GB/T 276 6000-ZZ Series Shielded Ball Bearings Specification
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.

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.
For 6000-zz series shielded ball bearings, GB/T 276 is one of the controlling documents. The sections below describe its scope, the properties it does NOT decide and which standard does decide them, the equivalent designations, and the full size range.
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.

Catalog Products Governed by GB/T 276
GB/T 276 governs more than this one series. In this catalog it applies to:
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 6000-ZZ Series Shielded Ball Bearings
The same part is also governed by ISO 281 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
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).
What is the equivalent of GB/T 276?
ISO 15 and DIN 625-1 cover the same bearings with the same dimensions.
Does GB/T 276 mean two bearings are interchangeable?
Dimensionally, yes — that is what a boundary dimension standard is for, and a bearing of the same designation from any maker mounts in the same shaft and housing seat. Functionally, not necessarily: the load rating, the internal design, the cage, the clearance group and the speed limit are decided by the manufacturer and by other standards, and two bearings with the same number are not required to match on any of them.
Does GB/T 276 fix the load rating?
No. GB/T 276 does not set load ratings. Basic dynamic load ratings are calculated to the method of ISO 281 and are declared by the manufacturer; the static rating follows ISO 76.
