DKB is a type of hydraulic dust seal that is commonly used in construction machinery. It is made of nitrile rubber (NBR) and has a metal frame. DKB seals are designed to prevent dust, dirt, and other contaminants from entering hydraulic systems. They are also resistant to wear and tear, making them ideal for use in harsh environments.

DKB seals are typically used in piston rods and other hydraulic cylinders. They are also used in some hydraulic pumps and motors. DKB seals are available in a variety of sizes to fit a wide range of hydraulic applications.

Here are some of the technical specifications of DKB hydraulic dust seals:

• Material: Nitrile rubber (NBR)
• Metal Frame: Steel
• Temperature range: -40°C to +100°C (-40°F to +212°F)
• Pressure range: 0 to 40 MPa (0 to 5800 psi)
• Speed: Up to 10 m/s (33 ft/s)

DKB seals are used in a variety of construction machinery applications, including:

• Excavators
• Bulldozers
• Backhoes
• Wheel loaders
• Skid steer loaders
• Cranes
• Concrete mixers
• Asphalt pavers

DKB seals are an important component of hydraulic systems in construction machinery. They help to ensure that hydraulic systems operate reliably and efficiently, even in harsh conditions.

Here are some of the benefits of using DKB hydraulic dust seals in construction machinery:

• Excellent dust sealing ability
• Resistant to wear and tear
• Suitable for use in a wide range of hydraulic applications
• Long service life

DKB hydraulic dust seals are a reliable and cost-effective way to protect hydraulic systems in construction machinery from dust, dirt, and other contaminants.
