Cylindrical Roller Bearings SKF NU213 ECM/C3

The SKF NU213 ECM/C3 cylindrical roller bearing, measuring 65x120x23 mm, offers high radial load capacity, C3 clearance and a solid brass cage.

The SKF NU213 ECM/C3 cylindrical roller bearing is a single-row roller bearing with a 65 mm bore, 120 mm outer diameter and 23 mm width. As an open idler bearing, the design accommodates high radial forces and allows for the axial compensation of length changes directly at the bearing location. Thanks to its optimised internal design in combination with a brass cage, this component performs reliably under demanding operating conditions in continuous industrial use as well as during rapid repairs.

What is the NU213 ECM/C3 cylindrical roller bearing suitable for as a non-locating bearing?

This single-row cylindrical roller bearing is primarily designed to accommodate high radial loads in radially guided shaft mountings. The NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless and removable from both sides. This allows the shaft to compensate for thermal expansion relative to the housing without restriction. As this is an open bearing without an integrated seal, lubrication is provided by the surrounding housing.

What are the advantages of the brass cage and the C3 clearance?

The ECM design combines an optimised internal geometry with a dimensionally stable brass cage. This cage maintains the precise spacing between the rollers even under high acceleration or vibration. The slightly increased C3 radial clearance counteracts bearing stress should temperature differences arise between the inner and outer rings or should tight fits reduce the operating clearance. The component covers a temperature range from -30 to +150 degrees and meets the P6 running accuracy standard.
