Product Description

The 8x14x4 micro bearings are ultra-compact Slim ball bearings designed for miniature motor applications, featuring precise dimensions (8mm inner, 14mm outer diameter, 4mm width) to optimize space in compact electromechanical systems. These miniature motor bearings typically operate within 5-24V DC systems, supporting direct integration with micromotors and encoders without additional interfaces. Engineered for -30°C to +120°C environments, they excel in robotics, medical devices, and precision instruments. Constructed with chrome steel rings and nylon cages, they offer low-noise rotation up to 15,000 RPM while maintaining minimal friction. Their slim profile enables close-proximity installations in multi-module assemblies, though their reduced size slightly limits radial load capacity compared to standard bearings. Special lubrication ensures compatibility with high-speed operations in contamination-sensitive applications.
