Smooth Rolling with RADTEC BB-20003

Upgrade your RC car with RADTEC BB-20003 ceramic ball bearings for noticeably smoother rotation and improved drivetrain efficiency. These 5x8x2.5mm bearings use ceramic balls to lower friction and resist wear, making them a solid choice for routine servicing or performance improvements across many models.

Red Rubber Seal for Everyday Protection

The red rubber seal on each bearing keeps dirt and grit out while holding lubricant in place. That seal helps reduce maintenance frequency and keeps rolling resistance consistent during both track days and backyard bashing.

Ceramic Advantages for RC Use

Ceramic bearings run cooler and with less drag than standard steel units, which can translate to crisper throttle response and steadier top speed. They are a favoured upgrade for drivers looking to refine handling and reduce drivetrain losses.

What sizes and models accept these bearings?

These 5x8x2.5mm bearings fit many 1/10 scale wheel hubs, axles and gearbox shafts. Check the bearing ID and width in your model manual before buying to confirm fitment.

Are the bearings pre-lubricated or do they need servicing?

The sealed design retains lubricant from the factory, but periodic inspection and light relube after heavy use will extend service life. Avoid solvent cleaning that can strip grease from the seals.

How should I install them without damaging the seal?

Press bearings straight into place using a proper driver or socket that contacts the outer race only. Do not hammer the inner race and avoid sideways force that could deform the seal.
