6200 Series Deep Groove Ball Bearings

The light series and the one most machines are actually built around. Larger across and wider than the 6000 and the 16000, smaller than the 6300 and the 6400, so it sits mid-envelope for a given shaft. It runs to a 300 mm bore; the 6400 stops at 100 mm, so past that bore the only step above this one is the 6300.

The 6200 series is the light diameter series — the digit 2 in the second position. At any given bore it sits between the extra-light 6000 series and the medium 6300 series on outside diameter, width and load capacity, and that position — big enough to carry a real load, small enough to fit most housings — is why it is the most widely stocked series in the family. On a 20 mm shaft a 6204 is 47 mm across and 14 mm wide; the extra-light 6004 is 42 × 12, the medium 6304 is 52 × 15 and the heavy 6404 is 72 × 19.

The reason the light series became the default is a straightforward trade-off: the housing has to grow compared with an extra-light bearing, but the capacity bought by that extra outside diameter is usually cheaper than going to a medium series or a roller bearing. Nothing about that is a property of the standard — it is general engineering practice, and the numbers that decide it are the dimensions on these pages plus the load rating from the catalogue of the bearing you actually buy.

The series runs from 6200 (10 mm bore, 30 mm outside diameter, 9 mm wide) to 6260 (300 mm bore, 540 mm outside diameter, 85 mm wide) in the 37 designations tabulated here. The 6204 and 6205 in the middle of that range are probably the two most common rolling bearings in existence; they are also the two most commonly counterfeited, which is a reason to buy from a distributor who can show you the maker's documentation rather than from a listing that only repeats the dimensions.

Every designation in the table below links to its own page with the ISO 15 dimensions, the bore-code arithmetic, the ISO 5753-1 clearance ranges for its bore, and the same-bore comparison against every other series.

This series runs from a 10 mm to a 300 mm bore. The sub-library as a whole reaches 300 mm of bore, and the widest single bearing in it is a 6360, 620 mm across, in the 6300 series. This is one of the series that gets to that top bore.

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. The 6 series whose type has no bore are not rows here: they are indexed by the shaft they run on, and their chart is above.
