What It Does:

Serves as the complete bucket hydraulic cylinder assembly mounted on the stick and bucket linkage mechanism of Caterpillar Next Gen 320 series hydraulic excavators. Powered by high-pressure hydraulic fluid, it extends and retracts to control bucket curl (closing) and dump (opening) motions, delivering the mechanical force required to dig, crowd, breakout, and discharge heavy earth and materials.

Importance:

Critical for defining bucket breakout force, rapid digging cycle times, and payload retention efficiency in general construction, utility, and heavy excavation operations. Built with a precision 115.00 mm bore and 1,104.00 mm stroke heavy-walled barrel and high-strength forged rod structure, it effectively absorbs extreme dynamic shock loads, rock impacts, and severe torsional stresses transmitted through the bucket linkage, while advanced internal seals prevent fluid bypass under continuous high-pressure operation.
