SKF 6309 Deep Groove Ball Bearing

The SKF 6309 Deep Groove Ball Bearing is a precision deep groove ball bearing manufactured by SKF, the world's leading rolling bearing producer founded in Gothenburg, Sweden in 1907. Designated 6309, this bearing features 45 mm bore (d), 100 mm outer diameter (D), and 25 mm width (B), giving it a compact yet robust geometry suited to heavy-duty industrial rotating equipment. It carries a basic dynamic load rating (C) of approximately 55.3 kN and a basic static load rating (C0) of approximately 31.5 kN, with a reference rotational speed of around 8500 r/min depending on lubrication and mounting conditions.

The 6309 is engineered with SKF's high-grade chrome steel raceways, precision-ground rolling elements and optimised internal geometry to reduce friction, running temperature and noise. This makes it particularly well suited to the demanding thermal conditions of the Saudi Arabian climate, where ambient temperatures regularly exceed 50 degrees Celsius and airborne dust and sand place severe demands on sealing and lubrication. SKF's seal and clearance options help maintain a clean lubricant film, extending grease life and reducing unplanned downtime in desert and coastal Eastern Province environments where humidity and salt-laden air accelerate corrosion.

In Saudi industry the 6309 is widely specified for rotating equipment at facilities such as SABIC (Jubail petrochemical compressor trains) and Saudi Aramco (Ras Tanura refinery rotating equipment). Typical duties include electric motors, pumps, fans, gearboxes, compressors and conveyor systems across the oil and gas, petrochemical, desalination, power generation and mining sectors. SKF bearings are accepted on major Saudi approved vendor lists including the Saudi Aramco AVL, and are SASO compliant for use throughout the Kingdom.
