SNFA VEB45 NS 7CE3 UL Ceramic Super Precision Bearing

SNFA VEB45 NS 7CE3 UL is a ceramic, super-precision, single-row angular-contact ball bearing designed for high-speed, high-accuracy applications. It uses silicon nitride (Si3N4) ceramic balls (NS) in a precision ABEC 7-class variant (7CE3), with a bore of 45 mm, an outer diameter of 68 mm, and a width of 12 mm. This is a hybrid bearing, typically pairing ceramic balls with steel races to deliver low friction and long life under demanding spindle and precision-motion service. Commonly employed in CNC machine-tool spindles and other high-precision equipment that must support combined radial and axial loads with tight running accuracy.
