The KACO 56x75x22.5/01 COMBI NBR Oil Seal is designed for demanding applications where conventional oil seals cannot provide sufficient protection. The COMBI (Cassette Seal) design combines multiple sealing lips with an integrated precision wear sleeve to create a complete sealing system capable of operating under heavy contamination and continuous service.

Unlike standard rotary shaft oil seals, the COMBI Profile provides multiple sealing barriers that effectively retain lubricants while preventing water, mud, dust, sand, and abrasive particles from entering the bearing system. The integrated wear sleeve also protects the shaft from wear, eliminating the need for separate shaft repair sleeves in many applications.

Manufactured from premium NBR (Nitrile Butadiene Rubber) together with precision steel components, this seal offers excellent resistance to:

• Mineral oils
• Gear oils
• Differential oils
• Hydraulic oils
• Lubricating grease
• Petroleum-based lubricants

The COMBI cassette seal is widely used in heavy-duty vehicles and industrial equipment where long service life and maximum contamination protection are essential.

With dimensions of 56 × 75 × 22.5/01 mm, this seal is commonly installed in truck wheel hubs, axle assemblies, agricultural machinery, construction equipment, mining machinery, forestry equipment, trailers, and OEM heavy-duty rotating equipment.
