Sizes: see table below
- 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.
