KZT stands for Komatsu Z-Ring Tandem Seal, and it is a type of hydraulic seal that is designed to provide a high level of sealing performance in high-pressure and high-speed applications. KZT seals are typically made of a durable material, such as nitrile rubber, and are available in a variety of shapes and sizes.

KZT seals are typically used in hydraulic cylinders and other hydraulic components that are subjected to very high pressures and speeds, such as those found in construction machinery. They are also well-suited for applications where the seal is exposed to dirt, dust, and other contaminants.

Here are some of the technical specifications of KZT hydraulic seals:

• Material: Nitrile rubber
• Temperature range: -40°C to +100°C (-40°F to +212°F)
• Pressure range: Up to 100 MPa (14,500 psi)
• Speed: Up to 20 m/s (66 ft/s)

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

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

KZT seals offer the following benefits for hydraulic systems in construction machinery:

• Excellent sealing performance, even at very high pressures and speeds
• Resistant to wear and tear
• Suitable for use in a wide range of hydraulic applications
• Long service life
