High-Performance Materials: Bearing materials are replaced based on different working conditions, such as GCr15, 100Cr6, and bearing steel.

Surface Heat Treatment: Heat treatments, such as nitriding and carburizing, are used to enhance the surface hardness and wear resistance of the bearings.

Surface Coatings: Surface coatings are applied according to customer requirements, such as chrome plating, nickel plating, or PTFE coatings.

More customization: QIBR can design and optimize bearings based on customer drawings and operational requirements.

QIBR - RNA2207-2RSR Cam Followers quality control

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

Rotation accuracy: A micrometer is used to measure small defects or deviations on the bearing surface, achieving measurement precision of 0.001mm.

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

Metallographic analysis: A professional metallographic microscope is used to analyze the internal metallographic structure of the metal.

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.
