This is an aftermarket replacement for the Corteco 82020496NO NBR RWDR-Cassette Seal, engineered to deliver reliable sealing performance in various demanding applications. This high-quality compatible seal features precise dimensions of 142mm inner diameter, 170mm outer diameter, and a width of 15/16mm, ensuring a snug and effective fit. Manufactured from durable NBR (Nitrile Butadiene Rubber), it offers excellent resistance to oils, greases, and common agricultural and industrial fluids, making it suitable for harsh operating environments. Cassette seals are advanced rotary shaft seals specifically designed for heavy-duty applications, such as those found in agricultural machinery, construction equipment, and industrial gearboxes or axles. Their multi-lip design and integrated sealing elements effectively prevent lubricant leakage while simultaneously protecting internal components from ingress of dirt, dust, mud, and water. This robust construction extends the lifespan of bearings and other critical parts by maintaining a clean and lubricated environment. Choosing this aftermarket alternative provides a cost-effective solution without compromising on the essential function of protecting your machinery's vital systems.
