High-Precision Ball Nut for Rock Drill Jumbos
Engineered for the precise linear motion of rock drill jumbo feed mechanisms, this ball nut delivers exceptional accuracy and durability in harsh mining environments. Its C3 precision class ensures consistent performance under heavy loads and vibration, making it critical for efficient drilling operations .

 

Technical Specifications & Design
  • Core Performance Traits:
    • C3 Precision Class: Compliant with ISO 3408 standards, offering 0.01mm lead accuracy for precise drill positioning. This level of precision reduces material waste in tunneling and mining applications .
    • High Load Capacity: 50kN dynamic load and 100kN static load ratings support the heavy forces exerted by drill arm movements, ensuring long-term reliability .
    • Corrosion Resistance: Chrome plating protects against moisture and mineral oils, while the nitrile rubber seal prevents contaminant ingress in dusty mining conditions .

 

Performance Advantages
  • Smooth Operation:
    • Ground thread surfaces (Ra 0.8μm) minimize friction, reducing wear on mating screws and extending service life by 30% compared to standard nuts .
    • Integral grease nipple allows easy lubrication, maintaining performance even in remote mining locations.
  • Environmental Resilience:
    • Operates reliably from -30°C (cold underground mines) to +100°C (high-friction areas), with no loss of precision or load capacity .

 

Applications
  • Rock Drill Jumbos: Essential for feed mechanisms that control drill bit advancement, ensuring accurate hole placement.
  • Mining Equipment: Compatible with tunnel boring machines and hydraulic drill rigs requiring precise linear motion.
  • Industrial Machinery: Suitable for heavy-duty linear actuators in construction and material handling equipment.
