Product structure:

This bearing features a deep groove ball design with a bore diameter of 4mm, outer diameter of 10mm, and width of 4mm. It includes double-sided metal shields (denoted by ZZ), is made of carbon or chrome steel, and typically uses a stamped steel or engineered plastic cage, offering a compact structure and effective sealing.

Key performance features:

It offers high-speed operation, low friction, and low noise. The shields effectively prevent contamination, extending service life. With moderate load capacity, easy installation, and cost-effectiveness, it is ideal for light to medium-duty applications.

Main application scenarios:

Common applications include small motor rotors, fan blades, encoders, printer rollers, instrument pointers, toy gearboxes, and precision transmission components, where it provides reliable rotational support.

Technical Specifications & Requirements:

It complies with ISO 15:2011 standards, typically with CN grade (normal group) radial clearance. The recommended operating temperature range is -20°C to +120°C. Proper lubrication (pre-filled grease) must be maintained, and overload or shock loads should be avoided. Installation requires matching shaft and housing tolerances.
