FAQ

Question?
Is this NU 308 bearing interchangeable with a modern SKF NU 308 ECP?

Answer

Yes, the principal dimensions (40x90x23 mm) are identical, making it mechanically interchangeable. However, modern ECP (Explorer Class) bearings feature optimized internal geometry and materials for higher load capacity and longer life. For critical applications, consult your engineer.

Question?
What does the 'NU' designation mean for this SKF bearing?

Answer

The 'NU' designation indicates that the bearing has two integral flanges on the outer ring and a smooth, flangeless inner ring. This design allows the shaft to move axially relative to the housing in both directions.

Question?
This bearing is from 1979. Is the lubricant still effective?

Answer

The bearing is supplied preserved in its original wax paper, which protects it from corrosion. Before installation, it is best practice to clean off the preservation grease and apply the appropriate, fresh lubricant specified for your application.
