Cylindrical Roller Bearings SKF NUP209 ECP

The SKF NUP209 ECP cylindrical roller bearing is a single-row fixed bearing with a 45 mm bore, offering high radial load-carrying capacity and axial guidance.

The SKF NUP209 ECP cylindrical roller bearing is an open, single-row rolling bearing designed for industrial applications with demanding load profiles. With an inside diameter of 45 mm, an outside diameter of 85 mm and a width of 19 mm, the design accommodates high radial forces. The integrated polyamide cage guides the cylindrical rollers precisely and quietly. At the same time, the NUP design allows axial forces to be accommodated in both directions thanks to fixed flanges on the outer ring and a fixed flange and a loose flange disc on the inner ring.

What are the applications of the NUP209 ECP cylindrical roller bearing?

This design is used in bearing arrangements where, in addition to high radial loads, axial forces occur on both sides. As a fixed bearing, the NUP design secures the shaft axially relative to the housing. This eliminates the need for an additional axial bearing in many bearing arrangements, enabling compact installation spaces and a rigid shaft mounting.

What are the key features of the polyamide cage in the ECP design?

The polyamide material reduces the weight of the rotating cage assembly and minimises friction at the contact surfaces. This design combines this material with an optimised internal structure that promotes even load distribution within the roller set. The operating temperature range is specified as -30 to +120 degrees. As the bearing is of an open design, provision must be made for an external lubricant supply and housing seals to protect against contamination.
