Engineered for micro-mechanics and assemblies with extreme space constraints, the 692-ZZ is an ultra-miniature single-row deep groove ball bearing. Featuring a microscopic 2 mm bore, a 6 mm outer diameter, and a 3 mm width, this precision component is designed to facilitate smooth rotational movement in the most compact devices. Fitted with double steel shields (ZZ), the bearing securely retains its internal lubrication while blocking microscopic dust and contaminants. Manufactured from premium-grade chrome steel, the 692-ZZ offers an exceptional balance of wear resistance, extremely low friction torque, and extended operational longevity for intricate mechanical systems.
