Summarized by Shop
The F623-2RS is a flanged miniature deep-groove ball bearing for 3mm shafts, double rubber-sealed (2RS) and pre-greased. The flange locates the bearing against a printed or machined face, which makes it the go-to for Voron 0 and other 3D printer idlers and extruder/filament-path pulleys that ride on a 3mm shoulder bolt or pin.
