QIBR - SI-51 Universal Ball Bearing Characteristics

SI-51 Universal Ball Bearing, long service life, low production cost, high cost performance. SI-51 Universal Ball Bearing, can bear radial load and a little axial load at the same time, suitable for low-cost mechanical equipment.

SI-51 Universal Ball Bearing Product Features and Advantages

Multi-Degree-of-Freedom Movement: The ball supports motion in various directions, allowing for free rotation across multiple axes.

High Precision and Stability: Spherical contact provides gap-free motion, enhancing transmission precision and stability.

Strong Angle Adjustment Capability: The bearing can handle significant angular deviations and can be adjusted as needed, making it adaptable to various working environments.

Low Vibration and Noise: The spherical contact surface reduces friction during movement, lowering operational noise and effectively cushioning against impacts and vibrations.

Application: Widely used in automotive, agricultural equipment, transmission systems, feeding systems, processing systems, mechanical manufacturing, and packaging machinery auxiliary equipment.

QIBR - SI-51 Universal Ball Bearing Optimization

Process Optimization:High-precision machining processes ensure the fit between the ball and the race, improving motion smoothness.

Housing Material: The housing material can be selected based on bearing operational requirements, such as zinc-plated carbon steel, stainless steel, reinforced nylon, etc.

Ball Material: The ball material can be chosen according to the bearing's working environment or customer requirements, such as carbon steel balls, zinc-plated carbon steel balls, bearing steel balls, etc.

Further Customization: QIBR can design and optimize bearings according to customer drawings and operational requirements.

QIBR - SI-51 Universal Ball Bearing Quality Control

Dimension measurement: Various professional high-precision instruments are used to measure the bearing’s dimensions, 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.

Axial Clearance: Special tools for measuring the axial clearance of universal bearings are used to determine the clearance.

Noise monitoring: A vibration meter monitors vibrations during operation, providing noise data.

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