What GB/T 276 fixes, what it deliberately leaves to another document, its equivalents, and the dimensional table.
GB/T 276 is the Chinese national standard for the boundary dimensions of single row deep groove ball bearings, identical in the dimensions it fixes to ISO 15 for this bearing type. A 6204 supplied to GB/T 276 mounts in the same seat as one supplied to ISO 15 or DIN 625-1.

Does not fix
It fixes dimensions. Load ratings follow GB/T 6391 (equivalent to ISO 281), tolerances GB/T 307.1 (ISO 492) and internal clearance GB/T 4604.1 (ISO 5753-1).
Equivalents
ISO 15 and DIN 625-1 cover the same bearings with the same dimensions.

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.
S6800 Series Stainless Steel Thin Section Ball Bearings manufactured to GB/T 276 are tabulated below. The standard covers deep groove ball bearings, boundary dimensions — and reading it as though it covered anything else is the most common mistake made with a bearing standard, so the boundary of its scope is set out first.
GB/T 276 — Scope
GB/T 276 is the Chinese national standard for the boundary dimensions of single row deep groove ball bearings, identical in the dimensions it fixes to ISO 15 for this bearing type. A 6204 supplied to GB/T 276 mounts in the same seat as one supplied to ISO 15 or DIN 625-1.
What GB/T 276 Does Not Fix
It fixes dimensions. Load ratings follow GB/T 6391 (equivalent to ISO 281), tolerances GB/T 307.1 (ISO 492) and internal clearance GB/T 4604.1 (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.

National Equivalents
ISO 15 and DIN 625-1 cover the same bearings with the same dimensions.
This product is supplied against ISO 15 / DIN 625-1 / GB/T 276, which names the documents it is made to.
When to Cite GB/T 276
GB/T 276 is the Chinese national standard and is what a Chinese manufacturer works to, so citing it removes any ambiguity on an order placed in China. It restates the same dimensions as its ISO parent, so quoting both — the GB/T number and the ISO number — is the practice that survives a supply change.
Other ways to specify the S6800 Series Stainless Steel Thin Section Ball Bearings
The same part is also governed by ISO 15 and DIN 625, 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.

The numbers come off our own machines
Every ring is gauged for bore and outside diameter, every assembly for radial internal clearance to ISO 5753-1, and every finished bearing for vibration. That is why the values on this page are quotable rather than indicative.

Frequently Asked Questions
Which edition of GB/T 276 does this table follow?
The table reproduces the dimensions we supply s6800 series stainless steel thin section ball bearings to. We do not publish an edition year against it, so where the edition is contractually significant, cite the edition you require on the enquiry and we will confirm it against the table before quoting.
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 GB/T 276 specify?
GB/T 276 is the Chinese national standard for the boundary dimensions of single row deep groove ball bearings, identical in the dimensions it fixes to ISO 15 for this bearing type. A 6204 supplied to GB/T 276 mounts in the same seat as one supplied to ISO 15 or DIN 625-1.
What does GB/T 276 not cover?
It fixes dimensions. Load ratings follow GB/T 6391 (equivalent to ISO 281), tolerances GB/T 307.1 (ISO 492) and internal clearance GB/T 4604.1 (ISO 5753-1).
