SKF 51209 Thrust Ball Bearing

The SKF 51209 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 51209, this bearing features 45 mm bore (d), 92 mm outer diameter (D), and 20 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 89.5 kN and a basic static load rating (C0) of approximately 170 kN, with a reference rotational speed of around 2800 r/min depending on lubrication and mounting conditions.

The 51209 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 51209 is widely specified for rotating equipment at facilities such as Ma'aden Aluminium (Ras Al-Khair smelter pot-line fans) and NEOM (green hydrogen plant rotating equipment). 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.

Razz Middle East supplies the 51209 and a full range of associated SKF bearings, seals, lubricants and mounting tools for supply across Saudi Arabia. From our distribution network we provide delivery to the Eastern Province industrial corridor including Jubail and Dammam, as well as Riyadh, Jeddah and Yanbu, typically within 2 to 3 weeks as an indent order, delivered duty-paid. Our technical team can assist with bearing selection, interchange cross-referencing to NSK, FAG/Schaeffler and Timken equivalents, failure analysis and condition-monitoring recommendations.
