Product Description

The 3x8x4 Precision Ball Bearings are compact, high-performance components engineered for applications requiring minimal friction and exceptional radial load capacity. With dimensions of 3mm inner diameter, 8mm outer diameter, and 4mm width, these High Precision 3x8x4 Bearings operate within a temperature range of -30°C to +120°C, supporting rotational speeds up to 18,000 RPM. Designed for seamless integration into micro-mechanical systems, they feature shielded or open configurations for direct mounting in robotics, medical instruments, and precision optical devices. The 3x8x4 Precision Radial Bearings utilize chrome steel or ceramic hybrid materials, ensuring low noise operation and extended service life under continuous duty cycles. While offering superior axial stability and vibration resistance, their miniature size requires careful handling during installation. Typical industrial uses include CNC spindle assemblies, drone motors, and laboratory equipment demanding micron-level positional accuracy.
