Product Overview

This high-quality Original Crankcase Bearing Radial Ball 6004U is designed to meet or exceed factory performance standards and is suitable for Honda PCX125 (2018-2020) models.

The crankcase bearing radial ball 6004U is a precision bearing that provides smooth, low-friction support for the rotating shafts within the engine crankcase, enabling the engine's internal components to operate efficiently and quietly throughout the full range of engine speeds. As the bearing wears through normal use, the rolling elements develop surface pitting or spalling, the cage degrades, and internal clearances increase, resulting in audible bearing noise, increased vibration, and the risk of sudden bearing failure that can cause significant engine damage. This original replacement restores the original crankcase bearing precision and performance, ensuring seamless, secure, and reliable operation of your PCX 125.

Complete Part Guide

The 6004U radial ball bearing is a vital rotational anchor for the 2018-2020 Honda PCX125, supporting the internal shafts within the crankcase and gearbox interface. A failing bearing typically manifests as a high-pitched "whirring" or a deep metallic drone that intensifies as engine RPM increases. This original Honda part (91016-KBB-901) features a specialized single-lip seal to maintain lubrication while protecting the races from engine debris.

We frequently find that high-mileage Honda PCX-125s develop a "growl" from the transmission, often traced back to a worn 6004U bearing. Once the internal races become pitted, the resulting vibration can cause premature wear on the oil seals and shafts. Replacing a noisy bearing promptly is essential to prevent a catastrophic gearbox failure. This original Honda Crankcase Bearing Radial Ball 6004U (91016-KBB-901, 2018-2020) is manufactured to factory tolerances, ensuring a press-fit that eliminates shaft play and restores the smooth, silent operation required for city commuting.
