SKF 22311 E Spherical Roller Bearing

The SKF 22311 E Spherical Roller Bearing is a precision self-aligning spherical roller bearing manufactured by SKF, the world's leading rolling bearing producer founded in Gothenburg, Sweden in 1907. Designated 22311 E, this bearing features 55 mm bore (d), 146 mm outer diameter (D), and 51 mm width (B), giving it a compact yet robust geometry suited to heavy-duty industrial rotating equipment. The 22300 E series offers a wide, high-capacity cross-section for the heaviest radial and shock loads in mining, crushing and material-handling duties. It carries a basic dynamic load rating (C) of approximately 370 kN and a basic static load rating (C0) of approximately 420 kN, with a reference rotational speed of around 2000 r/min depending on lubrication and mounting conditions.

The 22311 E 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 22311 E is widely specified for rotating equipment at facilities such as Ma'aden Aluminium (Ras Al-Khair smelter pot-line fans) and MAADEN (Gold mine conveyor drive systems). 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.
