SKF 6306-C3 Deep Groove Ball Bearing

The SKF 6306-C3 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 6306-C3, this bearing features 30 mm bore (d), 72 mm outer diameter (D), and 19 mm width (B), giving it a compact yet robust geometry suited to heavy-duty industrial rotating equipment. It is supplied with C3 internal radial clearance, greater than normal, to accommodate thermal expansion and interference fits in hot Saudi operating conditions. It carries a basic dynamic load rating (C) of approximately 29.6 kN and a basic static load rating (C0) of approximately 16 kN, with a reference rotational speed of around 13000 r/min depending on lubrication and mounting conditions.

The 6306-C3 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 6306-C3 is widely specified for rotating equipment at facilities such as Ma'aden Aluminium (Ras Al-Khair smelter pot-line fans) and SEC (Ghazlan power plant cooling water pumps). 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.
