> What are the dimensions of a 22205, 22206, 22208, 22210, 22308 or 22310 spherical roller bearing: bore, OD, width and r?

- Category: Hardware › Bearings, rails & motion

**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

- Spherical roller bearings have two rows of barrel rollers running in a spherical outer raceway, so they carry heavy radial load, some axial load in both directions, and tolerate shaft misalignment: gearboxes, conveyors, crushers, mixers, bearing blocks. 222xx and 223xx are two dimension series: the bore code is the last two digits times 5 (22205 = 25 mm, 22308 = 40 mm), and at the same bore a 223xx has a larger OD and a greater width than the 222xx.
- Numbers: Koyo (JTEKT) spherical roller bearing catalogue pages for d, D, B and r min (22205 to 22222 and 22308 to 22320, cylindrical-bore 'RHR' rows), with Emerson Bearing's 22200 and 22300 lists as the independent check: all 30 Koyo rows match Emerson on d, D and B. Emerson's lists also give 22224 to 22238 and 22322 to 22348; those rows have no r min because Koyo's pages read stop there. The Emerson list prints suffixes E and W33; they do not change d, D or B in the rows read.
- Files: 13 ring envelopes (22205 to 22212 and 22308 to 22312): one solid ring, bore d, OD D, width B, corners rounded at r min. No outer-ring lubrication groove, rollers, cage or guide ring.
- Left out: the tapered-bore versions (K, K30), the 213xx, 230xx, 231xx, 232xx, 240xx series that sit in the same Koyo pages, adapter sleeves, self-aligning ball bearings (12xx, 13xx), load ratings, speed limits, 22222 to 22238 and 22322 to 22348 r values, inch sizes.

## Questions

**What are the dimensions of a 22205 spherical roller bearing?**

Bore 25, OD 52, width 18 mm; r min 1 mm.

**What are the dimensions of a 22208 spherical roller bearing?**

Bore 40, OD 80, width 23 mm; r min 1.1 mm.

**What are the dimensions of a 22308 spherical roller bearing?**

Bore 40, OD 90, width 33 mm; r min 1.5 mm.

**What is the difference between 222xx and 223xx?**

Same bore for the same last two digits; the 223xx has a larger OD and width: 22208 is 40 x 80 x 23, 22308 is 40 x 90 x 33.

**Is there a CAD file for 22208?**

A ring envelope (bore, OD, width, rounded corners) is on this page as STEP and STL; the full bearing with rollers and cage is on the maker's CAD pages linked below.
