The SW 685 ZZ is a high-precision, deep groove miniature ball bearing designed for applications requiring high rotational speed and low friction in confined spaces. Belonging to the extra-thin 6800 series, this specific bearing features a 5mm bore (d), an 11mm outer diameter (D), and a 3mm width (B). The 'ZZ' designation confirms the presence of two non-contact metal shields, permanently fixed to protect the internal raceways and rolling elements from dust and debris while maintaining essential lubricant integrity. Manufactured with high-grade 52100 chrome steel, the SW 685 ZZ ensures superior durability and dimensional accuracy necessary for sensitive equipment.
Optimized for reliability, this SW miniature bearing is ideal for use in medical diagnostic instruments, high-speed rotary encoders, small electric motors, RC hobby equipment, and specialized automation machinery where weight and space constraints are critical. Its deep groove geometry supports both radial and light axial loads, offering versatile performance. Choosing the SW 685 ZZ guarantees consistent performance, reduced maintenance cycles, and exceptional operational smoothness, reflecting SW’s commitment to industrial-grade precision even in the smallest component lines.
