The double contact rubber seals (2RS) provide effective exclusion of moisture, dust, and fine contaminants, making it well suited for equipment operating in moderate industrial environments where long service life and minimal maintenance are priorities. The 6819-2RS is a thin-section deep groove ball bearing engineered for applications requiring reliable sealing within a compact axial envelope. With a 95 mm bore and a slender 13 mm cross‑section, it delivers stable radial load capacity while minimizing housing width.
