Compact Ceramic Bearings for Hobby Performance

For modelers looking to refine handling and efficiency, RADTEC supplies 4x8x3mm ceramic ball bearings fitted with a red rubber seal. They are built to smooth rotations and prolong the life of driveline parts.

Low Friction Construction

Ceramic balls provide lower rolling resistance and strong wear characteristics, helping shafts and gears spin with less drag. This makes them suitable for both casual running and competitive use.

Seal That Keeps Out Debris

The red rubber seal protects the bearing interior from dust and splatter, keeping lubricant where it belongs and reducing the need for frequent servicing after dusty sessions.

Suitable for Many RC Types

The standard 4x8x3mm dimensions let these RADTEC bearings work across a broad selection of RC cars, trucks and buggies, offering a straightforward replacement or upgrade option.

How do I check bearing fitment?

Measure the bore and outer housing of your component and confirm they match 4x8x3mm bearings, or consult your model manual.

Should I relube sealed bearings?

Sealed bearings come pre-lubricated, but if you notice drag after heavy use you can remove seals carefully to clean and relube when needed.

Can I use them on both front and rear axles?

Yes, these bearings are versatile and can be used wherever 4x8x3mm bearings are specified, subject to fit checks.

Do they need breaking in?

New ceramic bearings often run smoothly from the start, though a short bedding-in period under light load can help seating.

What maintenance prevents failure?

Keep seals intact, avoid abrasive contamination, and inspect periodically. Replace bearings that show pitting or excessive play.
