SKF NK55/25 Machined Ring Needle Roller Bearing
The SKF NK55/25 Machined Ring Needle Roller Bearing is a precision machined ring needle roller bearing manufactured by SKF, the world's leading rolling bearing producer founded in Gothenburg, Sweden in 1907. Designated NK55/25, this bearing features 55 mm bore (d), 68 mm outer diameter (D), and 25 mm width (B), giving it a compact yet robust geometry suited to heavy-duty industrial rotating equipment. This machined ring needle roller bearing provides very high radial load capacity in a minimal cross-section, ideal where radial space is restricted. It carries a basic dynamic load rating (C) of approximately 42 kN and a basic static load rating (C0) of approximately 92 kN, with a reference rotational speed of around 8500 r/min depending on lubrication and mounting conditions.
The NK55/25 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 NK55/25 is widely specified for rotating equipment at facilities such as SADAF (styrene monomer unit pumps) and NWC (Riyadh water transmission pumping stations). 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 NK55/25 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. Contact Razz Middle East at sales@razz.sa to request a quotation, confirm current stock of the NK55/25, or arrange scheduled deliveries supporting your plant maintenance and turnaround programmes in Riyadh and across the Kingdom of Saudi Arabia.
