This is the aftermarket replacement bottom roller for Kubota KX 161-3, Kubota U-45-3, and Kubota U 40-3 mini excavators. This bottom 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.
