Matt G. you are right about the pitch on the shaft. All seal surfaces on spinning shafts are plunge ground as not to put a lead in the surface. I machine shafts for a high end gear boxes and lead in the seal surface will cause a seal to leak bad! It will actually pull the oil out of the seal. If its ground stock from Mcmaster then it was ran threw a centerless grinder which means it was ran threw as a spiral and you can probably see it if you hold it in the light just right. Our ruff stock comes in like that and sometimes you can actualy feel the grooves left in the grinding process.
