Default Bearing choice

What is a good bearing for the diffs, and the wheels.

I need to replace some bearings in the wheels. I had the PTFE sealed bearings in my tc3. Two went bad. Should I buy the same kind or should I go with a rubber sealed bearing for the wheels and PTFE sealed for the diffs.

Please help this bearing noob.

if you race stock you would want minimum resistance. so go with steel sheild. but be prepared to clean the bearings every second race meet if you race foams, maybe every 3 or 4 race meets if you race rubbers.

if the diff bearings are relatively hidden away from dirt and stuff, go with metal sheilds for the diffs and rubber at the hubs, were maybe it is more exposed to dirt.

the rear bearings will get more dirty than the fronts. you could consider a weird setup of metal sheilds up front and rubber sheilds at the rear.

but after all of that i'd probably just say go metal sheilds.

yes metal sheilded are a good choice but you may want to check out acer bearings. they are a bit expensive but they last a lot longer then regular bearings

For many years in my sedans I started running with no shields. It is easier to clean, things don't get trapped inside the shields to ruin them and I feel much happier about it. Usually it is good to clean them before every other race day. I shake them in motor spray, used canned air to blow them out and then oil them up.

I got tired of dealing with sealed bearings and carpet or dirt fibers getting caught in them. I cannot think of the last time I lost a bearing like this. I cannot even count on one hand the number lost. With shields I can count on both hands.

Good point A-Ko with a shield there is a greater chance of something get inside and destorying the bearing. the only badthing about no shields is they have to be cleaned. also with no shields there is less resistence. for the bearings in hub carries i would run one shield on the outside and none on the inside of the carrier, this is a medium of both worlds.

This is how I've been running mine, and I am very pleased with how they are performing.
