ZF Seal

ZF Seal

This ZF main output seal, also known as a sealing collar, is a critical replacement component for concrete mixer gearboxes. It prevents gear oil from leaking out of the main output shaft while keeping concrete dust, moisture, and debris from entering the gearbox housing. Designed to fit ZF P-Series gearboxes including the P-4300, P-5300, P-7300, and PLM 9 models, this seal ensures proper lubrication retention and extends the operational life of the mixer drive system. It features a 125mm inner diameter, 180mm outer diameter, and is constructed from durable NBR (Nitrile Rubber).
