Cylindrical Roller Bearings SKF NU2319 ECJ

The SKF NU2319 ECJ cylindrical roller bearing, measuring 95 × 200 × 67 mm, serves as a separable support bearing designed to accommodate high radial loads.

The single-row cylindrical roller bearing NU2319 ECJ from SKF is designed for demanding industrial applications. Thanks to the line contact between the rolling elements and raceways, this design can accommodate heavy radial loads. As an open design without seals, the bearing is intended for operation with an external lubricant supply. With key dimensions of a 95 mm bore, 200 mm outside diameter and 67 mm width, it belongs to the wider size series for high loads.

What is the NU2319 ECJ cylindrical roller bearing suitable for?

This rolling bearing is primarily used in bearing arrangements subject to high radial loads. Designed as a floating bearing, the construction compensates for thermal length changes in the shaft directly within the bearing. The optimised internal design in the SKF Explorer version reduces friction and heat generation under high loads. The integrated sheet steel cage guides the cylindrical rollers and is suitable for operating temperatures ranging from –30 to +150 degrees Celsius.

What are the advantages of the design with a removable inner ring?

In the NU design, the inner ring has no flanges and can be completely withdrawn from both sides. This considerably simplifies assembly and disassembly in the case of tight fits on the shaft and in the housing. Both bearing rings can be fitted separately, which reduces installation errors and shortens maintenance times. When designing the application, please note that this bearing cannot accommodate axial loads and must therefore be combined with a separate fixed bearing.
