Title:
BUSH (KU-RB23766570)
Description:
The Genuine Kubota BUSH (Part No. RB237-66570 / KU-RB23766570) is an OEM pivot bushing designed for compatible Kubota mini excavators. This precision-machined bush acts as a wear-resistant bearing surface between pins and mounting points, helping maintain correct clearances, reduce friction, and support smooth movement of machine components.
Manufactured to Kubota’s original equipment specifications, this genuine replacement bush provides the correct dimensions, material quality, and fit required for reliable operation. It is designed for use in pivot and linkage assemblies where components experience repeated movement, vibration, and heavy working loads.
Bushes are critical wear components in excavator linkage systems. Over time, normal operation can cause wear between pins and bushings, leading to increased play, reduced control accuracy, vibration, and accelerated wear of surrounding components. Replacing worn bushes with genuine Kubota parts helps restore proper alignment and smooth machine operation.
