Excavator undercarriage parts are easy to ignore until a track starts riding unevenly or making noise. For Case CX36B owners, the bottom track roller is one of the components that takes constant wear. This guide focuses on a new heavy-duty replacement roller and helps you decide whether it's the right part for your undercarriage service.
Quick Verdict
The New Heavy Duty Bottom Track Roller For Case CX36B Excavator Undercarriage Parts is a single replacement roller priced at $129. If you're servicing a CX36B undercarriage and need one bottom roller, this part is a practical candidate.
Who It Suits
This roller is intended for a Case CX36B excavator, per the compatibility details. It's a new component rather than a used or remanufactured part, which can give you confidence when you're rebuilding the undercarriage. It suits anyone who wants a replacement bottom track roller with a specific steel alloy and hardness range, rather than an unspecified generic part.
What Stands Out
The highlighted details are the material and hardness. 50 MnB steel is a type of boron steel often used in heavy-duty wear parts because it can handle impact and abrasion. The surface hardness of HRC52-58 is a solid range for track roller contact. The hardened depth of 5mm to 10mm shows intentional hardening beyond just a thin surface layer. The roller is black, and the package dimensions are 5.51" x 5.51" x 8.26".
Meaningful Trade-Offs
This is a single roller, not a set. Replacing multiple rollers on the same undercarriage will add up, so consider the total number you need. The compatibility with the Case CX36B is clearly stated, and the material specs are solid, but the part is sold individually rather than in a multi-pack.
