Rock Penetration Abrasion-CE
The Rock Penetration Abrasion-CE is a high-strength excavator bucket pin designed for use in extreme digging and loading environments where abrasion and impact are constant. Built to perform under the harshest conditions, this pin delivers unmatched durability and prolonged service life across a wide range of machines.
Material & Construction
Each Rock Penetration Abrasion-CE pin is manufactured using heat-treated, high-tensile alloy steel, engineered to withstand continuous pivoting motion under heavy loads. The surface is treated with a chromium or nickel plating or case-hardened finish to minimize wear and resist corrosion in rocky or abrasive environments.
Key material features include:
Core Hardness: 38–45 HRC for strength and shock absorption
Surface Hardness: 55–62 HRC for superior wear resistance
Precision Machining: Tolerance control for perfect pin-to-bush fit
Optional Coatings: Anti-corrosion plating or dry-lube finishes for extended performance
Applications
These pins are ideal for:
Excavators working in high-abrasion sites (quarries, rocky soil, demolition)
Buckets, link arms, and booms under constant motion
Heavy construction, earthmoving, and mining equipment
