# Flanged ball bearings F6xx and MF: F623, F624, F625, F688, F695, F608 and more: bore, OD, width, flange diameter and thickness

> What are the dimensions of a flanged ball bearing such as F623ZZ, F624ZZ, F625ZZ, F688ZZ, F695ZZ or F608ZZ: bore, OD, width, flange diameter and flange thickness?

- Category: Hardware › Bearings, rails & motion
- Kind: Standard part
- Basis: NSK flanged miniature bearing table and product pages (MF105, MF126), a distributor's F-series list that matches NSK on every readable row, spot checks on F623 / F608 / F688; McMaster-Carr linked for CAD

**Exact dimensions.** True size, with no tolerance added.

## Notes

- Flanged deep-groove bearings add a thin collar on one outer-ring face that stops the bearing against a plate, so the pocket is a simple stepped hole. F6xx is the flanged form of the 6xx series (F623 = 623 with a flange, 3 × 10 × 4); MF is the metric extra-small series with flange. The bearings in 3D printers and extrusion systems are mostly F623, F624, F625, F688, F695 and F608, all in the table.
- Numbers: the F-series list is a distributor's catalogue of the same parts McMaster stocks (skdin.com). Its first rows match NSK's flanged-bearing table for every readable row (F681 to F602ZZ, 14 designations, bore, OD, width, flange Ø and thickness all equal); F623 also matches kugellager-express (DIN 625-1) and RobotShop, F608ZZ matches skdin's product page. MF41X, MF52B, MF62 and MF72 are NSK table rows, MF105 and MF126 are NSK's own product pages (the designations carry MC5P5 / MC5P6 precision suffixes there).
- Flange thickness is the one soft number. F688ZZ: the distributor table gives flange 18 × 1.1 mm (open: 1.0); Digitec lists 18 × 1 mm; the existing 'ball-bearings-metric' page of this site uses 1.0 for F688. Treat the F688 shielded flange thickness as 1.0 to 1.1 mm. The F688ZZ file here uses 1.1 (the distributor table); the other file thicknesses agree wherever a second source exists (F623, F608).
- Files: one solid per bearing (17 F-series shielded/sealed versions, plus MF105 and MF126): a ring with bore, OD, width and the flange on one face. No races, balls, shields or chamfers, which the tables do not give. Pocket sizes should be the bearing OD with your process allowance; the flange sits in a counterbore of its own diameter.
- Left out: the other ~110 designations NSK lists (only 20 of 149 rows were readable), tolerances and chamfer radii, load ratings, inch flanged bearings (McMaster stocks them; no table was read), and F-series bearings above 8 mm bore (F6000-type, in the existing 'ball-bearings-metric' page only for F6000).
