SKF 51117 Thrust Ball Bearing

The SKF 51117 Thrust Ball Bearing is a precision thrust ball bearing manufactured by SKF, the world's leading rolling bearing producer founded in Gothenburg, Sweden in 1907. Designated 51117, this bearing features 85 mm bore (d), 142 mm outer diameter (D), and 25 mm width (B), giving it a compact yet robust geometry suited to heavy-duty industrial rotating equipment. This thrust ball bearing is designed to carry pure axial loads in one direction, seating washer assemblies for vertical shaft and pump-thrust applications. It carries a basic dynamic load rating (C) of approximately 122.0 kN and a basic static load rating (C0) of approximately 242.5 kN, with a reference rotational speed of around 3000 r/min depending on lubrication and mounting conditions.

The 51117 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 51117 is widely specified for rotating equipment at facilities such as SAFCO (ammonia plant compressor bearings) and SEC (PP9 power generation turbine auxiliaries). 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.
