Specification summary of GB T 292 as applied to angular contact ball bearing: the dimensions the standard fixes, the full size range supplied, and the related designations commonly cross-referenced.
GB T 292 — Scope
The table below lists the dimensions catalogued for angular contact ball bearing — iso / din (series 109) under GB T 292. The scope of GB T 292 itself is not summarised here — where a figure matters, confirm it against the published document.
Tolerance & Product Grades
Product grade is a concept from dimensional fastener standards and does not apply to GB T 292. Tolerances for this part are the limits shown against each dimension in the table.

Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Angular Contact Ball Bearing — ISO / DIN (Series 109) page.
Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
Companion Standards
A complete specification for angular contact ball bearing — iso / din (series 109) normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. GB T 292 is one of them, not all of them.
Custom manufacturing · Made to drawing
Need a bearing & bushing to this standard in a non-standard size?
Parts built to GB T 292 are already in the catalog, so a special is usually a variation on existing tooling rather than a new design — which is what keeps the cost down.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
