Choosing between undercarriage parts starts with the component named in the repair: a bottom roller and an idler pulley are different choices. For heavy equipment engines undercarriage parts, match the part type and named excavator first, then use construction and listed price to narrow the decision. These two options have a $133.17 listed-price spread, but their titles point to different undercarriage roles.
Quick verdict
Choose the Bottom Roller Track Roller Fit FOR IHI IHI32J Mini Excavator Undercarriage Parts when the job specifically calls for a bottom or track roller for the named IHI mini excavator. Choose the Carbon Steel Idler Pulley for John Deere 17G Mini Excavator Undercarriage Parts when the required component is an idler pulley for the John Deere 17G application named in its title. Both are described as new direct-replacement parts and include a stated two-year manufacturer warranty, so the decision comes down to component role and equipment match.
At-a-glance comparison

|---|---|---|
| Listed price | $45.99 | $179.16 |
| Component named | Bottom roller / track roller | Idler pulley |

Where each part fits best
The IHI entry is the clearer match for an IHI IHI32J bottom-roller request. At $45.99, it is the lower-listed-price choice and is explicitly labeled as a bottom roller/track roller.
The John Deere entry fits the other branch of the decision: a repair calling for an idler pulley for a John Deere 17G. At $179.16, it is the higher-listed-price option and names carbon steel as its material. The titles identify different undercarriage component types, so treat this as a part-matching choice rather than two versions of the same component.
Product notes
Bottom Roller Track Roller Fit FOR IHI IHI32J Mini Excavator Undercarriage Parts
The Bottom Roller Track Roller Fit FOR IHI IHI32J Mini Excavator Undercarriage Parts is a focused choice when the repair calls for that roller style on the named IHI mini excavator. A steel build, black finish, and Direct Replacement fitment language give it a clear component-specific profile. Its description also calls out high-strength hardened steel, seal groups intended to retain lubricating oil, and sealed bearings intended to help keep dirt, mud, and grime from inner components. The key limitation is equally specific: the stated application is IHI IHI32J, making it most appropriate when that exact equipment name and bottom-roller requirement align with the job.
Carbon Steel Idler Pulley for John Deere 17G Mini Excavator Undercarriage Parts
Carbon Steel Idler Pulley for John Deere 17G Mini Excavator Undercarriage Parts suits work that calls for an idler pulley rather than a track roller. The description identifies carbon steel and a package containing one idler pulley, while its Direct Replacement wording positions it as a replacement component. The title names the John Deere 17G, and its compatibility language also references selected Hitachi and John Deere mini excavators. One practical limitation is explicit: installation instructions are not included, while professional installation is highly recommended. Choose this option when the named part role is an idler pulley and the John Deere 17G application is relevant.
