DKB/DKBI Series Metal Cased Dust & Oil Seals: High-Performance Sealing Solutions for Harsh Environments

Engineered for demanding industrial applications, our DKB/DKBI series of metal cased wipers combine a precision-machined metal housing with a high-grade polyurethane (PU) or nitrile butadiene rubber (NBR) sealing element. These robust seals are specifically designed to excel in contaminated environments, providing reliable protection against dust, dirt, oil, and other contaminants while maintaining optimal performance under extreme conditions.

Key Features:

Dual Material Construction: Urethane (PU) wiping edge bonded to a corrosion-resistant metal case for superior abrasion resistance and long-lasting durability.
Press-Fit Design: Easy installation into open groove housings, ensuring a secure and leak-proof fit without additional adhesives.
Wide Compatibility: Available in standard sizes (metric and imperial) to fit various hydraulic cylinders, pneumatic systems, and industrial machinery.
Extreme Environment Resistance: Withstands high pressures (up to 350 bar), temperature fluctuations (-40°C to +120°C), and exposure to chemicals, oils, and UV radiation.
Enhanced Sealing Performance: The PU/NBR element effectively wipes contaminants from piston rods, preventing ingress and extending equipment lifespan.
Low Friction Design: Reduces energy consumption and minimizes wear on moving components, ensuring smooth operation and reduced maintenance costs.

Applications:
Ideal for use in industries where equipment reliability is critical:

Construction Machinery: Excavators, loaders, bulldozers
Agricultural Equipment: Tractors, harvesters, sprayers
Material Handling: Forklifts, cranes, conveyors
Hydraulic Systems: Presses, lifts, cylinders
Automotive: Shock absorbers, braking systems
Marine and Offshore: pumps, valves, winches
