Product Overview

The 1261880 Hydraulic Cylinder Seal Kit is primarily used for Caterpillar excavator hydraulic cylinders. This kit includes various seals designed to ensure the efficient operation and longevity of hydraulic systems.

Main Components

1. Guide Rings: Guide the piston rod, preventing direct contact with the cylinder wall and reducing wear.
2. Support Rings: Provide additional support to prevent seal deformation under high pressure.
3. O-Rings: Used for static and dynamic sealing to prevent hydraulic oil leakage.
4. Skeleton Oil Seals: Seal rotating shafts to prevent oil leakage and external contaminants from entering.
5. Dust Rings: Prevent external dust and debris from entering the hydraulic cylinder, protecting the seals and hydraulic oil.

Materials

The seal kit is made from various high-quality materials, including:

• NBR (Nitrile Rubber): Good oil resistance, suitable for general hydraulic oil.
• PTFE (Polytetrafluoroethylene): Extremely low friction coefficient and excellent chemical resistance.
• ACM (Acrylic Rubber): Good high-temperature and oil resistance.
• VMQ (Silicone Rubber): Excellent high-temperature and cold resistance.
• FKM (Fluoro Rubber): Excellent high-temperature, oil, and chemical resistance.
• HNBR (Hydrogenated Nitrile Rubber): Good high-temperature, oil, and wear resistance.
• EPDM (Ethylene Propylene Rubber): Good weather and ozone resistance.

Performance Characteristics

• Excellent Sealing Performance: Ensures efficient operation of the hydraulic system and prevents hydraulic oil leakage.
• High Wear Resistance: Extends the service life of the seals and reduces maintenance frequency.
• Low Friction: Reduces energy loss and improves system efficiency.
• Chemical Stability: Suitable for various hydraulic oils and working environments.
• High Temperature and Aging Resistance: Maintains stable performance in high temperatures and harsh environments.

Working Conditions

• Pressure: Can withstand working pressures up to 690 bar (10,000 psi).
• Temperature Range: Suitable for working environments from -40°C to 120°C.

Application

This seal kit is widely used in the hydraulic systems of Caterpillar excavators, ensuring reliable operation under various working conditions.
