Compatible Machinery: Caterpillar Track & Forestry Excavators (320B, 320C, 322C, 322C FM, 324D FM, 324D FM LL, 325C, 325C FM, 345B II, 345B L series)

What It Does:

Serves as the heavy-duty piston rod assembly operating inside the bucket hydraulic cylinder on Caterpillar 300 series track and forestry hydraulic excavators. Connected directly to the bucket power linkage, it translates high-pressure hydraulic fluid energy into powerful linear mechanical thrust and pull forces across a 1,156.00 mm stroke to actuate bucket curling (digging/closing) and dumping (opening) motions during tough excavation, log loading, and earthmoving cycles.

Importance:

A critical kinematic load-bearing component that endures immense cyclic breakout forces, severe axial compressive loads, and dynamic shock impacts during tough rock excavation, demolition, and forestry applications. Precision-manufactured from an 86 kg high-tensile forged alloy steel structure with induction hardening, hard chrome plating, and micro-finish surface grinding, it effectively resists bending moments, surface scoring, and abrasive field wear, while ensuring tight seal engagement to prevent hydraulic fluid leaks under continuous high-pressure operations.
