The DPH Oil Seal 120x160x17 SYSTEM 500 NBR is a heavy-duty cassette seal specifically designed for applications where standard oil seals may not provide sufficient protection against contamination and environmental exposure.

Unlike conventional rotary shaft oil seals, SYSTEM 500 cassette seals incorporate multiple sealing elements, an integrated spring-loaded primary sealing lip, anti-pollution sealing lips, and reinforced metal construction. This advanced design significantly improves resistance against dirt, water, mud, abrasive particles, and other contaminants commonly found in demanding industrial and off-road environments.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing elements offer excellent resistance to oils, greases, hydraulic fluids, and industrial lubricants while maintaining flexibility and durability under continuous operation. Cassette seals are commonly selected for applications where equipment reliability and contamination protection are critical.

The 120 x 160 x 17 mm size is frequently used in wheel hubs, axles, agricultural machinery, construction equipment, mining machinery, industrial gearboxes, and rotating equipment exposed to severe environmental conditions.
