Caterpillar 1N-4428 Coupling AS – OEM-Grade Durability and Precision Fit for Heavy-Duty Applications
The Caterpillar 1N-4428 Coupling AS is a high-performance drivetrain component engineered for optimal power transmission in a wide range of Caterpillar heavy equipment. Designed specifically for models including the 57U-816 Earthmoving Compactor and various 3512, 3516, and SR4 engine-generator sets (such as 24Z-3512, 73Z-3516, 6AA-SR4, and more), this coupling ensures seamless integration and reliable operation under extreme load conditions. Manufactured with premium metallurgy and precision machining, the 1N-4428 coupling features robust dimensions tailored to withstand torsional stresses and vibration, enhancing drivetrain longevity and reducing maintenance downtime.
Technically, the 1N-4428 coupling is crafted from high-strength alloy steel with heat-treated surfaces to resist wear and fatigue. Its design accommodates axial and radial misalignment, ensuring smooth torque transfer between engine and generator components. This coupling supports critical engine-generator sets like the PTF-3512B, FDN-3516B, and GZY-3516B, maintaining consistent performance in demanding mining and earthmoving environments. By using this OEM-grade coupling, operators benefit from improved drivetrain efficiency, reduced mechanical failures, and extended equipment service life, making it an essential spare part for Caterpillar machinery maintenance.
