Product Description

SKF NU 313 ECJ/C3 is a premium roller bearing engineered for industrial applications requiring reliable radial load support. This model features a 65 mm inner diameter, a 140 mm outer diameter, and a 33 mm race width, making it ideal for a wide range of rotary machinery.

The bearing incorporates a single row of cylindrical rolling elements, offering superior load capacity and stability. It is equipped with shielded end types to prevent ingress of contaminants, thereby reducing maintenance frequency and prolonging bearing life. The sheet-metal cage design reduces bearing mass and allows for rotational stability, even in environments subject to shock loads.

Single row cylindrical roller bearing optimised for radial loads. C3 internal clearance accommodates heat expansion and ensures smooth performance under elevated temperatures. Dynamic load rating of 212 kN and static load rating of 196 kN enable the bearing to withstand heavy operational and stationary loads.

Limiting speed up to 6000 rpm facilitates medium to high-speed rotation. Shielded ends defend against debris and contamination for extended service intervals. Sheet-metal cage offers lower inertia and increased tolerance to shock loads.

Tapered cylindrical bore allows for easy installation with straight journal shafts. Precision manufactured in Germany for consistent quality and performance.

The SKF NU 313 ECJ/C3 is commonly found in industrial gearboxes, conveyor rollers, electric motor shaft assemblies, pumps, compressors, and rotary tables used in machine tools. The C3 clearance specification provides extra internal play to compensate for thermal expansion, making it suitable for high-temperature and high-speed environments.

Typical industrial sectors for this bearing include manufacturing, water treatment, construction, HVAC systems, and heavy machinery. Its robust construction and shielding features ensure minimum downtime and maintenance, especially in environments with high contamination risks.
