What are the exact dimensions of this bearing?

The SKF NUP 306 ECP bearing has a 30 mm bore (inside diameter), a 72 mm outside diameter, and a width of 19 mm.

How does the NUP design handle axial loads?

It features two integral flanges on the outer ring, plus one fixed flange and one loose flange ring on the inner ring, locating the shaft axially in both directions.

What does the ECP suffix signify?

E indicates an optimized internal design for higher load ratings, while CP denotes a glass-fibre reinforced polyamide (plastic) cage.

Is this SKF bearing sealed?

No, this is an open bearing without seals and requires external lubrication.

What is the radial internal clearance of this bearing?

This bearing has standard normal radial internal clearance (CN).

High radial capacity for industrial machinery

Practical benefits

High radial load capacity: You manage heavy radial forces and high operating speeds reliably with optimized roller geometry.
Double direction axial location: The NUP 306 ECP design firmly locates the shaft axially in both directions.
Quick and easy mounting: You benefit from separable components that simplify installation, dismounting, and regular maintenance procedures.

In a nutshell

The right choise for

With the Skf nup 306 ecp single row cylindrical roller bearing, you ensure dependable and rigid shaft support in demanding industrial machinery. Sized at 30 x 72 x 19 mm, this bearing is built to handle heavy radial loads and high operating speeds with ease. Thanks to the nup design with integral flanges and a loose flange ring, you firmly locate the shaft axially in both directions. The optimized internal geometry and glass-fibre reinforced polyamide cage reduce friction and noise in electric motors, gearboxes, and pumps. In addition, the separable, open design makes mounting, dismounting, and external lubrication fast and straightforward.
