QIBR - 4.459 Combined Bearing Optimization

High-Performance Materials: Bearing materials can be selected based on operating conditions and customer requirements, including alloy steel, ceramics, and combinations of ceramic balls with steel raceways.

Grease Selection: Grease can be chosen according to customer needs, such as NSK LGHP 2 or Mobilith SHC 220.

Coating Options: Suitable coatings can be selected based on customer requirements and working environments, such as PTFE for anti-friction, chrome for wear resistance, and zinc-nickel alloy for corrosion resistance.

Diverse Types: Combined Bearings can be selected based on customer needs and suitability, such as needle bearings without inner rings combined with thrust ball bearings, or those with covers.

More customization: QIBR can design and optimize bearing combinations and materials based on customer drawings and operating conditions.

QIBR - 4.459 Combined Bearings quality control

Dimension measurement: Various high-precision instruments are used to measure multiple dimensions of the bearings, achieving a maximum precision of 0.001mm

Rotation accuracy: A dial gauge is used to measure small surface defects or deviations, with a measurement precision of 0.001mm.

Hardness measurement: Hardness is measured using a hardness tester, with a precision of ±0.5HRC.

Metallographic analysis: Professional metallographic microscopes are used to analyze the internal metallographic structure of metals.

Geometric Tolerance: A profile projector is used to measure the geometric shape and relative position of the bearings.

Noise monitoring: Vibration meters monitor the vibration during operation to obtain noise data.

Raw material control: Steel and parts are purchased from suppliers certified by ISO 14001 to ensure product stability and promote sustainable development.
