Core details

Function

This piston is a critical moving component inside a hydraulic cylinder. It converts hydraulic fluid pressure into linear mechanical force and motion, powering machine functions such as boom lifting, arm digging, bucket curling, and track movement.

Design & Construction

1.Precision-machined to Komatsu’s exact specifications for a tight, leak-proof fit within the cylinder bore.

2.Typically made from high-strength, wear-resistant steel or alloy to withstand extreme hydraulic pressures, heavy loads, and continuous reciprocating motion.

3.Features precision grooves to accommodate piston seals (e.g., piston rings, wiper seals) that ensure hydraulic fluid sealing and prevent internal leakage.

Compatibility

It is engineered to fit specific Komatsu equipment models requiring this part number. Using this genuine Komatsu piston guarantees perfect dimensional match, optimal hydraulic system performance, and long service life—avoiding issues like seal failure, fluid loss, or reduced cylinder efficiency common with non-OEM alternatives.
