SKF 30314 J2 Tapered Roller Bearing

The SKF 30314 J2 Tapered Roller Bearing is a precision single-row tapered roller bearing manufactured by SKF, the world's leading rolling bearing producer founded in Gothenburg, Sweden in 1907. Designated 30314 J2, this bearing features 70 mm bore (d), 169 mm outer diameter (D), and 40 mm width (B), giving it a compact yet robust geometry suited to heavy-duty industrial rotating equipment. This single-row tapered roller bearing (normal contact angle) carries combined radial and axial loads and separates into cone and cup assemblies for simple mounting and clearance adjustment. It carries a basic dynamic load rating (C) of approximately 221.0 kN and a basic static load rating (C0) of approximately 263.0 kN, with a reference rotational speed of around 3000 r/min depending on lubrication and mounting conditions.

The 30314 J2 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 30314 J2 is widely specified for rotating equipment at facilities such as NWC (Riyadh water transmission pumping stations) and Saudi Aramco (Shaybah NGL recovery trains). 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.
