SKF 61818-2RS Deep Groove Ball Bearing, 90x115x13mm, Sealed, High Precision Thin Section
The SKF 61818-2RS is a high-performance deep groove ball bearing engineered for applications requiring minimal cross-section and reduced weight. This single-row bearing belongs to the 618 series (ISO 18), characterized by its extra-thin section profile (90 mm bore, 115 mm outer diameter, and 13 mm width). Manufactured using SKF's premium-grade, ultra-clean steel, the bearing provides superior fatigue life and exceptional running accuracy. The '-2RS' designation confirms that the bearing is fitted with two low-friction contact seals made of NBR (Nitrile Butadiene Rubber), ensuring reliable retention of the factory-applied, high-quality grease and robust protection against industrial contaminants, moisture, and dust ingress. This design maximizes uptime and reduces maintenance demands in demanding environments.
Optimized for compact designs such as precision gearboxes, robotics, electric motors, and specialized pumps, the 61818-2RS delivers the renowned operational reliability expected from SKF. Despite its thin profile, this bearing maintains a competitive balance of radial and moderate axial load capacity. Its compact form factor contributes to energy efficiency and allows designers to minimize housing size and weight without compromising performance. Selecting this SKF solution guarantees reduced total cost of ownership through extended service life and reliable operation even at higher limiting speeds, making it the definitive choice for critical machinery requiring world-class precision.
