Cone crushers
Bearing vibration, lubrication and eccentric assembly condition monitoring
Solutions for cone crushers
We match the right system to your site goals and budget
SDT Ultrasound Solutions
Ultrasound + VibrationThe primary tool for cone crushers. Ultrasonic monitoring detects wear in the main shaft and eccentric bearings 4–12 weeks ahead of failure.
- SDT340 — multi-channel ultrasound with signal recording and long-term trending
- LUBExpert — precise grease dosing at each point (−30% consumption)
- SDT270 — fast shift rounds without stopping equipment
- Detection of pitting on gearbox and gear mesh teeth
- Inspection on running equipment via adapters on bearing caps
Bently Nevada Orbit 60 / DCM
Permanent MonitoringContinuous 24/7 vibration monitoring for critical cone crushers. Automatic shutdown when alarm thresholds are exceeded.
- Orbit 60 / DCM — permanent main shaft bearing monitoring
- Proximity probes for the eccentric assembly
- System 1 — management and analytics platform
- Alarm levels with automatic protection and trip
- API 670 compliance for critical machinery
Artesis e-MCM
AI · Portable / PermanentAI diagnostics of the cone crusher drive from the electrical signature. Eccentric wear and load changes appear in motor current patterns.
What the system monitors
Critical nodes and detectable defects with lead-time indicators
Main shaft bearing
Carries the full crushing load. Diameter up to 1000 mm, hundreds of tonnes of continuous load.
Eccentric shaft and bearings
Generates the gyratory motion of the crushing head. Wear increases the crushing gap.
Drive and gearbox
Bevel or spur gear drive. Ultrasonic inspection of gear teeth.

Successful deployments
SDT340 recorded a 9 dB rise in ultrasonic level at the main shaft bearing. Bearing replacement during a planned outage prevented a catastrophic failure costing $800K.
Artesis detected abnormal drive current patterns consistent with eccentric assembly wear. Repairs were completed before full destruction of the unit.
Orbit 60 / DCM installed on the most critical crusher in the line. Automatic trip activated at a vibration peak, preventing metal-to-metal contact.
