What are the dimensions of this bearing?

The bearing has a 40 mm bore, a 90 mm outside diameter, and a width of 23 mm.

What loads can the NJ design accommodate?

It is designed for heavy radial loads and can locate the shaft axially in one direction.

What material is the cage made from?

The ECP designation indicates a glass-fibre reinforced polyamide (plastic) cage.

Is this SKF cylindrical roller bearing sealed?

No, this is an open bearing without seals, allowing direct lubricant flow.

Is the inner ring separable for easier mounting?

Yes, the bearing features a separable design so the inner ring can be mounted separately.

Dependable performance under heavy radial loads

Practical benefits

High radial load capacity: With this Skf cylindrical roller bearing, you easily handle heavy radial forces and high rotational speeds.
Unidirectional axial location: Thanks to the NJ design, you securely locate the shaft against axial displacement in one direction.
Quick and easy mounting: The separable design enables you to mount, dismount, and inspect individual bearing components with minimal effort.

In a nutshell

The right choise for

With the Skf nj 308 ecp single row cylindrical roller bearing, you achieve dependable performance under heavy radial loads and high rotational speeds. Measuring 40 x 90 x 23 mm, this open bearing features an nj design that reliably locates the shaft axially in one direction, making it ideal for electric motors, pumps, and gearboxes. The lightweight glass-fibre reinforced polyamide cage reduces inertia and operational noise, while the separable design with normal radial internal clearance ensures quick, straightforward mounting and efficient maintenance during overhauls.
