Rotary Shaft Seal 30x47x4 NBR SC Oil Seal Single Lip

Main Description

The Rotary Shaft Seal 30x47x4 NBR SC Oil Seal Single Lip is a high-quality industrial sealing component designed to protect rotating mechanical systems against oil, grease, and operating fluid leakage. Manufactured from durable NBR rubber, this rotary shaft oil seal is intended for industrial machinery, pumps, electric motors, gearboxes, automotive systems, and compact mechanical drives requiring reliable sealing performance and long operational durability.

The 30x47x4 mm SC-type oil seal features a rubber-coated outer diameter and a single sealing lip optimized for smooth rotary shaft operation. The SC construction provides effective sealing performance while maintaining low friction and stable operation in applications exposed to continuous shaft rotation.

The NBR material offers excellent resistance to mineral oils, greases, fuels, and common hydraulic fluids used in industrial and automotive systems. Due to its durability and versatility, NBR rotary shaft seals are among the most commonly used sealing solutions for industrial power transmission systems and rotating machinery.

The compact dimensions of the 30x47x4 mm oil seal make it suitable for applications where installation space is limited while maintaining reliable protection against lubricant leakage and external contamination.
