Shank Bushing 15178308 | High-Density Bronze Bushing for Hydraulic Rock Drills

High-Density Bronze Shank Bushing for Hydraulic Rock Drills
Engineered for extreme underground mining conditions, this shank bushing ensures reliable load-bearing in high-vibration hydraulic rock drill applications. Constructed from 90-10 tin bronze (CuSn10P) with a nickel-plated surface, it withstands continuous dynamic loads up to 20 MPa while resisting abrasion and corrosion in harsh environments .

Technical Specifications & Design
The bushing features a 16 mm inner diameter (ISO 4385 tolerance ±0.05 mm) and 24 mm outer diameter, designed for secure mounting in hydraulic cylinder assemblies and drill rig components. Its HB120 hardness provides optimal balance between structural integrity and wear resistance, reducing the risk of deformation under repetitive impact loads . The nickel-plated coating (5 μm thickness) passes 96+ hours of salt spray testing (ISO 9227), ensuring long-term performance in wet or corrosive mining environments .
