When you're shopping for undercarriage parts for mini excavators, the part number matters as much as the machine itself. A bottom track roller built for a Case CX36B won't help an IHI IHI30G, and a sprocket for an IHI IHI30G won't bolt onto a Case. The two parts here are both new, but they're not interchangeable. One is a heavy-duty bottom track roller for a Case CX36B; the other is a sprocket for an IHI IHI30G. The real question isn't which is better overall-it's which one matches the machine you're working on.
Both parts are new, but they occupy different roles. The bottom track roller supports the track along the ground, while the sprocket drives the track from the end. Because they serve different functions, the choice comes down to which part your machine needs.
Quick Verdict
If you have a Case CX36B and need a replacement track roller, the New Heavy Duty Bottom Track Roller For Case CX36B Excavator Undercarriage Parts at USD 129.00 is the part to choose. If you have an IHI IHI30G mini excavator and need a new sprocket, the New Fit For IHI IHI30G Mini Excavator Sprocket Undercarriage Parts at USD 194.00 is the one to consider. Both are new parts, but they serve different machines and different positions on the undercarriage.

Product Notes
New Heavy Duty Bottom Track Roller For Case CX36B Excavator Undercarriage Parts
Choose this new bottom track roller when your excavator is a Case CX36B. It's marketed as heavy-duty. The material is 50 MnB steel, and the item weight is 13.23 pounds, with package dimensions of 5.51" x 5.51" x 8.26". The surface hardness range-HRC52-58 with a depth of 5mm-10mm-is included in the product description. This part is specific to Case CX36B excavators and it's a roller, not a sprocket. If you own a different model or need a sprocket instead, this part won't match. The roller is designed for the bottom of the track assembly, so it isn't a substitute for a sprocket. This roller is made for the CX36B undercarriage and is not a universal part.
New Fit For IHI IHI30G Mini Excavator Sprocket Undercarriage Parts
Choose this sprocket when your machine is an IHI IHI30G mini excavator. It's a new part with a model year of 2017 and part number FLTIHI30GSK. The product also carries a GTIN of 656664697768. This is a sprocket, not a track roller, so it addresses the drive end of the undercarriage rather than the bottom roller area. If you need a roller or your excavator is a Case CX36B, this sprocket won't be the right fit. The sprocket is meant for the drive end, so it won't serve as a roller. This part is aimed at the IHI IHI30G and should be paired with that machine.
Final Choice by Use Case
If you own a Case CX36B and need a bottom track roller, the New Heavy Duty Bottom Track Roller is the part you want. If you own an IHI IHI30G and need a sprocket, the New Fit For IHI IHI30G Mini Excavator Sprocket is the part you want. For any other excavator model, neither of these parts is the correct fit. Double-check your equipment model and the part type before making a decision.
