Machining on these is questionable - The tapped hole didn't even appear centered in the cone. These measure .563" thick. The cones from my Puch/Grimeca Snowflakes on my 1978 Free Spirit were .465" thick. So these gave me an incorrect axle stack-up. I ended up exchanging these for the Olympia bearing cones.
