SS 61809-ZZ RICH 45x58x7

SS 61809-ZZ RICH Single Row Deep Groove Ball Bearing, Stainless Steel – 45 x 58 x 7 mm – Super Thin Section, Corrosion Resistant with Double Shields

Engineered for precise and reliable operation in applications where space is extremely limited and corrosion resistance is critical. The SS 61809-ZZ RICH single row deep groove ball bearing is expertly crafted from high-quality stainless steel, providing exceptional resistance to rust and corrosive elements. With precise dimensions of 45 mm inner diameter, 58 mm outer diameter, and an incredibly thin 7 mm width, this bearing is part of the "thin section" series, designed for compact assemblies and minimal weight.

This RICH bearing features double-sided non-contact shields (ZZ designation), which effectively protect the internal steel cage (guided by the rolling elements) and precision components from ingress of contaminants like dust and fine particles, while ensuring extremely low rotational friction. Manufactured with CN (normal) clearance, it guarantees consistent and smooth operation under standard loads, making it ideal for high-precision, miniature, and sensitive mechanisms.

Manufactured in China by RICH, this remarkably lightweight stainless steel deep groove ball bearing weighs a mere 0.004 kg. Its attributes of extreme compactness, superior corrosion resistance, and efficient sealing make it an excellent choice for robotics, drones, compact medical devices, precise instrumentation, and any other application where miniaturization, hygiene, and long-term reliability are paramount.
