E312 Track Roller Replacement | CAT 312 | OEM Cross: 4I7346, 861934, CR5108.

Our E312 track roller is designed to be a direct, drop-in replacement for your CAT E312 excavator, perfectly matching the specifications of the original equipment. Cross-referenced with OEM part numbers 4I7346, 861934, and CR5108, this component ensures hassle-free installation without modifications, reducing downtime and keeping your operations running smoothly.

Constructed from high-strength alloy steel, the roller surface undergoes a specialized heat treatment process to achieve a hardness of 58-62 HRC, providing exceptional resistance to abrasion, impact, and corrosion. Whether your excavator operates on construction sites, mining fields, or agricultural terrains, this track roller is engineered to withstand heavy loads and extreme conditions, extending service life by up to 30% compared to standard aftermarket alternatives.

Featuring a double-lipped rubber seal with a metal dust cover, our E312 track roller effectively prevents dust, dirt, and moisture from entering the internal bearings. Pre-filled with high-performance lithium-based grease, the component maintains smooth rotation and reduces friction, minimizing wear on critical parts and eliminating the need for frequent re-lubrication.
