61803-RS1 Bearing Structural Features & Performance Benefits
Compact Design & High Precision: With dimensions of 17×26×5 mm and ABEC 1 precision, this bearing offers optimal space utilization while maintaining running accuracy. The single row deep groove construction provides excellent radial load capacity (456 lbf dynamic, 286 lbf static) in minimal cross-section.
Enhanced Sealing Performance: The RS1 rubber contact seal effectively prevents contaminant ingress while retaining lubricant, making it suitable for applications where maintenance access is limited. This sealing solution maintains performance across a wide temperature range (-30° to 120°C).
Material Excellence: All critical components including rings, balls, and cage are manufactured from chrome steel, ensuring consistent hardness, wear resistance, and dimensional stability under load.
High-Speed Capability: With a limiting speed of 34,000 rpm, this bearing supports demanding rotational requirements while maintaining reliable operation.
