GRN COMBI 165x190x17 mm NBR Cassette Oil Seal

Heavy-Duty Cassette Oil Seal for Extreme Industrial Environments

The GRN COMBI 165x190x17 mm is a premium cassette oil seal developed for rotary shaft applications operating in harsh environments where conventional radial shaft seals cannot provide adequate protection. Its advanced cassette construction combines multiple sealing lips, an integrated wear sleeve, and a heavy-duty sealing system that effectively prevents the ingress of dirt, dust, mud and water while retaining lubricants inside the assembly.

Manufactured with a high-quality NBR (Nitrile Butadiene Rubber) sealing element, the seal provides excellent resistance to mineral oils, greases and hydraulic fluids, ensuring reliable long-term operation in industrial and mobile machinery.
