2200 Series Self-aligning Ball Bearings

The wide version of the 1200 series — and only the width changes: at every bore code a 2200 has the same bore and the same outside diameter as the 1200, in a wider ring. A 2204 is 20 × 47 × 18 mm against 20 × 47 × 14 mm for the 1204, and a 2210 is 50 × 90 × 23 against 50 × 90 × 20. The extra width is the whole point of the series: it buys load capacity inside a housing that the 1300 series would not fit, because the outside diameter is still the 1200 one. Its model number leads with the width digit rather than the type digit.

Wide, not larger. Every figure on a 2200 other than the width is the one on the 1200 beside it. Both families are diameter series 2, so they share the outside-diameter ladder; the leading 2 says the bearing is the wider of the two width series, and the width is the only dimension that moves. A 2204 is 20 × 47 × 18 mm where a 1204 is 20 × 47 × 14 mm — same shaft, same housing bore, 4 mm more of the ring.

What the extra width is for. A wider ring means a wider raceway and a longer ball path, so a 2200 carries more radial load than the 1200 at the same shaft diameter without asking for a larger housing. That is the trade a width series offers: it spends axial space the designer may already have, rather than radial space around the shaft, which is usually the dimension that is actually tight.

Reading the designation. 2204 is the dimension series 22 followed by the bore code 04. Here, unlike the 1200 family, that figure carries both series digits — 2 for the width series and 2 for the diameter series. The type code is 1, the same one a 1204 carries, and in this family it is not written at all, so nothing in the number itself says the bearing is self-aligning; the series does. The bore code is the familiar one: 00, 01, 02 and 03 are 10, 12, 15, 17 mm, and from 04 upwards the code multiplies by five. So 2204 and 1204 take the same shaft and differ only in how much of the shaft they occupy.

Every designation in the table below links to its own page with the ISO 15 dimensions, the bore-code arithmetic, the same-bore comparison against every other series and type, and an explanation of why no radial clearance table appears for this type.

This series runs from a 10 mm to a 100 mm bore. The sub-library as a whole reaches 200 mm, and the widest single bearing in it is a 6340, 420 mm across, in the 6300 series. This one stops short of it.

d = bore diameter, D = outside diameter, B = width. All of them are ISO 15 standard values and are the same for every manufacturer. r s min is the minimum single chamfer dimension the plan gives; its matching maximum is in ISO 582, which is why the column says “min” and not an equality. The last column is derived: radial section = (D − d) / 2, the wall thickness you are working with when you size the housing. No load rating and no limiting speed appears here — see the bearings index for why.

Outside diameter × overall size in millimetres, for the 5 smallest bores in this database. The full charts, one per type, are on the bearings index. Reading a row is what a machine designer does when the shaft is already fixed: the bore does not change, the housing bore does. Across the type boundary the last number changes meaning — it is a width above and a height below — so compare within a type, then decide whether the job wants a ball bearing, a tapered roller or a thrust bearing at all.
