My Cuisinart CSB-75 Stick Blender has performed well for 2 yrs. Lately it has slowed down & heated near the bearing. Is there a way to lubricate the cutter bearing??
Is this a good question?

jarmush, If you are talking about the bearing in the blender shaft assembly, it will be sealed/non greaseable for food safety reasons and new part is available to change. Below is a guide on how to change the blade/shaft assy., and a couple links to possible replacement part which you can also do a search for better pricing perhaps. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.

Richard, I did a search on the bearing/blender shaft seizing up and found this page. I had already tried what you suggested (I have worked with small and large electronics for years) and it didn’t help at all. Pretty disappointing. There’s nothing wrong with the motor housing or motor itself, though if one would continue to use it with the bad bearing, it will surely chew up the plastic ring gear that the shaft mates with. Cuisinart discontinued this item, so sadly, those of us that feel fixing is better than trashing… too bad. What to do with a motor that’s just fine, and nothing to drive with it? TRASH. Just what the planet needs… :(

That's not a fix, that's a replacement.
Anyone know how to take apart the blade/shaft assembly?

Seems a bit like overkill. If it’s gone far enough to need help, there is probably enough clearance between the bearing surfaces/seal to gradually oozle in a bit of food-grade caster oil (applying small amounts and hand rotating/pushing pulling the blade repeatedly) to get the bearing surfaces slippery. Even the tiny bit of play I felt in mine resolved with this exercise. It remains to be seen how long this will last, but clearly the fallback position is replacement.

I had the same problem with a full size Cuisinart blender. Instead of castor oil I used a very small amount of pharmacy grade mineral oil on top and bottom of the bearing and it helped loosen the cutting blades somewhat.
Bad design from a famous company.

I know this is a very old thread, but better late than never. I was able to fully "undo" the almost frozen lower bearing by turning it upside down, putting food grade silicon SPRAY oil in the cup above the bearing. I let it set for a hour then put the motor on slow speed and ran it upside down with the oil in the cup. It is fully free and loose, but not damaged. I will continue to lubricate this with the spray. Best of success to you all!

What are the odds that I'd find a 6 year old post and your contribution from less than an hour ago. Trying this right now with Zep food grade silicone spray.
I heard it improve once I ran it with it upside down. The whisk head is a different story. Still has a loud and obnoxious whine. But thanks for your post.
