The KACO Grease Seal 50x64x10/13 DF NBR is specifically engineered for grease-lubricated rotating equipment where preventing grease leakage and blocking contaminants are essential for maximizing bearing life and equipment reliability. It is widely used in wheel hub assemblies, bearing housings, electric motors, agricultural machinery, trailers, industrial machinery, conveyor systems, and OEM rotating equipment.

The DF Profile features a precision metal case, a spring-loaded primary sealing lip, and an auxiliary dust lip. The primary sealing lip securely retains grease inside the bearing housing, while the dust lip effectively prevents dust, dirt, water, mud, and abrasive particles from entering the lubrication system. The precision metal case ensures dimensional stability and a secure press-fit installation.

Manufactured from premium NBR (Nitrile Butadiene Rubber), this grease seal provides excellent resistance to:

• Bearing grease
• Mineral oils
• Hydraulic oils
• Gear oils
• Petroleum-based lubricants

NBR offers excellent flexibility, abrasion resistance, and durability, making it one of the most widely used sealing materials for grease-lubricated bearing applications in industrial and automotive equipment.

With dimensions of 50 × 64 × 10/13 mm, this grease seal is commonly installed in wheel hubs, bearing housings, electric motors, agricultural machinery, trailers, conveyor systems, industrial gearboxes, and OEM machinery utilizing metric shaft systems.
