Bobcat 7004843 Carrier Roller Assembly

The 7004843 carrier roller is a critical undercarriage component designed to support the upper track chain on mini excavators. Manufactured from high-strength alloy steel with precision-machined surfaces, it features a sealed floating duo-cone seal assembly to prevent contaminant ingress and retain lubricant, ensuring extended service life in abrasive environments. This upper roller assembly replaces Bobcat OEM part numbers 6692966, 6809980, 7020867, and 7132416, and cross-references Doosan OEM 2270-1134. It is engineered to meet OEM dimensional and metallurgical standards for direct bolt-on installation without modification. The roller shell undergoes induction hardening to optimize wear resistance against track link contact. Application coverage includes Bobcat E60, E62, E63 mini excavators and Doosan DX55, DX60R, DX62-R-3, DX63-3 mini excavators. Verification of machine serial number is recommended prior to installation due to potential mid-year production changes.
