2P-1272 Caterpillar belt plays a key role in the equipment's power transmission system. It efficiently transmits power by connecting the engine crankshaft with water pumps, generators and other components, ensuring synchronous operation of auxiliary equipment. It adopts a composite structure of neoprene base material and high-strength polyester cords, with a tensile strength of 15MPa, excellent resistance to tensile deformation, and can work stably in -30℃ to 80℃ environment, avoiding slippage or breakage caused by temperature changes.
The belt surface adopts a toothed design to increase friction with the pulley, with a transmission efficiency of over 95%, compatible with Caterpillar 312B, 320C, 330D series excavators and C7.1, C9 engines. Its perimeter error is ≤1mm, with precise width, no frequent adjustment after installation, reducing maintenance costs and extending the replacement cycle to over 2000 hours (under normal working conditions).
