The R144ZZ RICH is a high-precision miniature deep groove ball bearing, specifically engineered for extremely compact and sensitive rotational applications. Manufactured by RICH, this bearing features ultra-precise metric dimensions of 3.175 x 6.35 x 2.779 mm.
Its miniature size, combined with the deep groove raceway design, ensures low-friction running while still providing efficient support for moderate radial and minor axial loads. The R144ZZ RICH is built with a durable steel cage that promotes optimal ball spacing and stable rotation. Its shielded design helps retain the internal lubrication and protects the internal components from large contaminants. This bearing is a perfect component for robotics, small electric motors, medical devices, and precision instruments where reliability in a minimal space is required.
