At Henan San Kuang Machinery Technology Co., Ltd., we are committed to delivering high-precision slewing bearings that meet the rigorous demands of heavy machinery and industrial applications. Our Factory Tested Slewing Bearing with Mill Test Report features an outer diameter of 0.5 meters and comes with a comprehensive 1-year warranty, ensuring reliable performance and long service life. Manufactured in our 10,000–30,000 square meter facility in Luoyang, China, each bearing undergoes strict factory testing and is accompanied by a Mill Test Report to verify material traceability and quality standards.
This slewing bearing is designed for applications requiring smooth rotation under heavy loads, such as cranes, excavators, and wind turbines. With a compact yet robust construction, it offers excellent load-bearing capacity, low friction, and high rotational accuracy. The 0.5m outer diameter makes it suitable for medium-sized equipment, and our flexible customization options allow for gear configurations, sealing types, and material choices to match your specific needs.

Frequently Asked Questions (FAQ)
-
Q: What is a Mill Test Report and why is it important?
A: A Mill Test Report (MTR) is a quality document that certifies the chemical and mechanical properties of the raw materials used in the bearing. It ensures traceability and compliance with industry standards, giving you peace of mind about the product's durability. -
Q: Can the slewing bearing be used in outdoor environments?
A: Yes, it comes with a double lip seal that protects against dust, water, and UV exposure. For harsh environments, we can also provide additional corrosion protection (e.g., galvanized coating) upon request. -
Q: How do I choose between internal gear, external gear, or no gear?
A: It depends on your drive system design. Internal gears are often used in compact assemblies, while external gears are easier to couple with pinions. Contact our technical team for guidance based on your specific application. -
Q: What is the typical lead time for this product?
A: Standard sizes (0.5m OD) with common configurations can be shipped within 15–20 working days. Custom orders may require 25–30 days. We can expedite based on order volume. -
Q: Does the warranty cover bearing failure due to improper installation?
A: The 1-year warranty covers manufacturing defects. For installation-related issues, we provide detailed installation manuals and technical support to minimize risks. Training can also be arranged. -
Q: Are there any certifications that apply to this product?
A: Our factory holds multiple certifications including ISO9001, ISO14000, OHSAS18001, and others. The bearing itself is manufactured under these quality management systems. Specific product certifications (e.g., CE) can be provided upon request for certain markets. -
Q: Can I request a sample before placing a bulk order?
A: Yes, we offer sample orders for evaluation. The sample price includes the Mill Test Report and is refundable upon bulk order placement. Please contact our sales team for details. -
Q: What is the maximum load capacity for the 0.5m OD slewing bearing?
A: The exact capacity depends on the design (gear type, material, and raceway hardening). Typical static axial load capacity is up to 800 kN, but we recommend providing your load parameters for a customized calculation.
