ProTek RC 8x16x5mm Metal Shielded "Speed" Bearing (10)

Great price, good Protek 8x16 metal shielded bearings and they last for a long time. These last as long as any other bearings on the market as I have tried all the bigger name brands and even the overpriced ceramic bearings, as I race a lot. These work great in both my MBX6R 1/8 scale nitro and MBX6 Eco, but do realize I do check and possibly change out bearings about every race, but at this price, that is cheap maintenance to replace. I personally prefer the metal shielded bearings over the rubber shielded as they provide less restriction, but just remember to check them regularly as they do not seal as well as the ProTek rubber shielded bearings.

I bought these to put in my brand new build. I put them on my wheels and diffs of my Kyosho 1/8 buggy. Changed the front diff fluid after two races and both bearings had some slight crunch but thankfully they did not fail on me. It was clean inside the diff area. Slightly disappointed but for the price i suppose it’s not bad. Maybe I expected more run time since it was on the diff. I would purchase again, but I’d check them frequently.

Reliable and consistent bearings. They distinct from the way they are sealed. I like the chrome metal shield they are covered. Bearings came well greased and lubricated. Great price vs quantity too! I have it on my MP777 SP2 for two endurance races but still they ran as equal as the first time being installed on my vehicle.

Purchased these as I needed 4 inner bearings to run the universals on my ET48.3. After 2 packs, about 30 minutes on the dirty track I took the truck apart and found that the rear 2 were pretty crunchy already. The stock outer Tekno bearings were still smooth as new. I cleaned and oiled them and put them back in so we will see how they are after another few packs. I was expecting them to keep more dirt out, but I have extras and they are cheap so its no big deal..

UPDATE: I've had the Truggy for 1 month now, and take it to the local track 2 or 3 days a week. I typically run 3 or 4 batteries though it, as well as the Tekno SCT410.3 I bought a couple weeks ago. I do a complete tear down about every 10 days, so on average about 2 hours of run time. All of the rubber sealed tekno bearings on both rigs have plenty of life left, with most of them feeling good as new so I just re-oil and put them back. The 4 Protek bearings on the inside of the hubs dont even spin anymore when i tore the truck down tonight. They just easily spin on the axle shafts because they have so much dirt in them. I will say that pretty much every time I've driven them it's been pretty dusty conditions, but they have never seen wet or muddy conditions. From now on I'll use up the 10 i got and order up the Tekno bearings instead. Or maybe i should have ordered the protek rubber sealed instead. Like I said before, they are cheap so it's no big deal, I just figured I would get more than a month out of them, and I really should have replaced them after 2 weeks...
