RADTEC RAD-BB-20004 Ceramic Bearings for RC Upgrades

These RADTEC 4x8x3mm flanged ceramic ball bearings are a straightforward swap to reduce drag and boost rotational consistency. They are a compact upgrade for racers and weekend bashers alike.

Notable Advantages

Ceramic Ball Bearings: Offer smoother spin and improved resistance to wear in frequent use.
Flanged Construction: Easier alignment and a snug seating in many common hubs and carriers.
Red Rubber Seal: Adds a barrier against grit and helps maintain internal cleanliness.

Recommended Uses

Use these bearings in wheel hubs, idler shafts, and other 4x8x3mm locations where lower friction and better durability are needed. They are suitable for on- and off-road RC layouts.

How do I check fitment for RAD-BB-20004?

Measure your existing bearing seat and shaft to confirm the 4x8x3mm dimension and check for flange clearance so the bearing sits flush without rubbing.

Can I run these in wet conditions?

The red rubber seals help block splash and fine moisture, but prolonged exposure to water may still allow ingress. Rinse and dry after wet runs and re-lube where needed.

Are they worth fitting to older models?

Yes, replacing worn steel bearings with ceramic versions can noticeably reduce drag and restore smoother steering and wheel spin on older cars.

Do the red seals affect friction?

Seals add a small amount of drag compared to open bearings, but the ceramic balls counteract this with lower rolling resistance overall, giving a net improvement in many setups.
