Hitachi EX55 Excavator Bottom Roller – Premium Undercarriage Replacement
Product Overview
Maximize the ground contact and walking stability of your Hitachi EX55 excavator with our heavy-duty replacement Bottom Roller (Track Roller). As a critical component of the "four-wheel and one-track" system, the bottom roller supports the machine's weight and guides the track chain. A worn or leaking roller can cause track derailment and uneven wear. Manufactured to exacting OEM standards, this product offers a cost-effective and highly reliable alternative for EX55, ZAX60, and EX60 models.
Key Features & Benefits
-
Superior Material & Durability: Forged from high-quality 40Mn2 / 50Mn steel, our bottom rollers undergo a deep induction hardening process. This significantly enhances surface hardness (HRC 45-52) and core toughness, providing outstanding resistance to wear, impact, and deformation in harsh, rocky environments.
-
Precision Engineering: CNC-machined to strict tolerances, ensuring a seamless, drop-in fit for the Hitachi EX55. This precision prevents premature track wear, reduces vibration, and extends the overall lifespan of your undercarriage components.
-
Advanced Sealing System: Equipped with a multi-layer floating seal and high-performance O-rings, the bottom roller effectively retains internal lubrication while keeping out mud, water, and abrasive debris. This prevents internal bearing failure and ensures long-lasting, smooth rotation.
-
Wide Compatibility: Designed to be interchangeable with Hitachi ZAX60, EX60, and compatible with Sany SY55/60 series, making it a versatile choice for fleet maintenance.
