Product Details

This is the aftermarket replacement bottom roller for Kubota KX 161-3, Kubota U-45-3, and Kubota U 40-3 rubber track mini excavators. 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 complete assembly and you can reuse your factory bolts for easy installation. This roller is also designed to fit the newer Kubota KX 057-4 and U55-4 mini excavator as well. This is not guaranteed for the Super Series steel track models. You must verify measurements if you have a SS. Our Kubota undercarriage parts are backed by the factory for one year pro-rated warranty against manufacturing defects.
