The R144-ZZ is a Double Metal Shielded Miniature Deep Groove Ball Bearing engineered for high-speed precision equipment where low friction and reliable operation are essential. Fitted with two non-contact metal shields (ZZ) on both sides, it provides effective protection against dust and larger particles while maintaining minimal torque and allowing high rotational speeds. With a 3.175 mm bore and ultra-compact cross-section, this bearing is ideal for small motors, instrumentation, robotics, and miniature drives operating in clean environments.
