High-Precision External Gear Slewing Bearings for Heavy-Duty Engineering Applications

At LIYUANDRIVE, we specialize in the design and manufacture of high-performance External Gear Slewing Bearings. Unlike internal gear solutions, our external gear rings are engineered for specific mechanical configurations where the drive pinion operates on the outer circumference, offering superior accessibility and high-torque transmission for specialized engineering machinery.

Versatile Solutions for Global Engineering & Lifting Brands

Our External Gear Slewing Rings are the preferred choice for original equipment manufacturers (OEM) and high-quality replacements across a variety of industrial sectors. We provide precision-engineered bearings compatible with the technical specifications of leading global brands in the following fields:

• Mobile & Truck Cranes: Compatible with structural requirements for Sany, XCMG, Zoomlion, Liebherr, Tadano, and Grove.

• Tower Cranes & Construction Hoists: Reliable rotation solutions for Potain, Liebherr, and Yongmao.

• Rotary Drilling Rigs: Heavy-duty external gear rings for Bauer, Casagrande, and Mait.

• Aerial Work Platforms (AWP): Precision bearings for Genie, JLG, Haulotte, and Dingli.

• Marine & Offshore Cranes: Salt-spray resistant solutions for Palfinger, MacGregor, and Heila.

• Solar Tracking Systems: Specialized slewing drives and bearings for large-scale solar arrays (Single-axis & Dual-axis trackers).

• Other Applications: Concrete pumps (Putzmeister, Schwing), Port machinery, Forest equipment, and specialized material handling systems.

Technical Superiority of LIYUANDRIVE External Gear Rings

To ensure long-term reliability in harsh working environments, our External Gear Slewing Bearings undergo advanced manufacturing processes:

1. Induction Hardened External Teeth: We apply localized induction hardening to the gear teeth (typically 50-60 HRC) to minimize wear and prevent tooth breakage under peak loads.

2. High-Strength Forging: Utilizing premium alloy steels like 42CrMo or 50Mn, our rings offer exceptional fatigue resistance.

3. Advanced Sealing Technology: Protects the raceway from dust, water, and contaminants, extending the service life in outdoor construction sites.

4. Optimized Bolt Hole Patterns: Available in standard and customized configurations for easy installation and secure mounting.

As a dedicated Slewing Bearing Manufacturer, we understand that precision is non-negotiable. Every unit is subjected to rigorous ultrasonic testing and dimensional inspection to ensure it meets the highest international standards.
