2026 brand-new Hitachi EX200 and EX300 track rollers are forged from high-strength heat-treated alloy steel for medium and large excavators. Boasting heavy load-bearing capacity and excellent wear resistance, they adapt to long-term heavy construction work. The fully sealed lubrication structure effectively isolates mud and water to prevent oil leakage and premature damage. OEM standard size guarantees accurate fitting. Factory direct sales offer cost-effective prices and generous bulk discounts.
