29558048 Clutch Hub Allison spare parts

29558048 Clutch Hub Allison spare parts

The Allison 29558048 clutch hub, as a core component of the Allison original clutch system, focuses on solving the core needs of power transmission, torque bearing, and shifting. It is widely used in the transmission systems of Allison’s full range of heavy-duty automatic transmissions and various heavy commercial vehicles, engineering and mining machinery. The product strictly follows the original manufacturer’s production standards, from the selection of 42CrMo alloy steel ingots, precision forging, normalizing and tempering, five-axis precision milling, internal gear ring carburizing and quenching, ion nitriding strengthening, and wear-resistant bushing press-fitting, to full dimensional inspection, gear engagement accuracy testing, wear resistance testing, and temperature and pressure resistance testing, with full quality control throughout the entire process. It eliminates problems such as poor power transmission, shifting jerks, hub wear, and cracking caused by forging defects, insufficient machining accuracy, improper heat treatment, and gear engagement deviations. It is suitable for complex working conditions such as heavy load, high-frequency shifting, severe vibration, and high temperature, and meets the processing and quality standards of GB/T 3077-2015, GB/T 1184-2008, ISO 9001, and CE.
