CATERPILLAR 128-3880 Cage AS-Bearing 1283880

Caterpillar 128-3880 Cage AS-Bearing – Premium OEM-Grade Bearing Cage for Off-Highway Trucks

The Caterpillar 128-3880 Cage AS-Bearing is a critical drivetrain component engineered to ensure optimal bearing performance under extreme load conditions. Manufactured from high-grade metallurgy, this bearing cage features precise dimensional tolerances to maintain bearing alignment and reduce friction, enhancing the overall durability and operational efficiency of heavy-duty off-highway trucks. With an exact fit diameter and robust construction, the 128-3880 cage supports extended service intervals and minimizes downtime in demanding mining and construction environments.

This bearing cage is specifically compatible with a range of Caterpillar off-highway truck models, including the 89B-7EK, 789D-AX7, 789D-XDT, 789G-TR2, 789-WRL, 789C-2BW, 789D-SHH, and 789D-SPD. Its design ensures seamless integration into the drivetrain assemblies of these models, maintaining OEM specifications and performance standards. This compatibility guarantees that operators can rely on consistent performance and reduced maintenance costs when replacing worn or damaged bearing cages.

Technically, the 128-3880 Cage AS-Bearing is engineered to withstand high radial and axial loads typical in off-highway truck applications. The cage’s metallurgy is optimized for resistance to wear, corrosion, and thermal stresses, which are common in mining operations. Its precision engineering facilitates smooth bearing rotation, reducing heat generation and enhancing the lifespan of both the bearing and associated drivetrain components. This results in improved machine uptime and operational reliability.
