Engineered for Consistent Rotation

The Arrowmax AM-200123 4x8x3 bearings are compact metal components designed to deliver stable rotation in small RC assemblies. Their 4x8x3mm sizing matches many hobby applications where dependable bearings are needed.

Benefits for Racers and Hobbyists

Fitting quality bearings reduces wasted energy from friction and helps keep gear meshes aligned. Arrowmax AM-200123 bearings are suitable for both maintenance swaps and modest performance upgrades.

Installation and Fit Notes

These bearings are compatible with any mounting that accepts 4x8x3mm parts. Light tapping into place or a low-force press will seat them correctly; avoid stressing the races during installation.

What signs indicate replacement time?

If you notice grinding, excess play or rough rotation, it is time to replace the bearing. Regular inspections catch wear early and protect adjacent parts.

Are they suitable for wet conditions?

Standard metal bearings can tolerate occasional moisture but are best kept dry and re-lubricated after exposure. For frequent wet use consider sealed or stainless options.

Can I upgrade to ceramic bearings?

Ceramic bearings offer lower friction and lighter weight but at higher cost. Match dimensions to AM-200123 when selecting an upgrade to ensure correct fit.

How often should I service them?

Service intervals depend on use; inspect and clean after every few runs if you race regularly, or during routine maintenance for casual use.

Where to source replacements?

These are a common 4x8x3 size stocked by many hobby shops and online retailers; keep the Arrowmax AM-200123 part number handy to find exact matches.
