NOK 71016038 Crankshaft Oil Seal

The NOK 71016038 is a precision-engineered crankshaft oil seal designed to prevent oil leakage from the engine crankcase while keeping contaminants out. This seal features NOK's proprietary construction with a synthetic rubber sealing lip bake-adhesioned to a metal outer ring for superior durability and reliability.

Key Features:

• Manufactured by NOK, Japan's premier oil seal specialist with over 80 years of sealing technology expertise
• Precision-molded sealing lip designed to create optimal oil film thickness for leak-free performance
• Metal-reinforced construction provides dimensional stability and resistance to installation damage
• Heat-resistant rubber compound withstands high engine temperatures and exposure to petroleum-based oils
• Spring-loaded lip design maintains consistent contact pressure throughout the seal's service life

NOK crankshaft seals utilize advanced sealing theory where the properly installed seal creates a controlled suction phenomenon that prevents oil from escaping while allowing minimal air intake. This seal is designed for rotating shaft applications and provides reliable sealing performance in demanding automotive, motorcycle, marine, and powersports engine applications.
