Description
The NTN 608ZZ is a single‑row deep‑groove ball bearing engineered for high‑speed rotation and reliable radial‑load support in compact mechanical assemblies. It features double metal shields (ZZ) that retain lubricant while keeping out dust and debris, making it suitable for electric motors, fans, gearboxes, small machinery, and skateboard/inline‑skate wheels. The bearing uses steel balls, a steel cage, and precision‑ground raceways to minimize friction, vibration, and noise—attributes highlighted in the NTN 608ZZC3/EM listing, which notes deep‑groove geometry for high‑speed performance and a steel cage for smooth ball spacing . With an 8 mm bore, 22 mm outer diameter, and 7 mm width (standard 608 dimensions), the 608ZZ provides a compact, durable, and widely interchangeable solution across industrial and consumer applications.
