- Category: Hardware › Bearings, rails & motion
- Kind: Standard part
- Basis: Koyo (JTEKT) self-aligning ball bearing supplement tables, checked on d, D, B against Emerson Bearing lists and between the 12xx / 22xx and 13xx / 23xx twins; McMaster-Carr linked for per-part CAD

**Exact dimensions.** Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part.

## Notes

- A self-aligning ball bearing has two rows of balls running in a spherical outer-ring raceway, so the shaft can tilt (about 2 to 3 degrees) against the housing without binding. It is the usual choice for long shafts, pillow blocks and fan or conveyor shafts that deflect or are not perfectly aligned. 12xx and 13xx are the narrow series; 22xx and 23xx are the wide series with the same bore and OD as 12xx and 13xx.
- Numbers: Koyo (JTEKT) self-aligning ball bearing supplement, cylindrical-bore tables (d, D, B, r min), 1200 and 1300 to 1322 plus 2200 and 2300 series. Emerson Bearing's lists are the independent check on d, D and B for 1200, 1201, 2200 to 2204 and 2301 to 2322 (all agree). Internal checks run by the generator: every 22xx row has the same d, D and r min as its 12xx twin and every 23xx row the same as its 13xx twin. 1300 does not appear in the Koyo table read.
- Files: 16 ring envelopes (1203 to 1210, 1305 to 1308, 2204 to 2208, 2305 to 2308): one solid ring with bore d, OD D, width B and corners rounded at r min. No balls, cage, spherical raceway or seals; ring faces are not stepped.
- Left out: tapered-bore (K) versions (1:12 taper, the bore diameter changes with position), the adapter sleeves, loads, speeds, mounting dimensions da, Da and ra, 126, 127 and 129 (Emerson lists them but Koyo's table starts at 1200), sizes above 110 mm bore, extended-inner-ring types (11xx, 112xx), sealed (2RS) versions.

## Questions

**What are the dimensions of a 1205 self-aligning ball bearing?**

Bore 25, OD 52, width 15 mm; r min 1 mm (Koyo).

**What are the dimensions of a 2205 bearing?**

Bore 25, OD 52, width 18 mm, r min 1 mm: the 22xx series is wider than 12xx with the same bore and OD.

**What are the dimensions of a 2305 bearing?**

Bore 25, OD 62, width 24 mm, r min 1.1 mm (Koyo and Emerson agree).

**What are the dimensions of a 1305 bearing?**

Bore 25, OD 62, width 17 mm, r min 1.1 mm.

**Is a 1205 the same size as a 6205?**

In bore, OD and width, yes: both are 25 x 52 x 15 mm (6205 deep-groove, see the deep-groove page); the 2205 is 18 mm wide with the same bore and OD.
