NATIONAL High-Performance Radial Shaft Oil Seal 70x80x8 NBR - Double Lip Rotary Seal
The NATIONAL 70x80x8 Radial Shaft Seal (Type TC/R23) is engineered for optimal performance in demanding industrial environments where precise dynamic sealing is critical. Featuring a 70mm inner diameter and an 80mm outer diameter with an 8mm width, this seal utilizes a robust nitrile rubber (NBR) compound, renowned for its excellent resistance to petroleum-based oils, hydraulic fluids, and grease. The double-lip design (main sealing lip and secondary dust lip) provides superior contaminant exclusion, safeguarding sensitive bearings and components from ingress of dust, dirt, and moisture while reliably retaining expensive lubricants within the system. Reinforced by a metallic case and internal garter spring, the seal maintains consistent radial load across the shaft surface, ensuring leak-free operation even under moderate pressure and high rotational speeds.
Investing in NATIONAL seals ensures maximized equipment uptime and significantly reduced maintenance costs associated with premature component failure. Ideal for use in gearboxes, pumps, electric motors, and general power transmission machinery, this high-durability seal provides reliable service life in temperatures ranging from -30°C to +100°C. By preventing lubricant leakage and external contamination, the 70x80x8 seal protects adjacent bearing systems, extending their operational lifespan and preserving overall machine efficiency. Choose NATIONAL quality for reliable sealing solutions that meet stringent industrial requirements.
