Description
Overview:
The Makita 6900ZZ Ball Bearing is a genuine Makita replacement part for selected circular saws, including the BSS500 and BSS501. It is a deep groove ball bearing made from hardened bearing steel with twin metal shields (ZZ) to help keep out dust and debris while retaining lubricant. Used in high‐speed rotating assemblies such as the blade spindle or motor, it supports smooth, accurate rotation and reduces friction and wear. The 6900 series bearing typically measures 10 mm internal diameter x 22 mm external diameter x 6 mm width, providing a compact, low‐profile fit suitable for saws where space and balance matter. Supplied under OEM number 210080-0, this genuine part restores consistent performance and extends tool life when a worn or noisy bearing needs replacement.
