QIBR - ROD02000-026DA15-900-000 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 - ROD02000-026DA15-900-000 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.
