8x19x6mm Precision Ball Bearings ABEC 3 Rubber Sealed BU (10)

I bought these because the bearings in my Ninja Foodi blender were bad and there was a video saying the replacements are 8x19x6. Well, it turns out Ninja managed to find some custom proprietary bearings that are actually 7.8x19x6 (which I can't find anywhere!). So these bearings will not fit firmly on the blade shaft, because of that .2mm difference in diameter. They'll technically "work", but they'll basically just be spacers. The bearings wont actually be spinning. Definitely not the fault of the bearing manufacturer or this seller though!Btw, to fix my Foodi bearings I just pulled them out, removed the rubber seals, and cleaned the bearings with acetone until they spun smoothly. Then I used roller skate bearing lube (speed cream from Rollerbones) and put it all back together. Problem solved!

We have a nutribullet blender, with that single cup attachment. Use the heck out of it.When you wash the blender base, especially the base side, it becomes saturated with water. Well, nutribullet engineers must have thought "no customer will ever submerge a blender base to clean it!". Bunch of dummy's.They dont put in stainless bearings and it WILL RUST OUT. Then one day you make your macho mango smoothie and the thing is whirring like crazy and smoke is bellowing out the base!!!These are the replacement bearings. You need 2 of them, stacked. Google or YouTube how to do it. It's a real PITA but worth it if you want to save a few bucks and use your blender for longer than 6 months.

Used to replace bearings in my Nutribullit, made the bleander very quiet.

Happy with the bearings...Good quality as they had to be at ABEC rated. They are working well

Did not last beyond first use. We used these bearings as a replacement in our smoothie blender. During 2nd use, the brown lubricant was oozing out into the drink container. Tried again using another set of beatings, and same thing happened. Very disappointed that we did not get our money’s worth.
