ProTek RC 5x11x4mm Metal Shielded "Speed" Bearing (10)
I used these for wheel bearings in my castle powered stampede 4x4 and I didn't even get through one battery before the balls shattered and one of.my wheels flopped around. Used the entire 10 pack to try and keep my truck running. The track I run at has been damp when the bearings blew up. 3 stars cause it may be my mistake, are "clutch bearings" a different type of bearing? Pulled the bearings out of my axial crawler and I've ran 5 packs no problems.

Like what was previously mentioned these bearings work great and last a long time. No need to spend a lot of money on bearings when you can get these at a very good price. I also use the speed wheel bearings in all of my nitro and electric vehicles.

Ran these Bearings on D812 Clutch Bell, 28 tanks of fuel, Pulled motor look at them, Shields still on and spin freely looks like they could go another 20 tanks, But this a good time to oil them. Good bearing Good price.
