Vintage Shimano Hyperglide Bearings

Hi... I'm re-furbing a 90's Shimano Hyperglide freewheel (14-28 Singapore) and need to determine the ball bearing sizes for replacement. Can't seem to find a post in search. This one has almost perfect gears and just about zero wobble. No black 28 gear. Almost looks like a new IRD. I know these are cheap but I like this one and I got plenty of time!

Thanks, Bill

When I took one apart without trying I recall they were small like 5/32 and there were very many of them.

I think there is an exact size designation and a bearing grade for these. Metric or American!

In my experience the balls in Shimano, Suntour, and Regina freewheels are all the same size. Specifically, I have not measured them. But when I needed a spare ball or two I simply went to my Ball Bearing kit from Loose Screws and used the smallest balls, which happen to be 1/8s.

L-R: Suntour, Shimano, Shimano



Regina Corsa for comparrison
