    One track size, broad machine coverage. The 300x52.5x76 Heavy Duty rubber track (12-inch) fits verified applications including Airman AX20-3, Airman AX20UR, Airman AX25-2, Bobcat E25, Case CX20B, and Case CX20BMR plus 51 additional verified machine. This 76-link configuration serves mini excavators across demanding work environments.

    Maximize Uptime. Lower the Cost Per Hour. A failed track costs more than the replacement—it costs production time. This Heavy Duty replacement track is built for contractors and fleets that need dependable machine availability, predictable wear and useful traction instead of mid-job interruptions.

    TrackTECH Advantage:

    • Continuous Steel Cord: Jointless internal steel cable construction removes splice points and reinforces the track against stretching and high-load stress.
    • Forged Steel Links: Heat-treated internal guide links support consistent sprocket engagement under repeated torque and load cycles.
    • Wear & Ground Contact: Heavy-duty lug geometry balances traction, footprint stability and long-wearing contact across everyday jobsites.
    • Controlled Travel: Tread geometry is selected for predictable forward and reverse movement during digging, trenching and repositioning.

    Confirm the Full Size Match the width, pitch and link count of the 300x52.5Nx76 against your existing track, or use the TrackTECH Rubber Track Finder to confirm fitment for your machine before ordering.

    ENGINEERED FOR THE JOBSITE

    Built Tough

    Heavy-duty replacement rubber tracks engineered for compact track loaders, tracked skid steers, mini excavators, mini track loaders, and demanding construction equipment applications.

    • 100% Virgin Rubber

      Engineered to resist chunking, tearing, and cutting in harsh, abrasive environments.

    • Continuous Steel Cords

      Jointless internal cable architecture eliminates structural weak points and maximizes overall tensile strength.

    • Drop-Forged Links

      Precision heat-treated guide lugs ensure exact sprocket engagement and prevent de-tracking under heavy side-loads.

    • Corrosion Resistant

      The internal steel framework is fully encapsulated to prevent oxidation, rust, and moisture penetration.

    • Reinforced Sidewalls

      Extra-thick vulcanized rubber and tapered edge profiles protect against curb slashing and lateral impacts from jobsite debris.

    • Low-Vibration Tread

      Optimized lug spacing and pitch geometry absorb shock, reducing undercarriage wear and minimizing cabin vibration.
