FAG NNU4948-S-K-M-SP bearing

Bearing NNU4948-S-K-M-SP Bearing NNU4948-S-K-M-SP

Bearings extend the working life of wheels, pulleys, and other rotating parts by reducing friction and enabling parts to move smoothly. Also called slewing rings or slewing bearings, they are installed between two surfaces to keep parts aligned and support axial and radial loads.
