F625-2RS Bearings

Ten F625-2RS flanged miniature ball bearings for 5 mm shaft/idler builds. Each bearing is the flanged, double-rubber-sealed 625 size: 5 mm ID × 16 mm OD × 5 mm wide, with an approximately 18 mm flange OD.

Why use F625-2RS instead of a plain 625 bearing?

• Built-in flange: helps locate the bearing against a printed part, plate, or pulley stack where a plain bearing can walk sideways.
• 2RS rubber seals: contact seals on both sides help keep dust and plastic debris out of the races.
• Drop-in metric sizing: the 5 mm bore matches common small shafts, pins, and idler hardware used in 3D-printer motion and extruder assemblies.

Fitment and related bearing sizes

Use F625-2RS where the design specifically calls for a flanged 5 × 16 × 5 mm bearing. If the flange is not needed, use 625-2RS Bearings instead. For other flanged bearing sizes in the same motion-hardware family, compare F695-2RS Flanged Ball Bearing and F623-RS Bearings.

Gotchas

• This is the flanged F625-2RS bearing, not a plain 625-2RS bearing.
• Confirm your printed part or BOM calls for 5 × 16 × 5 mm with a flange before ordering.
• This listing is a 10-pack.
