A Washing Machine Shaft Oil Seal is a critical component designed to prevent water leakage from the tub into the bearings and motor assembly. Located on the tub shaft, it acts as the primary barrier against hot water, detergent, and debris during high-speed spin cycles.
PQK manufactures these seals using specialized elastomer compounds like NBR and FKM to withstand thermal expansion and dynamic rotational stress. For distributors seeking reliable replacements, our wholesale shaft oil seal product line offers precise fitment for major washing machine brands, ensuring reduced maintenance costs and extended appliance longevity.
