The SSMR74 RICH Single Row Deep Groove Ball Bearing (4 x 7 x 2 mm) is a micro-miniature stainless steel bearing with an extra-thin 2 mm width, ideal for high-speed, corrosion-resistant applications in micro-robotics and instruments.
The SSMR74 RICH is a micro-miniature Single Row Deep Groove Ball Bearing manufactured by RICH. This component is one of the smallest available, featuring extreme precision and compact dimensions of 4 mm bore, 7 mm outer diameter, and a remarkably thin 2 mm width.
Constructed from Stainless Steel, the SSMR74 RICH provides superior resistance to corrosion and moisture, making it essential for use in wet, humid, or specialized clean-room environments. Its deep groove raceway design and steel cage ensure reliable performance, supporting combined radial and axial loads while maintaining extremely low rotational friction. The ultra-thin 2 mm profile is crucial for designers maximizing rotational performance in the smallest possible footprint. The SSMR74 RICH is ideal for applications in micro-robotics, miniature encoders, dental tools, and high-sensitivity measuring equipment.
