I found out that noisy sealed deep ball bearings like the 6203 may only need a little TLC. I had two in a pulley that seemed to be running rough. I took a very fine tipped screwdriver and pried the seal sides out, gave the bearings a good shot of WD-40 from both sides to get rid of the dried grease, hit them with compressed air, then repacked the grease in them. After that, I put the seal sides back in and they are good as new. Not sure what power tools may use that type bearing but if you run onto some that get noisy, before buying new I suggest taking a look at them to see if you can repack them. Only took a few minutes and saves at least 7 to $9 a piece.

For $15 for 2 new bearings and the time and trouble of taking the motor apart I would always buy new.

When we were kids and rode skateboards, ome trick I always did was take a penetrating lube that contained teflon, like Triflow, and spray that with the little tube into all the cracks of the bearings while spinning. After a few seconds you can feel the bearing get faster and sound smoother and work much better. We usually did this to go faster but it always helped the bearings last longer as well.

While this can work, many times the bearing has been damaged and will fail in a much shorter time vs new. Also the seals like to pop out again after being removed. It’s worth a few $ to me to use new bearings

I live in an area where the suppliers don’t carry the item. It’s generally, “oh yeah, I can order them in and have them in two to three days”. So making do with what I have sometimes is the best option. Price isn’t always the deciding factor. Although I try to save when I can.

After cleaning them up, I can tell that they will last for some time to come. It’s worth a try for me.

When you need new, I found Cartney Bearings to be a good source.

+1 when you have a machine torn apart i always replace the bearings not worth the time to redo again for the money.i just put a shelix head in my jointer and ordered it with bearings and im glad because i found the old ones were getting a little rough.

This would be a good option to keep you up and running to finish a project without having to stop and wait for new bearings.

For a jointer, I agree with you on replacing the bearings. I have done the same and certainly would again. There are other applications like that as well.

Thats great to keep you running till you find replacements. But if a bearing has gone dry or the grease is hardening up from contamination the seals leak and the bearing is probably scored which will kill the bearing sooner than later.

Have your say...
