RADTEC RAD-BB-20004 Ceramic Bearing Solution

For precise rolling performance, the RADTEC 4x8x3mm flanged ceramic ball bearings offer lower friction and enhanced wear resistance. They are a compact replacement for applications that demand steadier rotation.

Core Benefits

Ceramic Ball Bearings: Deliver reduced friction and improved thermal stability under load.
Flanged Shape: Facilitates correct placement and prevents axial movement in many housings.
Red Rubber Seal: Guards against dust ingress and helps maintain internal lubrication.

Suitable Applications

Well suited to competition and hobby RC cars, as well as other small mechanisms that use 4x8x3mm bearings. Fit them where you need improved wheel response or cleaner drivetrain operation.

Will these bearings suit vintage RC kits?

Many vintage kits that accept 4x8x3mm bearings can benefit, but check that the flange does not obstruct surrounding parts. Measure the housing depth and entry diameter first.

How often should I relube them?

Frequency depends on usage conditions; for regular dry running, inspect and re-lube every few months. After dusty or wet sessions, clean and reapply lubricant promptly.

Are these compatible with electric motor bearings?

They can be used where the motor shaft and housing accept 4x8x3mm flanged bearings, but ensure the flange does not interfere with rotor clearance and that the bearing suits motor rpm and load.
