Product Description

The SKF Cylindrical Roller Bearing 308 (MPN NU 308 ECM) is a general-purpose cylindrical roller bearing with an NU design, featuring a 40 mm bore, 90 mm OD, and 23 mm overall width. It is constructed with alloy steel rings and a brass cage, and is supplied in metric measurements under bearing industry number 308.

Frequently Asked Questions

What is the SKF NU 308 ECM cylindrical roller bearing used for?

The SKF NU 308 ECM is a general-purpose cylindrical roller bearing designed for high radial loads in industrial machinery such as gearboxes, pumps, compressors, and electric motors. Its NU design allows axial shaft displacement, making it suitable for applications where thermal expansion must be accommodated.

What are the specifications of the SKF 308 cylindrical roller bearing?

The SKF 308 (MPN NU 308 ECM) has a 40 mm bore, 90 mm OD, and 23 mm overall width. It features alloy steel rings, a brass cage, and metric measurements. The NU design supports radial loads and permits axial movement of the shaft relative to the housing.

Where to buy SKF NU 308 ECM bearings worldwide?

You can source the SKF NU 308 ECM bearing from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine SKF bearings to industrial buyers globally.

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

To select the correct SKF cylindrical roller bearing, match the bore, OD, and width to your shaft and housing dimensions. Consider load type: NU designs handle radial loads and allow axial shaft movement. Verify operating temperature and speed limits; the brass cage in the NU 308 ECM suits moderate speeds and temperatures.

Used in

Common applications for SKF
Heavy machinery gearboxes — SKF spherical roller bearings (e.g., 24056 CCK30/W33) for high radial load capacity
Electric motor repair — SKF cylindrical roller bearings (e.g., NJ 307 ECP/C3) for free axial expansion
Pump shaft sealing — SKF CRWA1 rotary shaft seals (e.g., 17100) for fluid retention in rotating equipment
Conveyor system maintenance — SKF wear sleeves (e.g., 99274) to protect shafts from seal abrasion
Machine tool spindles — SKF angular contact bearings (e.g., 7413 BGBM) for axial load support in duplex sets
Industrial fan assemblies — SKF spherical roller bearings (e.g., 23044 CC/W33) for misalignment accommodation
