Heavy-Duty Lower frame Bushing for Single-Cylinder Cone Crushers
The Silent Guardian of Crusher Foundations | NMS ∙ Metso ∙ Sandvik Compatible

Extend your crusher’s operational life and minimize vibration-induced wear with our high-performance Lower frame Bushing – a critical interface component designed for seamless fit in NMS, Metso, and Sandvik single-cylinder cone crushers. This precision bushing absorbs eccentric motion stresses, protecting your crusher’s structural integrity in high-tonnage applications.

Multi-Brand Precision: OEM-e dimensions ensure perfect compatibility with NMS, Metso, and Sandvik crusher lower frames.

Ultimate Wear Resistance: Forged bronze alloy (CuZn25A16Fe3Mn3) withstands extreme pressure (300+ MPa) and abrasive slurries without galling or deformation.

Vibration & Misalignment Control: Self-lubricating design dampens harmonic resonance, preventing cracks in frame castings and bearing seats.

Extended Service Life: 2–3× longer lifespan than standard bushings in granite/iron ore crushing.

Thermal Stability: Maintains dimensional accuracy from -30°C to 180°C (-22°F to 356°F).

Cost Efficiency: Prevents cascading damage to shafts, gears, and frame assemblies.

Dynamic Load Absorption: Distributes eccentric forces evenly across the crusher foundation.

Embeddability: Micro-surface conformity traps contaminants to protect shaft journals.

Corrosion Resistance: Ideal for coastal mines and high-moisture processing plants.

Zero-Maintenance: Pre-lubricated for lifetime operation (excludes extreme contamination).

Where Motion Meets Endurance.
Trust our Lower frame Bushing to be the unyielding anchor between power and stability.
