RADTEC RAD-BB-20004 Precision Ceramic Bearings

Upgrade pivots and wheel assemblies with the RADTEC 4x8x3mm flanged ceramic ball bearings for smoother rotation and extended component life. They suit builders who want consistent, low-friction parts without complex mods.

Performance Traits

Ceramic Ball Bearings: Improved longevity and lower rolling resistance compared to standard steel balls.
Flanged Profile: Helps locate the bearing quickly during installation and reduces lateral play.
Red Rubber Seal: Shields the internals from dust and light moisture for more reliable runs.

Where to Use Them

Ideal for tuning racing cars, drift rigs, and any small RC assemblies that use 4x8x3mm bearings. They are useful when you need smoother steering response or steadier wheel spin.

Do these bearings come pre-greased?

These bearings are lightly lubricated for storage and initial use. You can add a thin bearing oil for road use or re-lube with grease for off-road conditions.

Can I use them in gearbox shafts?

They are suitable where a 4x8x3mm bore and flange fit is required, including some gearbox and motor mount applications. Verify flange clearance before final installation.

What benefits do ceramic balls give over steel?

Ceramic balls reduce friction and resist heat better under high speed, which helps maintain smoother rotation and can reduce wear on mating parts.
