Komatsu and Hyundai excavator parts include bushings, pistons, hydraulic cylinders, arms, slewing gears, and chassis. Bushings are made of hardened chrome steel with wear-resistant coating and can withstand hydraulic pressures between 200 to 500 bar. Pistons, made from aluminum alloy or durable steel, can operate at temperatures of 120 to 150 degrees Celsius and handle hydraulic torque above 400 Nm. Arms and chassis are constructed from steel with tensile strength of 550 to 700 MPa to resist impact and fatigue from repeated loading.
Hydraulic cylinders have internal diameters of 80 to 200 mm and stroke lengths of 500 to 1200 mm. Slewing gears are manufactured from hardened steel with dimensional accuracy of ±0.05 mm to ensure smooth and uniform power transmission. Seals and O-rings are made from NBR or Viton, offering high chemical and thermal resistance. These components are optimized to reduce vibration, increase durability, and improve fuel efficiency in heavy machinery.
