Precision Bearings for Smooth Runs

Arrowmax AM-200123 4x8x3mm ball bearings are made for RC hobby use, lowering friction in rotating parts to help your model run more smoothly. Built from metal with close tolerances, they support steady drivetrain performance during regular use.

Performance Benefits for RC Drives

Good bearings cut down drag and reduce wear on gears and shafts. The Arrowmax AM-200123 pair can serve as direct replacements or upgrades, delivering reliable rotation and longer service life when maintained correctly.

Fits and Typical Uses

These 4x8x3 bearings suit many small hubs, idlers and gearbox shafts found in car, truck and crawler kits. They install easily and are a practical choice when refreshing worn running gear.

Will these bearings match my model's spec?

Measure the bearing bore and shaft in your manual or on the part; these are standard 4x8x3mm bearings so they fit any application that calls for that size.

How should I lubricate them?

Use a light bearing oil or a thin grease sparingly. Clean old grease and debris before reapplying to keep rotation free and to avoid trapping grit.

Can these handle hobby racing speeds?

These metal 4x8x3 bearings are suitable for typical hobby speeds; for extreme high RPM builds check seals and lubrication and consider specialist racing bearings if needed.
