QIBR - 36 0411 01 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 - 36 0411 01 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.

The outer ring has excellent mechanical performance, with high strength and toughness. After quenching and tempering (Q+T), it exhibits fatigue resistance, impact resistance, and excellent low-temperature impact toughness.
The inner ring has excellent mechanical performance, with high strength and toughness. After quenching and tempering (Q+T), it exhibits fatigue resistance, impact resistance, and excellent low-temperature impact toughness.
Rollers and balls are both types of rolling elements, which are the most crucial components of rotary support bearings and the most commonly used rolling elements in the bearing industry.
It is located between the outer raceway, inner raceway, and rollers/balls of the bearing. It is a isolator block that serves as a cage.
Its role serves two purposes: Firstly, to prevent the loss of lubricating grease or oil inside the bearing, ensuring proper lubrication. Secondly, to shield the bearing from external dust or harmful gases, thus preventing damage.
To ensure the smooth operation of the bearing, it is necessary to inject lubricating grease or oil between the inner and outer rings of the bearing. The function of lubricating grease or oil is to reduce friction coefficient and wear, minimize bearing heat and friction losses, and enhance bearing lifespan.
