Product: Slewing bearing
Outer diameter: 5300mm
Application: Tunnel boring machine
On July 1, a set of slewing bearing with an outer diameter of 5300mm was successfully delivered to Russia, which refreshed a record in exporting large diameter slewing bearings to Eastern Europe and Central Asia. This slewing bearing features 7 grades of gear accuracy and 5300mm outer diameter, which was specially designed and manufactured for use in the tunnel boring machines with 10m in diameter.
Russia is the largest country in the world spanning two continents of Europe and Asia. The total amount of infrastructure construction projects is large, so the demand for construction machinery and equipment is huge. In the early stage of the project, the customer visited our factory and discussed with us about the technical agreement many times. After around 100 days of manufacturing, the slewing bearing was finally delivered to the customer on time.
With 10 years of experience in the R&D of large diameter slewing bearings, LYJW has been leading the industry of large diameter slewing bearings. We have extensive experience in design, R&D, manufacture, and inspection of slewing bearings. Therefore, LYJW is confident to provide qualified heavy duty bearings for high demanding applications.
After rough turning, the workpiece is detected by an ultrasonic flaw detector to examine cracks or other flaws and ensure the bearing’s stable quality and normal service life. Quenching and tempering can be conducted according to the requirements, to improve the strength and fatigue resistance of the material.
To ensure consistent quality control, we have applied a series of specific and strict measures across all areas of our company. As a high-tech enterprise, our products have passed ISO9001-2000 quality system certification, CCS, ABS, BV, GL and other certifications, and have obtained a number of patent certificates.
We offer both standard and custom bearings tailored to our customers’ specific requirements. After a thorough examination of the bearing condition, size, bearing tooth parameters and any other special processes prescribed by the customer, we will then recommend the most suitable model. To ensure the customer's satisfaction, we also provide detailed diagrams, three-dimensional drawings, and load curves to confirm.
