NBR Oil Seal 22x34x5 AO - Double Lip Shaft Seal

Rotary Shaft Sealing for Industrial and Automotive Use

AO Double Lip Design for Improved Protection

NBR Material Resistant to Oils and Greases

Main Description

NBR oil seal 22x34x5 AO is a precision rotary shaft seal designed for effective and durable sealing in industrial applications and automotive systems. The dimensions 22x34x5 define the shaft diameter, housing diameter, and seal width, allowing accurate fitment in standard bearing housings and mechanical assemblies.

The AO double lip design features a primary sealing lip responsible for oil retention and a secondary dust lip that protects the sealing area from external contaminants. Compared to a single lip oil seal, the double lip configuration significantly improves sealing reliability and extends service life, especially in environments exposed to dust, moisture, or debris.

Manufactured from NBR rubber, this oil seal provides excellent resistance to oils and greases, fuels, and common technical fluids. NBR is widely used in shaft seals due to its stable performance, flexibility, and durability under typical operating temperatures found in machinery, gearboxes, pumps, and electric motors.

The 22x34x5 AO oil seal supports smooth shaft rotation while maintaining consistent contact pressure, ensuring effective rotary sealing with minimal friction. Properly selected and installed, it helps protect bearings, shafts, and housings, reducing wear and minimizing the risk of leakage.

This product is intended for B2B customers, maintenance departments, workshops, and machine manufacturers seeking reliable technical sealing solutions with clearly defined specifications and fast availability.
