Heavy-Duty Bucket Cylinder Seal Kits: High-Pressure Repair for Excavator Buckets

Is your excavator losing its digging power or showing signs of a sinking bucket? A worn-out bucket cylinder seal kit is often the culprit, leading to internal pressure loss and decreased efficiency. The bucket cylinder is constantly exposed to dirt, rocks, and intense shock loads. BeeSpareParts offers high-performance aftermarket bucket seal kits designed to withstand these harsh conditions and restore your machine’s hydraulic precision.

Our compatible seal solutions are engineered to fit for Caterpillar (CAT), Komatsu, and John Deere equipment. Manufactured using premium 95 Shore A Polyurethane (PU) and high-grade Nitrile (NBR), these kits provide excellent resistance to extrusion and heat. Whether you need a replacement for CAT 320D, Komatsu PC200, or Volvo EC210, our precision-fit kits include everything from rod seals and wipers to piston seals, ensuring a complete, leak-proof rebuild that meets or exceeds OEM performance standards.

Key Performance Benefits:

• Restore Digging Precision: High-quality piston seals eliminate bucket drift, ensuring your bucket stays in position.

• Superior Contamination Protection: Reinforced wiper seals prevent dirt, grit, and water from entering the hydraulic system.

• Reliable Compatibility: Direct-fit kits designed as a replacement for major brands like Hitachi, Kobelco, and Doosan.
