SKF NU38 ECP Cylindrical Roller Bearing

The SKF NU38 ECP Cylindrical Roller Bearing is a precision single-row cylindrical roller bearing manufactured by SKF, the world's leading rolling bearing producer founded in Gothenburg, Sweden in 1907. Designated NU38 ECP, this bearing features 40 mm bore (d), 108 mm outer diameter (D), and 24 mm width (B), giving it a compact yet robust geometry suited to heavy-duty industrial rotating equipment. This single-row cylindrical roller bearing (ECP polyamide cage) offers very high radial load capacity and is separable for easy mounting, with the NU3-type ribs determining axial guidance. It carries a basic dynamic load rating (C) of approximately 134.0 kN and a basic static load rating (C0) of approximately 141.0 kN, with a reference rotational speed of around 2500 r/min depending on lubrication and mounting conditions.

The NU38 ECP 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 NU38 ECP is widely specified for rotating equipment at facilities such as Ma'aden Aluminium (Ras Al-Khair smelter pot-line fans) and SWCC (Jubail desalination high-pressure pumps). 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 stocks the NU38 ECP and a full range of associated SKF bearings, seals, lubricants and mounting tools for fast supply across Saudi Arabia. From our distribution network we provide rapid delivery to the Eastern Province industrial corridor including Jubail and Dammam, as well as Riyadh, Jeddah and Yanbu, typically within 24 to 48 hours for stocked sizes. Our technical team can assist with bearing selection, interchange cross-referencing to NSK, FAG/Schaeffler and Timken equivalents, failure analysis and condition-monitoring recommendations.
