This is a pack of ten 5x11x4mm rubber sealed "Speed" clutch bearings. ProTek R/C "Speed" bearings are high quality steel/chrome bearings designed for the R/C racing enthusiast.

These 5x11x4mm rubber sealed bearings are the standard bearing for many monster truck clutches, such as the Traxxas T-Maxx and Traxxas Revo. Some racers prefer the rubber sealed bearings for better protection against dirt for their clutch. Please check the manual that came with your vehicle for the correct size if you are not certain.

These are also used as wheel bearings in the Kyosho Lazer ZX-5 1/10th scale 4WD electric buggy.

I tend to trash bearings fairly quickly on my Rustler VXL. Too many cock-eyed landings. I've been through a fair amount of these bearings and have been extremely pleased with them. The price is great and my wheels spin just as long and just as easy as they do with the more expensive Traxxas bearings. Personally, I prefer these because it's not expensive for me to swap out bearings whenever they get too beat up to spin perfectly smoothly. Between the crashes and the dust, they take quite a beating. I don't know what others do, but I've had the best from these if I put a drop or two of thin motor oil (like what I run in my pickup) on each side of the bearings, let them sit for a minute to soak up the oil, then wipe them off before installing them.

pretty good so far but i think there durability might not be as good as the Traxxas ones.

I don't like these bearings, yes they are inexpensive, but they last like it too. Taking the clutch apart multiple times during a race is not my idea of a bargain. Buy the good/expensive bearings and you'll be a much happier racer!
