Cylindrical Roller Bearings SKF NU326 ECM

The SKF NU326 ECM cylindrical roller bearing, with a 130 mm bore, brass cage and a separable inner ring, offers high radial load-carrying capacity for demanding industrial applications.

The NU326 ECM cylindrical roller bearing is a single-row radial roller bearing designed for high mechanical loads. With key dimensions of 130 mm inner diameter, 280 mm outer diameter and 58 mm width, this unit can accommodate substantial radial forces. Designed as an open bearing, this model can be flexibly integrated into existing lubrication systems. This design is used where rigid mountings with high load-carrying capacity are required.

What is the NU326 ECM cylindrical roller bearing suitable for in operation?

The NU326 ECM cylindrical roller bearing is designed for use as a pure non-locating bearing. In the NU design, two fixed flanges on the outer ring guide the cylindrical rolling elements, whilst the inner ring has no flanges. This enables the component to compensate freely for axial length changes, such as those caused by thermal expansion of shafts. Typical applications include bearing arrangements subject to high radial forces, where operational longitudinal displacements must be accommodated.

What properties do the brass cage and NU design offer?

The design with a brass cage gives the bearing high mechanical stability against vibrations and shock loads. Furthermore, the separable design simplifies handling: as the inner ring can be removed from both sides, the inner and outer rings can be mounted separately onto the shaft and housing. The permissible temperature range is from –30 to +150 degrees Celsius. Dimensional accuracy complies with Class P0/PN (ABEC 1), whilst running accuracy in accordance with Class P6 (ABEC 3) ensures precise guidance.
