As a leading manufacturer specializing in precision slewing bearings since 2014, Henan San Kuang Machinery Technology Co., Ltd. leverages its extensive 10,000-30,000 square meter production facility to engineer the Double Row Ball Slewing Ring. Designed specifically for the demanding requirements of high-speed precision indexing tables, this component is a cornerstone for achieving superior rotational accuracy, rigidity, and dynamic performance in automated machinery. Our commitment to stringent quality control, backed by a comprehensive portfolio of international management system certifications including ISO9001 and ISO14000, ensures every slewing ring delivers reliable, long-lasting service in critical applications.
This slewing ring is engineered to excel where standard bearings fall short. Its core design and features directly address the challenges of modern automation:
- Enhanced Rigidity and Load Capacity: The double row angular contact ball design provides superior axial, radial, and moment load handling compared to single row designs. This increased stiffness is fundamental for maintaining table flatness and positional accuracy under high-speed indexing cycles and varying work piece weights.
- Optimized for High-Speed Operation: Precision-ground raceways and high-grade balls minimize friction and heat generation. The optimized contact angle and preload settings are tailored for smooth, low-vibration rotation at elevated speeds, which is critical for reducing cycle times and improving surface finish in machining operations.
- Superior Running Accuracy: Advanced manufacturing techniques ensure tight tolerances on raceway runout and gear tooth profile. This translates directly to exceptional indexing repeatability and minimal positional error, a non-negotiable requirement for precision assembly, inspection, and machining centers.
- Integrated Design Flexibility: The unit is available with optional internal or external spur gearing for direct drive integration. Multiple sealing options, including robust rubber seals or low-friction metal shields, protect the bearing internals from contaminants. Mounting is simplified with standardized through-hole or threaded hole patterns, accommodating various table designs.

Frequently Asked Questions (FAQ)
-
Q: What makes a double row design better than a single row for indexing tables?
A: A double row configuration significantly increases the bearing's moment stiffness and load capacity. This is crucial for indexing tables that must resist tipping moments from off-center loads and maintain flatness during high-speed starts and stops, ensuring superior positional accuracy. -
Q: Can this slewing ring handle both axial and radial loads simultaneously at high speeds?
A: Absolutely. The angular contact ball design in two rows is specifically engineered to support combined loads efficiently. The contact angle can be optimized to favor axial or radial load capacity based on your application's primary force direction. -
Q: Is the gear integral to the bearing, and what are my options?
A: Yes, the gear is machined directly onto the bearing's inner or outer ring (internal or external). This integrated design ensures perfect concentricity and eliminates alignment issues. You can choose the gear type, module, and number of teeth to match your drive pinion. -
Q: How do I ensure the bearing is properly protected in a machining environment with coolant and chips?
A> We offer multiple sealing solutions. For harsh environments, we recommend our multi-lip rubber seals or optional metal contact seals, which provide an effective barrier against fine particulates and splashing fluids, extending bearing life. -
Q: What is the typical lead time for a custom diameter or special configuration?
A: Lead times vary based on complexity and size. For standard sizes within our range, production is quicker. For fully custom designs, our engineering team will provide a schedule upon reviewing your specifications. Our efficient logistics from multiple Chinese ports help expedite global shipping. -
Q: Do you provide technical support for integrating this bearing into our table design?
A> Yes, our engineering team can provide guidance on mounting, preload selection, lubrication, and load calculations. We aim to be a technical partner to ensure optimal performance of our product in your system. -
Q: What lubrication is required, and what are the maintenance intervals?
A> The bearing is factory-filled with a high-temperature, high-speed grease. Maintenance intervals depend on operational speed, load, and environment. We provide lubrication guidelines, and optional centralized lubrication fittings can be specified for easier maintenance. -
Q: Are your products compliant with international standards for industrial machinery?
A> Our manufacturing processes are certified to multiple international management system standards, including ISO9001 for quality and ISO14000 for environmental management. The bearings are produced to meet or exceed the performance requirements typical for precision industrial machinery components.
