GRN 155x195x16.5/18 NBR Cassette Seal Rotary Shaft Seal

Heavy-Duty GRN Cassette Seal for Extreme Industrial and Off-Highway Applications

The GRN 155x195x16.5/18 NBR Cassette Seal is a heavy-duty rotary shaft sealing solution developed for rotating equipment operating in harsh environments where mud, water, dust and abrasive contaminants are continuously present. Unlike conventional radial shaft seals, the GRN cassette seal features an integrated multi-lip sealing system and a dedicated wear sleeve, providing superior contamination protection and extended component life. Manufactured from premium NBR (Nitrile Butadiene Rubber), it offers excellent resistance to mineral oils, greases and hydraulic fluids, making it an ideal solution for demanding industrial and mobile equipment.

This GRN product is positioned as an independent industrial sealing solution, emphasizing the GRN Cassette Seal product family and avoiding competition with other manufacturer-specific product ranges.
