The R188ZZ RICH is a precision miniature single row deep groove ball bearing, designed for reliable performance in compact and high-speed mechanical assemblies. Manufactured by RICH, this bearing features highly accurate metric dimensions of 6.35 x 12.7 x 4.762 mm.
Deep groove ball bearings are the most prevalent type due to their versatility in handling combined radial and light axial loads. The R188ZZ RICH is constructed with a durable pressed steel cage that ensures optimal ball separation and smooth running characteristics, suitable for elevated speeds and reduced friction requirements. Its miniature footprint and low weight (0.003 kg) make it an essential component for precision instruments, small electronic devices, and models where space and efficiency are paramount.
