Rotary Shaft Seal 4x10x4 ZBA Oil Seal

Main Description

The Rotary Shaft Seal 4x10x4 ZBA is a precision radial oil seal designed for reliable sealing of rotating shafts in industrial, automotive, and mechanical drive applications. Manufactured from high-quality NBR (nitrile butadiene rubber), this seal provides effective containment of lubricants and protection against contaminants, dirt, and moisture in rotating and reciprocating systems, fulfilling core sealing requirements between rotating components and static housings.

With exact dimensions 4x10x4 mm (inner diameter x outer diameter x thickness), this oil seal is suitable for compact shafts in electric motors, gearboxes, pumps, compressors, and other machinery where space is limited and sealing performance is critical. The ZBA configuration typically includes an elastomer outer jacket, ensuring a secure fit in the bore and consistent sealing pressure over extended service life.

NBR material offers excellent resistance to mineral oils, greases, and standard hydraulic fluids, combined with good wear and abrasion resistance under normal operating conditions. This makes the Rotary Shaft Seal suitable for a variety of industrial lubrication environments where fluid retention and contaminant exclusion are essential for equipment reliability and uptime.

The seal’s design ensures stable performance with minimal friction, enabling longer service intervals and lower maintenance costs. It is widely used as a shaft sealing solution in assembly lines, manufacturing equipment, automotive repair and service operations, and other systems requiring durable oil retention sealing solutions. The Rotary Shaft Seal 4x10x4 ZBA aligns with common search terms used by engineers and technical buyers seeking radial oil seals, shaft seals, NBR rotary seals, and industrial sealing components.

FAQ - Frequently Asked Questions
