Overview:
This bottom track roller is a non-genuine replacement designed for Kubota mini excavators, giving smooth track rotation and dependable support for the undercarriage. Built with a robust steel body and a hard-wearing finish, it carries machine weight, guides the track, and helps minimise vibration and wear on the chain and track links. It is a direct-fit alternative for Kubota K008-3 and U10-3 machines and replaces OEM reference RA021-21702. The roller is intended to install on the lower undercarriage using the machine's existing mounting points and hardware.
