SKF 6309-2RS1 Deep Groove Ball Bearing Rubber Sealed

SKF 6309-2RS1 is a single-row deep groove ball bearing with seals on both sides (RS1), designed for radial loads and high-speed operation. It has a bore diameter of 45 mm (about 1.77 in) and an outer diameter of 100 mm, with a normal radial internal clearance (CN) and grease lubrication. The seals are nitrile rubber (NBR) on both faces, helping retain lubricant and prevent entry of contaminants. As an SKF Explorer-listed bearing, it delivers reliable low-friction performance under demanding conditions, with a basic dynamic load rating of 55.3 kN, a static load rating of 31.5 kN, and a maximum operating speed around 4,500 rpm. This makes it well-suited for electric motors, fans, conveyors, gearboxes, pumps, and other general-purpose machinery where compact size and long service life are required, all within the standard 6309 series footprint and bearing steel construction.
