ISO 15 600 and 6900 Extra Small Series Miniature Ball Bearings Specification
What ISO 15 fixes, what it deliberately leaves to another document, its equivalents, and the dimensional table.
ISO 15 fixes the boundary dimensions of metric radial rolling bearings: the bore d, the outside diameter D, the width B and the limiting corner radius r, arranged in diameter and width series so that a bore of 20 mm exists in several standard envelopes (6004, 6204, 6304, 6404). It is the reason a 6204 from any manufacturer drops into the same housing.

Covers
Boundary dimensions of radial rolling bearings
Does not fix
It says nothing about how much load the bearing carries, how fast it may run, how accurately it is made or how much clearance it has. Load ratings are calculated to ISO 281, running accuracy is ISO 492 and radial internal clearance is ISO 5753-1.
Equivalents
DIN 616 restates the dimension plan nationally, with the individual bearing types in DIN 625, DIN 628, DIN 630, DIN 635 and DIN 5412; GB/T 273.3 carries the same plan in China.
Product
600 and 6900 Extra Small Series Miniature Ball Bearings
Governing standards
ISO 15 / DIN 625-1 / GB/T 276
Equivalence between the ISO, DIN and GB/T documents is dimensional: a bearing made to either mounts in the same seat. It is not an equivalence of load rating, tolerance class or internal clearance, each of which is fixed by a separate standard and declared separately.
Specification summary of ISO 15 (boundary dimensions of radial rolling bearings) as it applies to 600 and 6900 extra small series miniature ball bearings: what the document fixes, where its scope ends, the ISO, DIN and GB/T equivalents, and the dimensions supplied to it.
ISO 15 — Scope
ISO 15 fixes the boundary dimensions of metric radial rolling bearings: the bore d, the outside diameter D, the width B and the limiting corner radius r, arranged in diameter and width series so that a bore of 20 mm exists in several standard envelopes (6004, 6204, 6304, 6404). It is the reason a 6204 from any manufacturer drops into the same housing.
What ISO 15 Does Not Fix
It says nothing about how much load the bearing carries, how fast it may run, how accurately it is made or how much clearance it has. Load ratings are calculated to ISO 281, running accuracy is ISO 492 and radial internal clearance is ISO 5753-1.
This division of labour is the thing to carry away from any bearing standard. A boundary dimension standard makes bearings interchangeable; it does not make them equivalent. Two bearings of the same designation from different makers mount in the same seat and are not required to have the same load rating, the same internal design, the same cage or the same speed limit.

Other ways to specify the 600 and 6900 Extra Small Series Miniature Ball Bearings
The same part is also governed by GB/T 276 and ISO 5753-1, and where two standards cover one dimension they agree — the numbers are the same, the document is not.
Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the designation snaps the other fields to that size's standard values; you can then override any individual value.
Sends the selected values to the quote form below.
Our facility
Held in production, not just on paper
The tolerances above are decided on the grinding and superfinishing lines in our own plant, and gauged on every ring rather than on a sample. A dimension is only worth quoting if it survives the process that produces it.

Frequently Asked Questions
Can I cite the GB/T number instead of the ISO one?
For the boundary dimensions, yes — the GB/T standards restate the ISO dimension plan and a part made to either mounts in the same seat. The safest drawing note gives both, because it stays legible if the supply moves between a Chinese, a European and an international manufacturer.
What does ISO 15 specify?
ISO 15 fixes the boundary dimensions of metric radial rolling bearings: the bore d, the outside diameter D, the width B and the limiting corner radius r, arranged in diameter and width series so that a bore of 20 mm exists in several standard envelopes (6004, 6204, 6304, 6404). It is the reason a 6204 from any manufacturer drops into the same housing.
What does ISO 15 not cover?
It says nothing about how much load the bearing carries, how fast it may run, how accurately it is made or how much clearance it has. Load ratings are calculated to ISO 281, running accuracy is ISO 492 and radial internal clearance is ISO 5753-1.
What is the equivalent of ISO 15?
DIN 616 restates the dimension plan nationally, with the individual bearing types in DIN 625, DIN 628, DIN 630, DIN 635 and DIN 5412; GB/T 273.3 carries the same plan in China.
