563-8599 SEAL GP-DUO for CAT 785/789/795F XQ

Features & Benefits

• Duo-Cone Seal Design: 563-8599 uses a metal-to-metal sealing interface designed to protect final-drive components from external particle intrusion.
• Reliable Oil Sealing: The Duo-Cone design helps maintain an oil-tight seal during continuous rotation and demanding operating conditions.
• Contamination Protection: Helps prevent dust, dirt and other abrasive particles from entering the final-drive system and damaging internal components.
• Heavy-Duty Construction: Designed for high-load off-highway applications where final-drive components experience significant mechanical stress.
• Supports Misalignment: Cat states that Final Drive Duo-Cone Seals maintain an oil-tight seal during rotation even where misalignment may occur.
• Toric Element Support: Rubber toric elements help position the metal sealing rings and maintain controlled sealing pressure during operation.
• Replacement Solution: Suitable for replacing worn or leaking final-drive seals during scheduled maintenance or drivetrain overhaul.
