SW 699-2RS Deep Groove Ball Bearing - Sealed (9x20x6mm) - Thin Section Series
The SW 699-2RS bearing is a high-precision, deep groove ball bearing from the extra-light 6900 series, specifically engineered for applications requiring minimal cross-section and reduced weight. Featuring a 9 mm bore, 20 mm outer diameter, and 6 mm width, this bearing is manufactured from high-quality 52100 chromium steel, ensuring long life and excellent resistance to fatigue. The -2RS designation confirms the presence of two contact rubber seals (Nitrile Butadiene Rubber - NBR), which effectively retain the factory-applied lithium grease and prevent the ingress of dust, moisture, and fine particulate contaminants, making it a reliable, maintenance-free solution for demanding environments.
Designed for moderate radial and axial loads, the 699-2RS offers superior rotational accuracy and reliability crucial for precision machinery, small gearboxes, electric motors, and instrumentation. Its thin-section geometry allows for streamlined designs where space and weight limitations are critical factors, without sacrificing operational integrity. Choosing the SW 699-2RS guarantees industrial-grade performance, minimizing downtime and optimizing the efficiency of automated systems and consumer electronics where reliable, compact rotation is essential.
