The SW 6303-2RS is a robust single-row deep groove ball bearing engineered for high performance and reliability in demanding industrial environments. Featuring a standard 17mm bore (d), 47mm outer diameter (D), and 14mm width (B), this bearing utilizes high-quality chrome steel (typically SAE 52100) and is manufactured to P0 precision tolerances, ensuring smooth, low-noise operation. The deep raceway grooves and close conformity between the races and balls allow the bearing to handle significant radial and moderate axial loads in both directions. The 2RS designation confirms the presence of contact rubber seals on both sides, effectively retaining factory lubrication while preventing contamination ingress from dust, moisture, and fine debris.
Designed specifically to minimize maintenance and maximize uptime, the SW 6303-2RS is pre-lubricated with high-grade, wide-temperature-range grease, making it ready for immediate installation across a wide range of machinery. Its superior sealing system makes it the ideal choice for applications exposed to harsh elements, such as agricultural equipment, power tools, electric motors, gearboxes, and pumps operating at moderate to high speeds. By choosing the SW brand, customers benefit from optimized internal geometry that reduces operational friction and heat generation, leading to extended service life and reliable, consistent power transmission under continuous duty cycles.
