R210LC R215 R225-9 R235LC-R9 R220LC-9S Arm Cylinder Seal Kit 31Y1-28790 for Hyundai Excavators Repair
As a specialized manufacturer of excavator hydraulic seal kits, we provide high-precision, factory-grade replacements for critical Hyundai machinery. The Arm Cylinder (or Stick Cylinder) on the Hyundai R210LC, R215, R225-9, R235LC-R9, and R220LC-9S series excavators is constantly in motion, demanding a robust sealing solution. Our ARM SEAL KIT, often cross-referenced with OEM part number 31Y1-28790, is the reliable, factory-direct solution for wholesale buyers seeking superior quality and value.
The Critical Need for a Premium 31Y1-28790 Arm Seal Kit
The Arm Cylinder’s function is vital for the excavator’s digging and loading capabilities. Seal failure in this cylinder can lead to:
1.Loss of Control: Internal leakage causes the arm to drift or creep, making precise operation impossible and potentially hazardous.
2.Premature Wear: Contaminants entering the cylinder due to failed wiper seals accelerate wear on the piston rod and cylinder bore, leading to expensive cylinder replacement.
3.Reduced Productivity: Any hydraulic inefficiency translates directly into slower cycle times and decreased overall machine productivity.
Our 31Y1-28790 Arm Seal Kit is a complete, multi-component solution engineered for maximum durability and sealing performance, restoring the cylinder to its original specifications.
