Heavy-duty 20 teeth torsional coupling assembly for CAT grader transmission system, ensuring stable torque transfer and vibration damping.
The YNF18095 torsional coupling assembly 422-2480 for CAT Caterpillar grader is engineered for heavy-duty transmission systems requiring stable torque transfer and effective vibration absorption. Designed with a 20-tooth precision interface, it ensures accurate engagement between drivetrain components.
This coupling assembly is manufactured using high-strength alloy steel combined with torsional damping elements, allowing it to absorb mechanical shocks and reduce stress on the grader’s transmission system. It significantly improves operational smoothness and helps extend the lifespan of connected drivetrain components.
As a critical part of the CAT grader transmission system, it plays an essential role in maintaining stable power delivery under continuous heavy load conditions.
YNF Machinery supplies this component as an OEM-equivalent replacement for CAT 422-2480, widely used by equipment maintenance companies, fleet operators, and aftermarket distributors requiring consistent quality and reliable supply for global B2B procurement.
