Dependable performance with Skf

Practical benefits

High radial load capacity: You manage heavy radial forces smoothly thanks to the robust single-row cylindrical roller design.
Double direction axial location: The NUP design accurately locates the shaft in both axial directions to ensure stable and reliable rotation.
Easy separable installation: The separable configuration lets you mount, dismount, and inspect individual bearing components quickly and effortlessly.

In a nutshell

The right choise for

With the Skf nup 2308 ecp single row cylindrical roller bearing, you gain exceptional stability and high radial load carrying capacity for demanding industrial machinery, gearboxes, pumps, and electric motors. Its nup design handles heavy radial forces while providing double-direction axial location to effectively prevent axial shaft drift during operation. The optimized polyamide cage minimizes operational friction and reduces running noise. Featuring a separable construction, a cylindrical bore of 40 x 90 x 33 mm, and standard cn radial internal clearance, this open bearing ensures quick, accurate mounting and straightforward maintenance.

Product description

Single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds. Having two integral flanges on the outer ring and one integral flange and one loose flange ring on the inner ring, NUP design bearings can locate the shaft axially in both directions. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
