As a leading manufacturer of slewing bearings with over a decade of expertise, Henan San Kuang Machinery Technology Co., Ltd. specializes in delivering high-performance, reliable rotation solutions for heavy-duty industrial applications. Our Single Row Ball Slewing Bearing in Standard Sizes is engineered to provide exceptional load capacity, smooth operation, and long service life, making it an ideal choice for turntables, cranes, and various machinery requiring robust rotational support. With our extensive manufacturing capabilities across a 10,000-30,000 square meter facility and a commitment to stringent quality control certified by ISO 9001 among other standards, we ensure every bearing meets the precise demands of global markets.
This bearing is designed to handle combined loads—axial, radial, and moment loads—simultaneously, thanks to its optimized raceway geometry and high-quality steel construction.
- Superior Load Capacity & Durability: Manufactured from high-carbon chromium bearing steel (like GCR15), the bearing undergoes precise heat treatment to achieve a surface hardness of HRC 58-62 on raceways, ensuring exceptional resistance to wear, deformation, and fatigue. This translates to a longer operational lifespan even under continuous, high-stress conditions.
- Precision Engineering for Smooth Operation: The single row of balls, arranged in a four-point contact design, minimizes friction and ensures smooth, precise rotation with low starting torque. This is crucial for applications requiring accurate positioning and seamless motion control.
- Versatile Standard Sizing & Easy Integration: Offered in a range of standard dimensions, these bearings facilitate easier design-in and replacement. They come with pre-drilled mounting holes (bolt-through type) for straightforward installation onto your machinery's structure.
- Robust Sealing & Protection: To protect the critical rolling elements and raceways from contaminants like dust, moisture, and debris, the bearing can be equipped with high-performance sealing options (rubber or metal seals). This is vital for maintaining performance in harsh outdoor or industrial environments.
- Comprehensive Customization: While standard sizes offer convenience, we understand that every project is unique. Our engineering team can customize bearings with specific internal or external gear teeth, special hole patterns, alternative materials, or different sealing solutions to perfectly match your application's requirements.
The following table outlines typical specifications for our standard series single row ball slewing bearings. Please note that specific values depend on the exact size selected.

Frequently Asked Questions (FAQ)
Q1: What is the primary advantage of a single row design compared to a double row ball slewing bearing?
A: The single row ball slewing bearing offers a more compact cross-section and can be a cost-effective solution for applications where high moment load capacity is required but space constraints exist. It provides excellent load handling in a simpler, often more economical design.
Q2: Are these "standard size" bearings truly off-the-shelf, or is there a lead time?
A: While we maintain inventory for certain common standard sizes, most bearings are produced to order to ensure optimal specification matching. Typical production lead times range from 4-8 weeks, depending on size, complexity, and current order volume. We can provide accurate timelines upon inquiry.
Q3: Can this bearing operate in outdoor or corrosive environments?
A: Yes, but proper protection is key. The standard bearing is made of steel and requires protection against corrosion. We offer options such as surface treatments (e.g., zinc plating, phosphating) or the use of stainless steel components (available upon request) for enhanced corrosion resistance. Effective sealing is also critical for outdoor use.
Q4: How do I determine the correct size and load rating needed for my application?
A: Selecting the right bearing requires calculating the maximum axial force, radial force, and overturning moment your application will generate, along with considering the required service life and safety factors. Our technical team can assist you with this calculation if you provide the basic operational parameters and conditions.
Q5: Is lubrication required, and how is it performed?
A: Yes, lubrication is essential for long life and smooth operation. The bearing comes pre-greased from the factory. It is equipped with standard grease fittings (zerk fittings) for periodic re-lubrication. The recommended grease type and re-lubrication interval depend on the operating speed, load, and environment.
Q6: What mounting precautions should be taken during installation?
A: Proper installation is crucial. Key points include: ensuring the mounting surfaces are flat, clean, and sufficiently rigid; using high-strength bolts tightened to the specified torque in a cross-pattern sequence; avoiding any impact or shock loads directly on the bearing rings; and checking the gear mesh (if applicable) for proper backlash after mounting.
Q7: Do you provide installation and maintenance documentation?
A: Absolutely. With each bearing shipment, we provide comprehensive documentation that includes detailed installation instructions, recommended maintenance procedures, lubrication guidelines, and a technical data sheet with specifications.
Q8: What is your policy on customizing the bearing with gear teeth or special bolt holes?
A: Customization is one of our strengths. We regularly produce bearings with internal or external spur gears machined into the rings. Special hole patterns, additional tapped holes, or different sealing arrangements are also common requests. Please share your detailed drawings or requirements for a customized quotation.
