Double-row different-diameter ball slewing ring (02 Series)
This type of slewing bearing features a unique three-ring design combined with double-row, different-diameter balls. The steel balls and spacers can be inserted directly into the upper and lower raceways for convenient open assembly, while the two rows of balls with varying diameters scientifically distribute the applied loads.
Its core advantage lies in its powerful load-bearing performance:
- Excellent Load Capacity: Both upper and lower raceways adopt a 90° load angle, allowing the bearing to simultaneously handle massive axial forces and tilting moments while ensuring stable operation.
- Flexible Design Adaptability: For working conditions where radial force is significant (>10% of the axial force), the raceways can be custom-engineered to ensure absolute reliability.
- Robust Structural Foundation: Featuring large axial and radial dimensions, the product has an exceptionally rigid structure built specifically for continuous, heavy-duty operations.
Consequently, it is the ideal choice for slewing systems in medium-to-large handling and lifting machinery, such as tower cranes and truck cranes.

Details
1. Oil Holes: n₁ represents the number of lubrication holes. For your convenience during equipment maintenance, the specific locations of the oil holes can be customized based on your actual application requirements. (Grease nipple: M10×1, Compliance standards: JB/T 7940.1 to JB/T 7940.2)
2. Threaded Holes: n-∅ indicates the mounting holes, which are through-holes (clearance holes) by default. These can be modified to threaded holes to match your specific mounting and securing plan. (Thread diameter: M, Thread depth: 2M)
3. Dimensional Tolerances: The product specifications listed in the table represent our standard products, where both inner and outer diameters carry standard un-tolerated (free) tolerances. If your host equipment requires a specific fit with the slewing bearing, please specify your requirements so we can customize production for you.
4. Non-Standard Customization: The list contains our standard product series. We fully understand the unique requirements of different application scenarios. Whether you require a specialized structural design, unique dimensions, specific material properties (such as low-temperature or corrosion resistance), higher precision grades, or any other non-standard customization, our engineering and technical team is ready to provide you with professional solutions.
