As a professional manufacturer based in Luoyang, Henan, China, Henan San Kuang Machinery Technology Co., Ltd. specializes in the production of high-precision slewing bearings. Our Slewing Bearing with 4.5kNm Static Load Capacity, Zero Clearance, and P5 Precision Grade is engineered to deliver reliable performance in demanding applications. With a factory spanning 10,000-30,000 square meters and a dedicated team of 51-100 employees, we ensure rigorous quality control and consistent product excellence. This bearing is designed for applications requiring minimal backlash and high rotational accuracy, making it ideal for robotics, construction equipment, and wind turbines.
Product Features & Technical Specifications
- Zero Clearance Design: Eliminates internal play, providing stable positioning and precise rotation under load. This is critical for applications like indexing tables and antenna positioning systems.
- P5 Precision Grade: Meets high-accuracy tolerance standards, ensuring smooth operation and reduced vibration. The P5 grade offers a balance between precision and cost-effectiveness.
- 4.5kNm Static Load Capacity: Capable of handling moderate axial, radial, and moment loads without permanent deformation. Suitable for medium-duty machinery.
- Durable Material: Manufactured from high-quality bearing steel (e.g., GCr15), heat-treated for hardness and wear resistance.
- Customizable Dimensions: Outer diameter, inner diameter, and mounting hole patterns can be tailored to specific customer requirements. Please consult our engineers for details.
- Sealing Options: Available with rubber seals or metal shields to protect against dust and moisture, extending service life.

Frequently Asked Questions (FAQ)
-
Q: What does 'zero clearance' mean in this slewing bearing?
A: Zero clearance indicates that the bearing is preloaded to eliminate any internal play between the rolling elements and raceways. This ensures high rigidity and precise rotational positioning, ideal for applications where backlash is unacceptable. -
Q: Is P5 grade suitable for high-speed applications?
A: P5 grade is moderate precision. While it can handle moderate speeds, for very high-speed applications, a higher grade like P4 may be recommended. Please consult our engineering team for specific speed requirements. -
Q: Can this bearing support axial loads in addition to moment loads?
A: Yes, the 4.5 kNm static load capacity refers to the moment load. The bearing can also support axial and radial loads, but the combined load should be within the rated values. Contact us for load rating charts. -
Q: What is the typical lead time for custom sizes?
A: Lead time depends on complexity and quantity. Standard sizes may ship within 15-20 days; custom orders typically require 30-45 days. We can expedite for urgent projects upon request. -
Q: Do you provide mounting hardware or installation instructions?
A: We provide detailed installation manuals and recommended bolt torque values. Mounting bolts are available as optional accessories. Please specify when ordering. -
Q: How do you ensure the quality of each bearing?
A: Every bearing undergoes dimensional inspection, hardness testing, and rotational accuracy checks. Our quality management system is certified to ISO9001, and we also perform random load tests to verify performance. -
Q: Can you supply bearings with special coatings or seals?
A: Yes, we offer options such as polyurethane seals, Viton seals, and anti-corrosion coatings (e.g., zinc plating, black oxide). Custom requirements are welcome. -
Q: What is the warranty period for this slewing bearing?
A: We offer a standard 12-month warranty against manufacturing defects. Extended warranty options are available based on contract terms.
