1. Heavy-Duty Slewing Bearings (Rotary Tables)

• Single-Row Four-Point Contact Ball Bearings: Ideal for space-constrained applications like small excavators and welding positioners. Offers high rigidity in a compact profile.
• Double-Row Ball Slewing Rings: The industry standard for medium-to-large construction machinery and wind turbine yaw systems, providing superior load capacity.
• Three-Row Roller Slewing Bearings: Built for the heaviest duties—port cranes, shield tunneling machines, and offshore platforms—where maximum stability is non-negotiable.
• Crossed Roller Slewing Bearings: Perfect for precision robotics and medical equipment requiring zero-backlash and high rotational accuracy.

2. Enclosed Slewing Drives (Slew Gearboxes)

• Worm Gear Slewing Drives: Featuring self-locking capabilities essential for vertical axis applications like solar tracking systems and satellite antennas. Available in single-envelope and double-envelope designs for varying torque requirements (from 500 N.m to 100,000+ N.m).
• Spur Gear Slewing Drives: Optimized for high-speed rotation and efficiency in horizontal applications, commonly used in automated welding manipulators and conveyor turntables.
• Custom Voltage & Control Integration: We support DC, AC, and hydraulic motor integration, along with smart sensors for real-time position feedback.

Key Engineering Features & Quality Assurance

• Material Traceability: Every batch of steel comes with mill certificates. We strictly control carbon content and alloy composition to prevent premature fatigue failure.
• Advanced Heat Treatment: Utilizing CNC-controlled induction hardening and tempering, we achieve a precise hardness gradient (HRC 55-62 on raceways) while maintaining a tough core to absorb shock loads.
• Precision Machining: Our gear teeth are ground to DIN or AGMA standards, ensuring smooth engagement and reduced noise levels (<65 dB in standard operation).
• Sealing Technology: Multi-labyrinth seals with nitrile or fluorocarbon rubber options protect against dust, water ingress (IP66/IP67 rated), and extreme temperatures (-40°C to +80°C).
• Load Testing: Every prototype undergoes static and dynamic load testing in our certified lab before mass production.

Applications Across Industries

• Renewable Energy: Dual-axis and single-axis solar slewing drives that maximize energy capture with accurate sun-tracking algorithms.
• Construction & Mining: Swing circles for excavators, crawler cranes, and concrete pump trucks designed to handle vibration and shock.
• Industrial Automation: Rotary tables for welding positioners, packaging machinery, and radar systems requiring repeatable precision.
• Marine & Offshore: Corrosion-resistant slewing bearings for deck cranes and winch systems, treated with specialized coatings for saltwater environments.
