The KACO Oil Seal 170x190x15 DFK NBR is engineered for heavy-duty rotary shaft applications where reliable sealing performance and maximum equipment protection are essential. It is widely used in industrial gearboxes, pumps, compressors, rolling mills, mining equipment, paper machinery, marine equipment, power transmission systems, and OEM rotating machinery.

The DFK Profile incorporates a precision metal case, a spring-loaded primary sealing lip, and an auxiliary dust lip. The primary sealing lip maintains consistent contact with the shaft to retain lubricants, while the dust lip prevents dirt, moisture, dust, and abrasive contaminants from entering the sealing system. The reinforced metal case provides exceptional rigidity, dimensional stability, and secure installation in large bearing housings.

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

• Mineral oils
• Hydraulic oils
• Gear oils
• Lubricating grease
• Petroleum-based lubricants
• Moderate industrial operating conditions

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

With dimensions of 170 × 190 × 15 mm, this oil seal is commonly installed in large industrial gearboxes, pumps, heavy-duty electric motors, conveyors, crushers, mixers, steel processing equipment, and OEM machinery requiring reliable metric rotary shaft sealing.
