Re: Hex Shafts and Bearings
Hey, someone want to contact these folks and find out price/availability/sizes of their hex shaft adapters? Might be a cheap solution.

See middle of page.

Stock Drive Products has round sleeves with a hex hole:

Re: Hex Shafts and Bearings
Small Parts sells hexagonal sleeves, but they aren't cheap.

Re: Hex Shafts and Bearings
Does anyone know where to get a ball bearing with a hex in, like shown on aj's post. I was looking for a mcmaster number.

Thanks in advance.

The Small Parts item appears to have the same properties as the SDP-SI item that Dick linked just above. The SDP-SI item is priced much lower.

AndyMark sells a very nice hex hub for $15 each.

Now if someone would offer hex shafts that are turned down to 0.4995 inch on one end...

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.

Re: Hex Shafts and Bearings
Some sweet poly bearings, but no 1/2 or 3/8 hex sizes:

Re: Hex Shafts and Bearings
If any of you live near a community college that has a machining program, contact them and see if they will help with minor machining, such as rounding off the end of a hex shaft. Our local CC was delighted to help us put several of our #35 sprockets on a diet to save weight. They even gave me the mandrel they made in case we needed to do it again.

I've also had a local machine shop turn down some shafts for free.
