Cylindrical Roller Bearings SKF NU216 ECP

The SKF NU216 ECP cylindrical roller bearing is a separable single-row bearing with a polyamide cage, designed for high radial loads, with dimensions of 80x140x26 mm.

The SKF NU216 ECP cylindrical roller bearing is designed as a single-row roller bearing for demanding industrial applications involving purely radial force transmission. Thanks to the line contact between the rolling elements and raceways, this design with an optimised internal structure can accommodate substantial radial loads. With a bore of 80 mm, an outer diameter of 140 mm and a width of 26 mm, this open roller bearing meets standard dimensions in mechanical engineering. Manufactured to tolerance class P0 for dimensional accuracy and P6 for running accuracy, it ensures smooth concentricity.

What is the NU216 ECP cylindrical roller bearing suitable for in mechanical engineering?

This design is primarily used where high radial loads occur and shaft expansion must be compensated for without restriction. The NU design functions as a non-locating bearing, in which the inner ring has no flanges and can be removed from both sides. This allows the shaft to slide axially through the bearing with low friction in the event of temperature-induced length changes. Typical applications include industrial bearings subjected to purely radial loads, operating within a temperature range of -30 to +120 degrees and utilising external housing seals.

What are the advantages of the polyamide cage and the NU design?

The abbreviation ECP denotes the combination of the optimised internal geometry of the Explorer series and a lightweight polyamide cage. This cage guides the cylindrical rollers with low friction and performs well under rapid acceleration as well as at constant speeds. As the inner ring of the non-locating bearing can be removed from both sides, the inner and outer rings are fitted separately onto the shaft and housing seat. The open design requires a targeted supply of lubricant via the bearing environment, as well as an external seal to protect against dirt particles.
