Precision Rotation with Serpent SER1398

Model racers and hobbyists who value straightforward parts swaps will appreciate the Serpent SER1398 bearings. These flanged stainless steel units, sized 4x8x3mm, are designed to lower friction and extend service intervals on common RC components.

Where These Flanged Bearings Shine

The 4x8x3 flanged bearings are useful in hubs, steering assemblies and small drivetrains. They help maintain consistent roll and reduce the frequency of bearing changes across a variety of surfaces.

Care and Mounting Recommendations

Make sure each bearing is driven square into its seat and spins freely after fitting. Keep them clear of abrasive debris and reapply a light lubricant during maintenance checks. They suit both road circuits and mild off-road use.

Can I mix these bearings with sealed types in the same model?

Mixing open flanged bearings with sealed ones is fine where space and fit allow, but expect minor differences in drag and maintenance needs between types.

How do I tell when a 4x8x3 bearing needs replacing?

Listen for grinding or feel for roughness when rotating by hand; increased play or visible pitting are signs to replace the bearing promptly.

Is extra lubrication needed after initial install?

A light oil after installation helps ensure smooth break-in. Avoid over-greasing small bearings as that can raise resistance and attract dirt.
