Product Description

The SKF Cylindrical Roller Bearing: 304 is a general-purpose cylindrical roller bearing with an NU design, featuring a 20 mm bore, 52 mm OD, and 15 mm overall width. Manufactured by SKF, this metric bearing is constructed from alloy steel and carries the manufacturer part number NU 304 ECP.

Frequently Asked Questions

What is the SKF Cylindrical Roller Bearing NU 304 ECP used for?

The SKF NU 304 ECP cylindrical roller bearing is used in general-purpose industrial machinery that requires high radial load capacity and moderate speed. Common applications include electric motors, gearboxes, pumps, compressors, and conveyor systems. Its separable NU design allows axial displacement of the shaft relative to the housing, accommodating thermal expansion.

What are the specifications of the SKF Cylindrical Roller Bearing 304?

The SKF Cylindrical Roller Bearing 304 has a 20 mm bore, 52 mm OD, and 15 mm overall width. It is a metric bearing with an NU design, made from alloy steel. The manufacturer part number is NU 304 ECP, and the bearing industry number is 304. This SKF bearing is designed for general-purpose radial load applications.

Where to buy SKF Cylindrical Roller Bearing NU 304 ECP worldwide?

You can source the SKF Cylindrical Roller Bearing NU 304 ECP worldwide through 3G Electric, a global industrial equipment distributor established in 1990. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time. 3G Electric supplies genuine SKF bearings to customers around the world.

How to select the correct SKF cylindrical roller bearing for an application?

To select the correct SKF cylindrical roller bearing, first determine the required bore size, outer diameter, and width — for example, 20 mm bore, 52 mm OD, 15 mm width for the NU 304 ECP. Consider the radial load, speed, operating temperature, and whether axial displacement is needed. The NU design allows shaft movement. Always verify the manufacturer part number and ring material, such as alloy steel.

Used in

Common applications for SKF
Heavy machinery gearboxes — SKF spherical roller bearings (e.g., 24056 CCK30/W33) for high radial load capacity
