## Notes

- GE..E (E series, ISO 12240-1) spherical plain bearings: a steel ball with a bore inside a steel outer ring, free to swivel in all directions; the ball is wider than the ring (B > C). They sit in rod ends, pivots and linkages. 'E' = standard series; the source table is the DO (maintenance-free) variant, listed with the E / ES names.
- Numbers: INA's GE..-DO table (d, D, B, C, dK, α); Kinex agrees on every row and adds the 5 mm size; Emerson Bearing confirms spot sizes. The 5 mm row (GE5E) is Kinex only. Tolerances (INA, same numbers): d 0 / −0.008 mm up to 17 mm, 0 / −0.01 mm for 20 to 30 mm; D 0 / −0.008 mm to 0 / −0.011 mm; B 0 / −0.12 mm; C 0 / −0.24 mm.
- Files: 10 solids (GE6E to GE30ES) as ball + outer ring fused: the ball dK cut to width B with the bore d, the ring D × C with its inner surface following the ball sphere. This is an envelope: the working gap, lube groove and slot are not drawn, and because the ball touches the ring it is one solid and does not swivel in the CAD.
- Left out: GE..-FO, GE..-LO, GE..-UK and maintenance-free liners, wide series GEG / GEH, load ratings, inch sizes.

## Mating features (exact size; open press / slide / run / socket by your process clearance, leave designed and clamp as drawn)

| feature | exact | mates with | fit | files |
|---|---|---|---|---|
| bore d | Ø6 to Ø30 (files GE6E to GE30ES) | pin or bolt of the same nominal diameter through the ball | slide | ge* |
| outside Ø D | Ø14 to Ø47 | housing bore of the same nominal diameter; width C of the outer ring sets the housing seat | press | ge* |

## Sizes

| bearing | bore d, mm | outside Ø D, mm | inner ring width B, mm | outer ring width C, mm | ball Ø dK, mm | tilt angle α |
