The 6818-2RS is a thin-section deep groove ball bearing engineered for applications where space constraints and high radial load capacity must coexist. Featuring dual contact rubber seals (2RS), this bearing provides superior exclusion of moisture, fine dust, and contaminants, making it the preferred choice for environments demanding absolute lubricant retention. With a 90mm bore, 115mm outer diameter, and 13mm width, it is a critical component for heavy-duty industrial gearboxes, precision rotary tables, and large-format electric motors requiring stable operation under consistent loads.
