SW 8509 Precision Deep Groove Ball Bearing | 45x85x19mm | High-Speed Industrial Motor Rated
The SW 8509 Deep Groove Ball Bearing is engineered for high-reliability industrial applications, featuring a robust 2RS sealing configuration to ensure maximum contaminant exclusion and grease retention. Built from premium-grade, heat-stabilized bearing steel, the 8509 delivers superior dynamic load capacity (Cr: 32.5 kN) and operates efficiently across a broad temperature range. Its optimized internal geometry and precision-machined raceways minimize friction and heat generation, allowing for limiting speeds up to 9,500 rpm under grease lubrication. This specification makes the 8509 an ideal component for critical high-speed rotating equipment where vibration reduction and precise shaft guidance are paramount.
Choosing the SW 8509 ensures predictable performance and reduced total cost of ownership (TCO) in demanding environments such as electric motors, heavy-duty pumps, ventilation systems, and industrial gearboxes. The integrated contact seals eliminate the need for routine relubrication, maximizing uptime and simplifying maintenance schedules. SW’s commitment to tight tolerances (P6/ABEC 3 equivalent or better) guarantees alignment stability and extended operational lifespan, reflecting the highest standards of industrial durability and operational efficiency required by modern manufacturing facilities.
