SS638/2 2Z RICH Single Row Deep Groove Ball Bearing, Miniature, Stainless Steel – 2 x 5 x 2.3 mm – Precision for Tiny, Corrosive Applications

Engineered for micro-precision in challenging environments. The SS638/2 2Z RICH miniature single row deep groove ball bearing, meticulously crafted from stainless steel, is designed for incredibly small-scale applications demanding both exceptional corrosion resistance and precise rotational accuracy. With ultra-compact dimensions of 2 mm inner diameter, 5 mm outer diameter, and a slim 2.3 mm width, it provides critical support where minimal footprint is essential.

This RICH bearing features a durable steel cage for consistent performance and double-sided non-contact shields (2Z, also known as ZZ). These shields deliver robust protection against dust, dirt, and external contaminants while ensuring consistently low friction, making it ideal for sensitive mechanisms.

Manufactured in China by RICH, this stainless steel miniature deep groove ball bearing weighs a mere 0.001 kg, demonstrating its extraordinary lightness combined with remarkable durability. Its design is perfectly suited for applications such as miniature robotics, small instrumentation, delicate medical devices, and intricate optical equipment that operate in conditions prone to moisture, humidity, or aggressive chemical agents.
