Description
The design feature of this bearing is its ability to handle radial, axial, and moment loads simultaneously, thanks to its intersecting cylindrical rollers arranged at a 90 degree angle.
07 0770 00 Slewing Bearing Features and Advantages
Compact design: Compact structure, it can be installed in space-constrained environments, and has a wider range of applications.
High load capacity: It can withstand axial, radial and overturning moments at the same time, suitable for heavy-duty applications.
Superior precision: Maintain high precision during use and reduce errors in equipment operation.
High temperature and wear resistance: Made of high-temperature bearing steel, with good wear resistance and strength.
Application: Widely used in lifting machinery, engineering machinery, transportation machinery, mining machinery, metallurgical machinery, medical equipment, ships, warships, radar, wind power generation and other fields.
QIBR - 07 0770 00 Slewing Bearing Optimization
Grease replacement: Replace grease with other greases such as SFK, Mobil, Krupp, etc. to optimize the working performance and use conditions of the bearing.
Coating optimization: Provide other coatings such as zinc plating or nickel plating to enhance corrosion resistance and wear resistance and extend its service life in harsh environments.
Process optimization: Optimize the bearing production process, increase the bearing operating temperature range, and improve the bearing accuracy and stability.
More customization: QIBR can optimize the bearing structure design according to customers’ drawings or equipment requirements to meet equipment needs.
QIBR - 07 0770 00 Slewing support bearing quality control
Dimension measurement: Use a variety of professional high-precision instruments to measure multiple dimensions of the bearing, with the highest accuracy up to 0.01mm.
Rotation accuracy: Use a dial indicator to measure small flaws or deviations on the bearing surface, with a measurement accuracy of up to 0.01mm.
Hardness measurement: Use a Leeb hardness tester to measure the bearing surface hardness, with a measurement accuracy of ±6HLD.
Metallographic analysis: Use a professional metallographic microscope to analyze the internal metallographic structure of the metal.
Geometric tolerance: Use a roundness meter to measure the bearing geometry and relative position.
Noise monitoring: Use a vibration meter to monitor the vibration during operation and obtain noise data.
