SKF QJ207 MA Four-Point Contact Ball Bearing

The SKF QJ207 MA Four-Point Contact Ball Bearing is a precision four-point contact ball bearing manufactured by SKF, the world's leading rolling bearing producer founded in Gothenburg, Sweden in 1907. Designated QJ207 MA, this bearing features 35 mm bore (d), 72 mm outer diameter (D), and 17 mm width (B), giving it a compact yet robust geometry suited to heavy-duty industrial rotating equipment. This four-point contact design (MA machined brass cage) carries axial loads in both directions within a single bearing, saving space in compressor and gearbox shaft locations. It carries a basic dynamic load rating (C) of approximately 33.8 kN and a basic static load rating (C0) of approximately 23.6 kN, with a reference rotational speed of around 11000 r/min depending on lubrication and mounting conditions.

The QJ207 MA 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 QJ207 MA is widely specified for rotating equipment at facilities such as NEOM (Oxagon industrial city utilities) and SAFCO (ammonia plant compressor bearings). 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.
