Cylindrical Roller Bearings SKF N220 ECP

The SKF N220 ECP cylindrical roller bearing, with a 100 mm bore, offers high radial load-carrying capacity as a support bearing for industrial applications.

The N220 ECP cylindrical roller bearing is a single-row radial roller bearing in the SKF Explorer performance class with an optimised internal design. With a bore of 100 mm, an outer diameter of 180 mm and a width of 34 mm, the design can accommodate high radial loads. The rollers and inner ring form a rigid unit, whilst the flangeless outer ring compensates for axial displacement of the shaft. The open bearing operates with a standard radial clearance and is suitable for both oil- and grease-lubricated bearing arrangements.

What is the N220 ECP cylindrical roller bearing suitable for?

The N220 ECP cylindrical roller bearing primarily withstands high radial forces and compensates for axial length changes in the shaft without constraint. As the outer ring can be removed from both ends, the bearing can be fitted separately onto the shaft and housing, which facilitates installation and simplifies maintenance work on challenging bearing arrangements.

As a floating bearing, this design is suitable for shaft mountings where temperature-induced displacements need to be compensated for. The cylindrical rollers ensure uniform force transmission within the radial load range, whilst axial forces are absorbed separately by a fixed bearing.

What are the advantages of the N design for this roller bearing?

The N design is characterised by two fixed flanges on the inner ring, whilst the outer ring is flangeless. As a result, this cylindrical roller bearing functions purely as a floating bearing. It guides the shaft in the radial direction and allows axial displacement of the housing relative to the shaft. The polyamide cage contributes to low inertial forces and smooth running within a temperature range of -30 to +120 degrees.
