Floating seals are a type of dynamic seal that is designed to provide a high level of sealing performance in applications where the seal is subjected to high pressures, temperatures, and speeds. They are also well-suited for applications where the seal is exposed to dirt, dust, and other contaminants.

Floating seals are typically made of a durable material, such as nitrile rubber or polyurethane, and are available in a variety of shapes and sizes. They typically consist of two components: a seal ring and a rubber component. The seal ring is free to float between the two components, which allows it to follow the radial and thrusting motions of the shaft closely.

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

• Hydraulic cylinders
• Hydraulic pumps and motors
• Hydraulic valves
• Track rollers

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

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