The SW 689-2RS bearing is engineered specifically for applications requiring high rotational accuracy within limited spatial envelopes. As a member of the extra-thin 6800 series, this deep groove ball bearing features a compact 9mm bore, 17mm outer diameter, and a narrow 4mm width, minimizing both weight and profile. Utilizing high-grade, vacuum-degassed chrome steel (AISI 52100 equivalent), the internal geometry is optimized for moderate radial loads and low-to-medium axial loads, ensuring stable performance across a variety of operating conditions. The critical -2RS sealing configuration provides robust protection against industrial dust, moisture, and fine contaminants, retaining the internal high-performance lithium grease for significantly extended service intervals and reduced maintenance burdens.
Designed for precision instrumentation, robotics, specialized electric motors, and sensitive optical equipment, the SW 689-2RS delivers reliable, low-torque operation. Its precision manufacturing, typically conforming to P6 (ABEC-3) tolerance standards, guarantees minimal friction and noise levels, crucial for sensitive applications. Integrating this bearing results in immediate operational improvements by combining durability, contamination resistance, and the space-saving benefits of a thin-section design. Choose the SW 689-2RS for superior reliability and optimized system design in demanding micro-mechanical environments.
