As a leading manufacturer established in 2014, Henan San Kuang Machinery Technology Co., Ltd. specializes in providing high-performance, precision-engineered slewing bearings for the global industrial market. Operating from a modern facility spanning 10,000-30,000 square meters in Luoyang, China, we combine extensive manufacturing expertise with a commitment to quality, evidenced by our comprehensive certifications including ISO9001 and ISO14000. Our Customizable Single Row Ball Slewing Bearing with Specific Bore Diameter and Bolt Pattern represents the culmination of this expertise, offering OEMs and machinery builders a reliable, application-tailored solution designed to enhance the performance and longevity of their rotating equipment.
This bearing is engineered to serve as the critical rotational interface in demanding applications. Its core value lies in its customizability – we don't offer a one-size-fits-all product. Instead, we work closely with clients to adapt the bore diameter and bolt hole circle pattern to their exact mounting requirements, ensuring seamless integration into existing designs and eliminating costly adapter plates or modifications. This flexibility, backed by robust construction, translates directly into reduced assembly time, improved structural integrity, and optimized machine design for our customers.
Key Features & Technical Advantages:
- Precision Customization: The bore diameter and bolt pattern (PCD, number, and size of holes) are manufactured to your precise specifications, guaranteeing a perfect fit.
- Optimized Load Distribution: The single row of balls is precision-ground and arranged to handle combined loads (axial, radial, and moment) efficiently, providing stable and smooth rotation.
- Robust Construction: Manufactured from high-quality, through-hardened bearing steel, the rings offer high strength and resistance to deformation under load.
- Integrated Sealing Solutions: Multiple sealing options, such as rubber or labyrinth seals, are available to protect the ball raceway from contaminants like dust, water, and debris, significantly extending service life in harsh environments.
- Optional Gearing: Internal or external gear teeth can be integrated into the bearing's outer or inner ring, simplifying drive system design by eliminating the need for separate gear components.
- Pre-Lubrication & Maintenance: Bearings are pre-filled with high-quality grease suitable for a wide temperature range and can be designed with lubrication ports for easy re-greasing during maintenance.
Technical Specifications Overview:

Customer Benefits & Application Scenarios:
- Design Freedom & Integration: By specifying the exact bore and bolt pattern, engineers can design more compact and efficient machinery, reducing overall weight and complexity.
- Reduced Total Cost of Ownership: The direct mounting capability lowers assembly costs. The bearing's durability and effective sealing minimize downtime and maintenance expenses.
- Enhanced Reliability: Precision manufacturing and quality materials ensure consistent performance, critical for applications where failure is not an option.
- Versatile Industry Application: This bearing is ideal for a wide range of machinery, including but not limited to:
- Renewable Energy: Wind turbine yaw and pitch systems.
- Material Handling: Slewing rings for cranes, excavators, and robotic arms.
- Industrial Machinery: Turntables for welding positioners, indexing tables, and radar platforms.
- Construction Equipment: Central joints for aerial work platforms and compact cranes.

Frequently Asked Questions (FAQ):
-
Q: What information do you need from me to provide a quotation for a custom slewing bearing?
A: To provide an accurate quote and technical proposal, we typically require your desired bore diameter, the detailed bolt hole circle pattern (PCD, number, size, and thread specification), estimated load capacities (axial, radial, moment), rotational speed, and the intended application/environment. -
Q: Can you manufacture bearings with non-standard or very large bore diameters?
A: Yes, customization is our specialty. Our manufacturing capabilities allow us to produce bearings with bore diameters significantly outside standard ranges, including very large sizes. We will assess the feasibility based on your specific dimensions and load requirements. -
Q: What is the lead time for a custom-configured bearing like this?
A: Lead time varies depending on the complexity, size, and current production schedule. Typically, for standard material and medium complexity, lead times range from 8 to 12 weeks. We provide a confirmed timeline upon order confirmation. -
Q: Do you provide technical drawings or 3D models for approval before manufacturing?
A: Absolutely. We generate and provide detailed 2D engineering drawings (PDF/DWG) for your review and approval prior to commencing production. 3D models (STEP/IGES) can also be supplied upon request to facilitate your design integration. -
Q: How does the optional gearing work, and how do I choose between internal or external gears?
A: The gear is machined directly onto the bearing ring. The choice between internal (teeth on the inner bore) or external (teeth on the outer circumference) depends on your drive system layout, space constraints, and desired gear ratio. Our engineers can advise on the best option for your mechanism. -
Q: What are the recommended maintenance procedures for these bearings?
A: Our bearings are pre-lubricated for long life. We recommend periodic inspection of seals and re-lubrication through the provided grease nipples based on the operational hours and environmental conditions. The specific maintenance interval will be detailed in the product documentation. -
Q: Are your bearings suitable for outdoor or corrosive environments?
A: The standard material offers good resistance. For highly corrosive environments (e.g., offshore, chemical exposure), we can discuss optional surface treatments like zinc plating, painting, or using alternative materials like stainless steel for certain components. -
Q: What packaging do you use to ensure the bearing arrives undamaged?
A: We use robust, export-standard packaging. The bearing is typically coated with anti-rust oil, wrapped in waterproof material, placed in a custom wooden crate with internal bracing to prevent movement, and clearly marked with handling instructions.
