The SW 623-2RS is a premium miniature deep groove ball bearing engineered for applications requiring high precision and reliability within confined spaces. Featuring a 3mm bore, 10mm outer diameter, and 4mm width, this bearing operates under the rigorous ISO 623 standard. The robust internal geometry ensures low-friction rotation and stable performance, accommodating both radial and moderate axial loads. The -2RS designation confirms the presence of contact rubber seals on both sides, providing superior retention of the high-quality grease fill while effectively blocking contaminants like dust and moisture, significantly extending service life in demanding environments. Manufactured to standard P0 (ABEC 1) or better precision grade, the SW 623-2RS is the professional choice for reliability.
Ideal for use in robotics, hobby motors, high-speed dental tools, instrumentation, and small electronic assemblies, the 623-2RS delivers maintenance-free operation straight out of the package. The double-sealed configuration eliminates the need for periodic relubrication, drastically reducing downtime and lowering total cost of ownership. The SW brand guarantees consistent quality control and material integrity, utilizing high-grade bearing steel (e.g., SAE 52100) for races and balls, ensuring maximum fatigue life and sustained performance under continuous operational cycles. Choose the SW 623-2RS for high-speed capability and outstanding durability in your miniature designs.
