29556870 Sealing ring Allison spare parts

Allison 29556870 sealing rings are specialized sealing components developed and manufactured specifically for Allison series transmissions. They are manufactured in strict accordance with original equipment manufacturer (OEM) standards and are ISO 9001 quality certified. They balance sealing performance, wear resistance, and compatibility, and are widely used in heavy-duty trucks, construction machinery, special vehicles, and other equipment equipped with Allison transmissions. They precisely solve industry pain points such as seal failure and media leakage, extend equipment life, and reduce maintenance costs.
Allison 29556870 is made of high-quality polytetrafluoroethylene (PTFE) composite material and reinforced with a high-strength stainless steel spring. It has the excellent chemical corrosion resistance and low coefficient of friction of PTFE material, and relies on the spring force to compensate for the wear of the sealing lip, ensuring continuous and stable sealing performance. It can meet the sealing requirements under complex working conditions and avoid equipment failure and safety hazards caused by seal failure.
