Cylindrical Roller Bearings SKF NU215 ECP/C3

SKF NU215 ECP/C3 single-row cylindrical roller bearing with a 75 mm bore, polyamide cage and C3 clearance for radial loads in free-end applications.

The SKF NU215 ECP/C3 cylindrical roller bearing is a radial-load-capable rolling bearing for industrial applications with a purely free-end function. With a bore of 75 mm, an outer diameter of 130 mm and a width of 25 mm, this single-row component can accommodate high radial forces. The inner ring, which can be removed from both ends, facilitates assembly and allows for separate fit selection for the shaft and housing.

In which bearing arrangements is the NU215 ECP/C3 cylindrical roller bearing used?

This non-locating bearing compensates for operational length expansion of the shaft without constraint within the raceway. The NU design guides the cylindrical rollers via two fixed flanges on the outer ring, whilst the flangeless inner ring allows axial displacement in both directions. Thanks to its optimised internal design and low-friction polyamide cage, this component is particularly suitable for shaft guides where high radial forces are transmitted without an axial guidance function.

What distinguishes the ECP/C3 design with a polyamide cage and increased bearing clearance?

The designation ECP indicates the optimised internal geometry in combination with a lightweight polyamide cage that reacts elastically to impact loads. The radial bearing clearance C3 deliberately provides more radial play than the standard version. This increased clearance counteracts bearing stress should temperature differences arise between the inner and outer rings or should tight fits restrict the operating clearance. External sealing and lubrication must be provided to ensure reliable operation.
