Cylindrical Roller Bearings SKF NUP204 ECP

The SKF NUP204 ECP cylindrical roller bearing supports shafts with a 20 mm bore as a fixed bearing in both axial directions.

The NUP204 ECP cylindrical roller bearing is a single-row roller bearing in the SKF Explorer performance class with an optimised internal design. With key dimensions of 20 mm inside diameter, 47 mm outside diameter and 14 mm width, this design can accommodate high radial loads. The outer ring has no lubrication groove. Thanks to the NUP design with fixed flanges and a loose flange disc, this component provides axial guidance for the shaft on both sides.

In which installation scenarios is the NUP204 ECP cylindrical roller bearing used as a fixed bearing?

Design engineers primarily use this design in bearing arrangements where high radial loads occur and precise axial fixation is required at the same time. Typical applications include bearing arrangements where, in addition to high radial forces, axial guidance forces in both directions must also be supported. As the open bearing has no integrated sealing washers, it is suitable for enclosed housings with an external lubricant supply. The component covers an operating temperature range from –30 to +120 degrees Celsius.

What are the advantages of combining a polyamide cage with P6 precision?

The integrated polyamide cage reduces the moving mass of the roller guide and promotes low-friction operation under normal operating conditions. In conjunction with the standard radial bearing clearance and dimensional accuracy to P0 or ABEC 1, the bearing fits into standardised housing fits. The improved running accuracy of class P6 (ABEC 3) also contributes to precise shaft concentricity, which reduces vibrations and operating noise in the drivetrain.
