When your IHI mini excavator's undercarriage shows wear, the replacement part you need depends on your exact model and which component has failed. This comparison puts a bottom roller for the IHI32J next to a sprocket for the IHI30G, so you can weigh their listed prices and features side by side. Both are new parts, but they are not interchangeable, so the right choice comes down to your machine and the job.
Quick verdict
If you have an IHI32J and need a track roller, the Bottom Roller Track Roller is listed as a direct replacement with a black finish and a two-year manufacturer warranty. If you have an IHI30G and need a sprocket, the New Fit For IHI IHI30G Sprocket is the component for that task. Each part fits a different model, so confirm your machine and component before ordering.

Product notes
Bottom Roller Track Roller for IHI IHI32J
This new bottom roller is a direct-replacement part with a black finish. It is built with hardened steel and sealed bearings that keep dirt, mud, and grime from penetrating internal components, according to the manufacturer. It also includes a two-year manufacturer warranty. The limitation is that it only serves as a roller, not a sprocket, and it is designed specifically for the IHI32J. If your machine is an IHI30G or the worn component is a sprocket, this part will not solve your problem.
New Fit For IHI IHI30G Sprocket
This new sprocket comes from a manufacturer that says it has over 20 years of experience producing undercarriage parts for mini and large excavators and bulldozers, with clients that include Volvo, Caterpillar, Hitachi, Mitsubishi, and Komatsu. The part type is categorized as bearings, and it is specified for the 2017 model year. The limitation is that it will not fit the IHI32J and it cannot replace a bottom roller. Be sure your machine is the IHI30G and the failed component is the sprocket.
Final choice by use case
- For an IHI32J bottom roller replacement: choose the Bottom Roller Track Roller at USD 45.99.
- For an IHI30G sprocket replacement: choose the New Fit For IHI IHI30G Sprocket at USD 194.00.
- If you're unsure whether your machine is the IHI32J or IHI30G, or whether the failed component is a roller or a sprocket, identify those two details first, because these parts are not interchangeable.
