Arrowmax 5x10x4mm AM-200105 Ball Bearing Pair  [AM-200105]

Performance Bearings Built to Last

Small components make a big difference in drivetrain feel. The Arrowmax AM-200105 Ball Bearing set (5x10x4mm) reduces rolling resistance so power transfers more efficiently through the drivetrain.

Sealed for Tough Conditions

The rubber seals help prevent grit and dust from entering the bearing, which preserves smooth rotation under load. That protection suits these bearings for mixed-surface running where contaminants are present.

Quick Upgrade, Noticeable Result

Because 5x10x4mm is a common size, these bearings replace worn units quickly and provide an immediate improvement in smoothness and noise reduction.
