DIN 628 7200B Series Angular Contact Ball Bearings Specification
What DIN 628 fixes, what it deliberately leaves to another document, its equivalents, and the dimensional table.
DIN 628 is the German standard for angular contact ball bearings, restating the ISO 15 envelope for the type: part 1 the single row 7000 series, part 3 the double row 3200 and 3300 series, and part 4 the four-point contact QJ bearings.
Standard
DIN 628
Covers
Angular contact ball bearings
Does not fix
It fixes the envelope, not the contact angle variants a manufacturer offers, the preload class of a matched set, or the load rating — the first is a design choice, the second is agreed on the order and the third is ISO 281.
Equivalents
ISO 15 internationally; GB/T 292 for single row and GB/T 296 for double row in China.

Governing standards
ISO 15 / DIN 628-1 / GB/T 292
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.
7200B Series Angular Contact Ball Bearings manufactured to DIN 628 are tabulated below. The standard covers angular contact ball bearings — 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.
DIN 628 — Scope
DIN 628 is the German standard for angular contact ball bearings, restating the ISO 15 envelope for the type: part 1 the single row 7000 series, part 3 the double row 3200 and 3300 series, and part 4 the four-point contact QJ bearings.
What DIN 628 Does Not Fix
It fixes the envelope, not the contact angle variants a manufacturer offers, the preload class of a matched set, or the load rating — the first is a design choice, the second is agreed on the order and the third is ISO 281.
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 DIN 628
DIN 628 governs more than this one series. In this catalog it applies to:
DIN 628 remains in daily use in European mechanical engineering and on legacy drawings, and it is what many German-language datasheets cite. For a new design the ISO document is the better contractual reference, with the DIN number carried alongside it so that the drawing reads the same to everyone.
Other ways to specify the 7200B Series Angular Contact Ball Bearings
The same part is also governed by ISO 15, 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 DIN 628 specify?
DIN 628 is the German standard for angular contact ball bearings, restating the ISO 15 envelope for the type: part 1 the single row 7000 series, part 3 the double row 3200 and 3300 series, and part 4 the four-point contact QJ bearings.
What does DIN 628 not cover?
It fixes the envelope, not the contact angle variants a manufacturer offers, the preload class of a matched set, or the load rating — the first is a design choice, the second is agreed on the order and the third is ISO 281.
What is the equivalent of DIN 628?
ISO 15 internationally; GB/T 292 for single row and GB/T 296 for double row in China.
