What Is a Carrier Roller for Hitachi ZX200/EX200 Excavators ?
The carrier roller, also known as the upper roller, plays a critical role in stabilizing the top of the track chain on tracked excavators. Unlike track rollers that support the machine's weight from below, carrier rollers guide the track from the top, preventing slack and minimizing uneven wear.
Whether you're operating a Hitachi ZX200 or an older EX200 series, a high-quality carrier roller ensures smooth movement, improved undercarriage longevity, and better fuel efficiency due to reduced resistance in track travel.
Compatible with Multiple Hitachi Models
Our carrier roller offers excellent compatibility across various Hitachi models. It is not limited to the ZX200 — it's also fully compatible with the following:
EX200-1 / EX200-2 / EX200-3 / EX200-5
ZX200 / ZX200-3 / ZX200-5G / ZX210
This cross-model compatibility reduces your inventory management burden and ensures easy replacement for multiple machines in the fleet.
Premium Materials and Wear-Resistant Construction
We use top-tier materials and precision processing to manufacture each ZX200/EX200 series upper roller:
Raw steel processing → Forging → CNC turning
Induction hardening → Bushing & seal assembly
Final inspection → Surface treatment → Packaging
Each step is executed by experienced technicians under ISO-standard supervision. Our in-house testing includes concentricity, hardness, seal integrity, and runout accuracy, ensuring your roller fits perfectly and lasts longer.

Key Material Highlights
- Roller Shell: Forged from high-strength alloy steel (50Mn or 40Mn2), ensuring structural integrity under heavy loads.
- Shaft: Induction-hardened 45# or 40Cr steel shaft with HRC52–58 surface hardness.
- Seals & Bushings: Fitted with high-performance floating seals and wear-resistant bushings for excellent sealing and longevity.
This material combination guarantees resistance to deformation, cracking, and abrasive wear even in rocky, muddy, or high-vibration environments.
