Description
Overview:
This genuine Kubota bush (part no. 68721-66522) is a precision-machined sleeve used at pivot points on Kubota mini excavators to control wear and keep pins running true. Manufactured from hardened steel for strength and longevity, it helps reduce friction, absorb impact loads, and protect the host bore from damage during everyday digging, grading, and lifting work. It is designed for an accurate press-fit and smooth operation in Kubota KX41-2 and U17 machines, maintaining tight linkage tolerances and dependable performance. Suitable for routine servicing or full pin-and-bush refreshes, this OEM component supports consistent movement of boom, dipper, bucket, and blade linkages, helping extend the service life of surrounding parts. Genuine Kubota quality ensures reliable compatibility and performance in demanding site conditions.
