Topic tags/keywords: bandsaw blade guides tool


I have a Craftsman 10” bandsaw, which uses ball bearing blade guides. I have just discovered that the two lower guides are virtually locked up. I suspect that may be due to fine sawdust working into the race and gumming it up. Any thoughts on how to clean and lube these bearings, or will I have to buy new ones?

Try some ZEP 45 I use it on all my router bearings.

I use brake parts cleaner in a spray can.

Check if they are roller skate size because you can buy them by the dozen for dirt cheap

You can usually buy bearings of that size for about $5, from a bearing shop.

My bandsaw had a mixture of both sealed and shielded skateboard bearings when I got it on CL. Some of each type have locked up and need to be replaced. I suspect that the seal may wear out because of the high speed on a bandsaw. Shielded would have less friction, but obviously would allow more dust to get through.

They are cheap enough that I may get some of each and see which type lasts longer.

Thanks to all who have responded to my post! My suspicions have been confirmed that sawdust is the culprit. I have also been able, with your suggestions, to find out where I can get inexpensive sealed replacement bearings. I can’t imagine why Sears wouldn’t put such inexpensive sealed bearings on their bandsaws. Sealed bearings may not last forever, but I’ll bet they last longer than unsealed ones.

High speed? LOL – those will be running as slow as molasses compared to their max ratings.. The typical 608’s and 6200’s are rated for speeds in the tens of thousands RPMs. The only reason shielded bearings (instead of sealed) are used is because they have less rotational friction than their sealed counterparts, which is desirable for that application where there is just a light friction touch between the blade and bearing.
