SKF - 6203-F604 - SKF High-temperature ball bearing

The SKF 6203F604 is a genuine SKF high-temperature deep groove ball bearing, specifically engineered for applications operating in extreme heat conditions. This bearing features a 17 mm bore diameter, 40 mm outer diameter, and 12 mm width, conforming to standard dimensions for the 6203 series. It is designed to withstand continuous operating temperatures up to 350 °C (660 °F) and intermittent temperatures up to 400 °C (750 °F). The F604 designation indicates special internal design and materials optimized for high-temperature performance, including a cage made from sheet steel, radial internal clearance greater than C5, and a special polyalkylene glycol/graphite mixture lubricant. This robust construction ensures reliable operation and extended service life in demanding industrial environments where conventional bearings would fail.
