AW4453E 130*160*17 Spring-Loaded Metal Skeleton Oil Seal | Oil & Aging Resistant Rotary Seal for Construction Equipment

This spring‑loaded oil seal is integrally molded from premium NBR nitrile rubber with built‑in garter spring, classified as a radial shaft seal. The garter spring provides constant pre‑load force on the sealing lip, keeping the lip tightly against the rotary shaft surface. It effectively retains gear oil, hydraulic oil and lubricants to prevent leakage, while blocking dust, mud‑water and grit from entering equipment housing to protect bearings and gears against wear.

Made of high‑performance NBR rubber with great oil‑resistance, wear‑resistance and anti‑aging property. Good material resilience maintains stable sealing performance even under slight shaft eccentricity. Widely used for rotary shaft sealing on excavators, loaders and other construction machinery, hydraulic motors, wheel reducers, gear reducers, gearboxes, axle hubs, agricultural machinery and industrial motors. Perfect for OEM assembly and aftermarket replacement repair.
