thrust bearing to set the thrust clearance of the rotor of a steam turbine. It is split to install around the shaft has to have zero gap in the split when finished so two oversize pieces are soldered or glued together...
