Angular Contact Ball Bearings · ISO 15 / DIN 628-1 / GB/T 292
ISO 15 7000C Series Angular Contact 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.

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.

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.
ISO 15 covers boundary dimensions of radial rolling bearings. This page sets out what the standard fixes for 7000c series angular contact ball bearings, what it deliberately leaves to other documents, its national equivalents, and the dimensional table supplied against 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.

Catalog Products Governed by ISO 15
ISO 15 governs more than this one series. In this catalog it applies to:
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 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.
Does ISO 15 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 ISO 15 fix the load rating?
No. ISO 15 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.
