E325 Lower Roller 117-5046, Track Roller Made Of 35MnB Alloy Steel For E325 Chassis Load-bearing Spare Components
Product Overview
This 117-5046 E325 lower track roller is a heavy-duty load-bearing undercarriage spare part customized for E325 series excavator chassis support and heavy-site construction work. Different from ordinary track rollers adopting common carbon steel raw materials, this bottom roller adopts full 35MnB high-strength alloy steel for overall production. This upgraded raw material delivers stronger pressure resistance, better abrasion resistance and excellent fatigue resistance, perfectly matching the heavy load demand of large-size excavator chassis. As a professional undercarriage parts factory, we strictly inspect raw material composition before production to ensure stable load-bearing performance for long-term heavy-duty construction.

Differentiated Material Quality Control
Most regular aftermarket track rollers use low-cost ordinary carbon steel, which cannot withstand long-term heavy chassis pressure, leading to rapid surface wear, shaft stuck and roller collapse under heavy working conditions. Our 117-5046 lower roller takes 35MnB alloy steel as exclusive raw material, with fixed chemical component ratio and higher mechanical strength. Every batch of steel materials will pass strict component inspection before production. We match targeted heat treatment process based on material features, ensuring the roller keeps stable load-bearing capacity without deformation or wear failure under long-time heavy pressure.
Core Product Advantages
-
Premium 35MnB Alloy Steel Material: Higher compression resistance and wear resistance than common carbon steel rollers, suitable for long-duration heavy-load chassis bearing work.
-
Stable Heavy-load Performance: Optimized material toughness avoids roller deformation, shaft damage and track collapse caused by overweight construction pressure.
-
Uniform Heat Treatment Effect: Consistent overall hardness reduces unilateral wear, keeps track running smoothly and cuts down later maintenance cost.
-
Accurate Original Size Matching: Fully compliant with 117-5046 standard installation dimensions, supporting direct replacement without on-site cutting or modification.
Packaging & Factory Service
This 35MnB alloy steel lower roller is specially designed for E325 series excavator chassis load-bearing replacement and heavy-duty site undercarriage maintenance. Each roller is coated with anti-rust oil independently, wrapped with waterproof protective film and packed with sturdy wooden boxes to prevent extrusion damage during ocean transportation. We support material inspection reports, sample orders and bulk wholesale, providing durable heavy-load chassis spare parts for global construction equipment wholesalers and repair workshops.
