The SW 6305-2RS is a precision-engineered single-row deep groove ball bearing constructed from premium high-carbon chrome steel (SAE 52100) to ensure superior hardness, dimensional stability, and extended fatigue life under heavy cyclic loads. Featuring robust contact rubber seals (2RS) on both sides, this bearing is permanently lubricated with high-grade industrial grease, offering maximum protection against moisture, dust, and corrosive industrial contaminants. Meeting stringent ISO 927 standards, the 6305-2RS provides optimal radial load capacity and moderate axial load capability, making it the default choice for high-speed, high-reliability applications where uptime is critical.
Designed specifically for demanding industrial environments—including operations in conveyors, electric motors, centrifugal pumps, and gearboxes—the SW 6305-2RS guarantees minimized maintenance overhead and reduced unscheduled downtime. Its advanced sealing technology eliminates the need for external lubrication systems while protecting the raceways from particulate ingress, significantly prolonging the service life compared to standard open or shielded bearings. Choosing SW is an investment in operational efficiency, utilizing a component engineered for long-term durability and consistent, low-vibration performance under continuous operation.
