Key Features & Engineering Advantages

• Premium Material & Heat Treatment

  • Feature: Fabricated from high-strength, alloy steel with precise induction hardening on the sprocket tooth profiles.

  • Benefit: Creates an extremely hard, wear-resistant surface that withstands abrasion from the track chain, while maintaining a tough core to absorb impact shocks and prevent tooth breakage.

• Precision Machining for Perfect Engagement

  • Feature: CNC-machined to exact OEM dimensional tolerances, ensuring perfect alignment with the track chain and a seamless fit to the final drive hub.

  • Benefit: Eliminates improper track rolling and reduces noise, while preventing premature wear on both the sprocket and the track chain bushings.

• Robust Flange & Bolt Circle Design

  • Feature: The mounting flange is engineered for maximum structural integrity, with precisely drilled bolt holes and a true pilot diameter.

  • Benefit: Ensures a secure connection to the final drive, distributing stress evenly and preventing loosening or failure under high-torque conditions.

• Complete Assembly Solution

  • Feature: Supplied as a fully assembled unit, incorporating the sprocket, hub, and necessary internal components.

  • Benefit: Drastically simplifies the replacement process, reducing labor time and the risk of incorrect assembly, getting your machine back to work faster.
