Part Name: Excavator Bucket Hydraulic Cylinder Group / Assembly

Technical Specifications: Bore: 160.00 mm / Stroke: 1,356.00 mm / Weight: ~355.5 kg / Hydraulic Cylinder

Compatible Machinery: Caterpillar Hydraulic Excavators (330D L, 336D, 336D L, 336D2, 336D2 L, 336E, 336E L, 336E LN, 336F L, 340D2 L, 345C, 345D, 345D L, 349D, 349D L, 349E, 349E L, 349E L VG, 349F L series)

What It Does:

Serves as the complete bucket hydraulic cylinder actuator controlling bucket curl and dump functions on Caterpillar 330D, 336, 345, and 349 series heavy hydraulic excavators. Powered by high-pressure hydraulic fluid, it extends and retracts to drive bucket digging, material retention, and dumping cycles.

Importance:

Essential for generating optimal bucket breakout force and maintaining high operational cycle speed during heavy excavation, mining, quarrying, and earthmoving tasks. Featuring a robust 355.5 kg heavy-walled barrel and high-strength forged rod structure, it effectively absorbs dynamic shock loads, rock impacts, and severe torsional stress, while advanced internal seals prevent fluid bypass under continuous heavy operation.
