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.
