High-Torque Pinion Assembly for Single-Cylinder Cone Crushers
The Heartbeat of Your Crusher's Drive System | NMS ∙ Metso ∙ Sandvik Compatible

Maximize power transmission reliability and eliminate unplanned downtime with our fully integrated Pinion Assembly – precision-engineered for exact fitment in NMS, Metso (HP/GP Series), and Sandvik (CH/CS Series) single-cylinder cone crushers. This critical assembly delivers unmatched torque efficiency and contamination resistance in the most abrasive mining and quarry environments.

Multi-Brand Plug-and-Play: OEM-equivalent dimensions and spline profiles for direct replacement in NMS, Metso, and Sandvik crushers – no modifications.

Ultimate Wear Resilience: Case-hardened alloy steel gears (ISO 6336 Grade ME) withstand 1,500+ MPa bending stress and micropitting in high-silica environments.

Vibration-Free Operation: Dynamically balanced to ISO 1940 G2.5 standard (residual imbalance ≤0.5 g·mm/kg).

Triple-Seal Defense: Labyrinth seals + lip seals + grease-purged barriers block 99.9% of dust/slurry ingress (validated per ISO 4406:2021).

Thermal Stability: Maintains gear mesh precision from -30°C to 120°C (-22°F to 248°F).

60% Faster Replacement: Pre-assembled unit reduces downtime to ≤3 hours versus component-level rebuilds.

Zero-Maintenance Bearings: Pre-lubricated, sealed-for-life roller bearings (50,000+ hour L10 rating).

Anti-Galling Splines: Phosphated surface treatment prevents cold welding under high-torque loads.

Impact Protection: 10mm thick housing deflects tramp metal and flying debris.

Corrosion Defense: Zinc-nickel plating for saltwater/chemical exposure.

Power Transmitted. Perfection Delivered.
Trust our Pinion Assembly to drive productivity – engineered for 100,000+ hours of zero-failure operation.
