SKF 628/5 ZZ - Miniature Deep Groove Ball Bearing 5x11x4 mm

The SKF 628/5 ZZ is a precision-engineered miniature deep groove ball bearing, measuring 5 mm inner diameter x 11 mm outer diameter x 4 mm width, and equipped with double metal shields (ZZ) to protect against dust and debris while retaining lubricant. Designed for high-speed performance—up to 60,000 rpm—this compact bearing ensures low friction, smooth operation, and long-lasting reliability.

Built with a durable steel cage and hardened bearing components, it withstands radial and axial loads typical in miniature applications. Its tight tolerances and sealed design make it perfect for electric motors, small appliances, RC vehicles, drones, precision instruments, and other compact mechanical systems.
