What are the dimensions of this SKF cylindrical roller bearing?

This bearing has a 30 mm bore diameter, a 72 mm outside diameter, and a width of 19 mm.

What axial loads can the NJ design accommodate?

With two flanges on the outer ring and one on the inner ring, it can locate the shaft axially in one direction.

What does the C4 clearance designation mean?

C4 indicates a radial internal clearance greater than normal (CN) or C3, suitable for high operating temperatures or press fits.

What material is the cage made from?

The cage is made from glass fibre reinforced polyamide (plastic), providing low friction and lightweight performance.

Does this cylindrical roller bearing come sealed?

No, this is an open bearing without seals, allowing you to lubricate it directly with your required grease or oil.

Dependable performance under heavy radial loads

Practical benefits

High radial load capacity: The single-row cylindrical roller bearing handles demanding radial forces smoothly at high rotational speeds.
Increased C4 clearance: You accommodate thermal expansion and elevated running temperatures without risking premature component wear.
Practical separable design: The NJ-design construction allows you to mount and dismount inner and outer rings independently.

In a nutshell

The right choise for

With the Skf nj 306 ECP/C4 single-row cylindrical roller bearing, you keep demanding drives and industrial machinery running smoothly. This open bearing easily handles heavy radial loads while locating the shaft axially in one direction through its practical nj design. If your equipment operates under high temperatures, the increased C4 clearance reliably accommodates thermal expansion to prevent bearing seizure. The lightweight glass-fibre reinforced polyamide cage reduces running friction and noise during high-speed rotation. Thanks to the separable construction, mounting and servicing on 30 mm shafts is straightforward and efficient.

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 on the inner ring, NJ design bearings can accommodate axial displacement in one direction. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
