The SW 626-2RS is a premium deep groove ball bearing designed for applications demanding high reliability, excellent load capacity, and protection against contamination. Featuring a 6mm bore, 19mm outer diameter, and 6mm width, this bearing utilizes high-grade vacuum-degassed chrome steel (52100) for superior hardness and extended fatigue life. The key differentiator is the non-contact '2RS' closure system, which incorporates durable nitrile rubber seals on both sides, ensuring the internal high-performance lubricant is retained while effectively blocking dust, moisture, and debris. This design minimizes required maintenance and guarantees consistent performance across a wide range of operational temperatures and speeds.
Engineered to meet stringent ISO dimensional standards, the SW 626-2RS is ideal for critical rotating equipment such as small electric motors, high-speed gearboxes, industrial pumps, automation robotics, and precision instruments. Its optimized raceway geometry allows it to handle substantial radial loads as well as moderate axial loads in both directions. Selecting the SW product ensures maximum uptime and reduced overall total cost of ownership (TCO) by providing exceptional rotational accuracy and proven resistance to vibration and misalignment under demanding industrial cycles.
