Description

Stainless steel deep groove ball bearings are a type of bearing designed for applications where corrosion resistance and hygiene are essential. They are constructed using stainless steel for both the inner and outer rings, as well as the balls and often the cage.

Here's a brief description of their features and applications:

Corrosion Resistance: Stainless steel bearings are highly resistant to corrosion from moisture, chemicals, and other environmental factors. This makes them ideal for use in industries such as food and beverage, medical equipment, marine, and outdoor applications where exposure to harsh conditions is common.

Hygiene: Stainless steel is non-reactive and easy to clean, making these bearings suitable for applications requiring strict hygiene standards, such as food processing and pharmaceutical manufacturing.

High Temperature Resistance: Stainless steel bearings can withstand higher temperatures compared to standard bearings, making them suitable for applications where heat resistance is required.

Low Maintenance: Due to their corrosion resistance, stainless steel bearings require minimal maintenance, resulting in reduced downtime and lower overall operating costs.

Versatility: Stainless steel deep groove ball bearings are available in various sizes and configurations, allowing them to be used in a wide range of applications, including pumps, motors, conveyors, and agricultural equipment.

QIBR - W 61803 2Z Deep Groove Ball Bearing Quality Control

Dimension measurement: Multiple high-precision instruments are used to measure various dimensions of the bearing, with an accuracy of up to 0.001mm.

Rotation accuracy: A dial gauge measures minor surface flaws or deviations, with measurement accuracy reaching 0.001mm.

Hardness measurement: The surface hardness of the bearing is measured using a hardness tester, with an accuracy of ±0.5HRC.

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

Geometric tolerance: A profilometer is used to measure the geometric shape and relative position of the bearing.

Noise monitoring: A vibration meter monitors vibrations during operation, providing noise data with a noise vibration level not lower than Z3V3.

Raw material control: Steel and parts are sourced from ISO 14001-certified suppliers, ensuring product stability while promoting sustainable development.
