699-2RS Sealed Deep Groove Ball Bearing for Precision Miniature Mechanisms | 9×20×6 Mm

The 699-2RS is a Double Rubber-Sealed Miniature Deep Groove Ball Bearing designed for compact, high-reliability applications where protection against moisture and fine contaminants is essential. With two rubber contact seals (2RS) on both sides, this bearing provides superior sealing performance, retaining lubrication and preventing ingress of dust, dirt, and fluids. Featuring a 9mm bore and an ultra-light cross-section, it is ideal for sensitive precision instruments, small motors, and devices operating in challenging environments where space is limited and cleanliness is critical.



699-2RS Deep Groove Ball Bearing 9×20×6 mm | ISO 69 Series – Extra Light | Double Rubber Sealed

This versatile deep groove bearing is designed for smooth and reliable operation at speeds up to 30,000 r/min (Oil). It handles moderate radial loads and accommodates light axial loads from either direction, making the 699-2RS an excellent sealed solution for small precision instruments, miniature drives, and mechanisms where protection against moisture and contaminants is essential for long-term performance.
