The KACO 40x70x10 DF NBR Oil Seal is engineered for rotary shaft applications requiring reliable sealing performance and effective protection against external contaminants. It is widely used in industrial gearboxes, hydraulic pumps, electric motors, compressors, agricultural machinery, construction equipment, machine tools, 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 retains lubricants inside the equipment, while the dust lip prevents dust, dirt, moisture, and abrasive particles from entering the sealing area. The metal case provides excellent dimensional stability and secure installation in the housing.

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

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

NBR provides excellent abrasion resistance, flexibility, and durability, making it one of the most widely used sealing materials for industrial rotary shaft applications.

With dimensions of 40 × 70 × 10 mm, this oil seal is commonly installed in industrial gearboxes, hydraulic pumps, electric motors, compressors, agricultural equipment, conveyor systems, and OEM machinery requiring metric rotary shaft seals.
