Kubota KX 161-3 U-45-3 Lower Roller

This is the aftermarket replacement bottom roller for Kubota KX 161-3, Kubota U-45-3, and Kubota U 40-3 mini excavators. This roller is also designed to fit the newer Kubota KX 057-4 and U55-4 mini excavator as well. This bottom roller utilizes an all-new sealed ball-bearing design. The bottom roller comes with a stainless steel shaft for years of durable service and reliability. It is highly suggested to replace all the rollers on one side as opposed to just replacing one roller at a time. One new roller installed next to worn rollers will put uneven weight distribution on the new roller limiting the lifespan of the new roller. These rollers come as a complete assembly and you can reuse your factory bolts for easy installation.

This is not guaranteed for the Super Series models. You must verify measurements if you have a SS.

We now stock the steel track version of these rollers so please indicate if you are running steel tracks on your mini excavator.

Our Kubota undercarriage parts are backed by the factory with a standard warranty against manufacturer defects.
