Full title and description
ISO 104:1979 — Rolling bearings — Thrust bearings with flat back faces — Boundary dimensions. This entry refers to the 1979 International Standard and the Russian-language PDF edition that has been circulated by national sellers and archives for historical/reference use.
Abstract
This standard specifies the boundary (envelope) dimensions for thrust (axial) rolling bearings having flat back faces, giving dimensional series, minimum chamfer requirements and related limits for shaft and housing washers. ISO 104:1979 is a short technical specification (12 pages) that was later revised and withdrawn in favour of subsequent editions.

Facts above are taken from ISO bibliographic records and commercial standard catalogs for the 1979 edition.
Scope
ISO 104:1979 defines the boundary dimensions (external and bore related limits) for thrust bearings with flat back faces; it replaces earlier ISO/R 104 nominal chamfer values with minimum chamfer dimensions and supplies maximum outside diameters for shaft washers and minimum bore diameters for housing washers for several dimension series. The scope is limited to dimensional envelope data (not materials, tolerances beyond those necessary for interchangeability, or performance requirements).
Key topics and requirements
- Standardized envelope (boundary) dimensions for thrust bearings with flat back faces.
- Minimum chamfer dimensions replacing previous nominal chamfer values.
- Maximum outside diameters for shaft washers and minimum bore diameters for housing washers for specified series.
- Series and size tables to ensure interchangeability between manufacturers.
- Reference to prior recommendation ISO/R 104 and later revisions that update the general plan.
Typical use and users
Used by bearing design engineers, mechanical designers, bearing manufacturers, procurement specialists and standards librarians for ensuring dimensional interchangeability of thrust bearings and their washers. Also consulted by maintenance engineers, technical trainers and legacy product teams dealing with equipment designed to older standards.
Related standards
ISO 104:1979 was later revised; see ISO 104:1994 and subsequent consolidated editions (ISO 104:2015 as listed in ISO catalogs) which update and replace the 1979 edition. It is also related to earlier ISO/R 104 (1966) recommendation and other ISO series covering rolling bearing dimensional plans.

FAQ
Q: What is this standard?
A: ISO 104:1979 is an international standard that specifies the boundary (envelope) dimensions for thrust (axial) rolling bearings with flat back faces.
Q: What does it cover?
A: It covers dimensional series, minimum chamfer dimensions, and limits for shaft and housing washers so that thrust bearings made by different manufacturers are dimensionally interchangeable; it does not specify materials or performance tests.
Q: Who typically uses it?
A: Bearing designers and manufacturers, mechanical engineers, procurement and maintenance personnel, and standards/technical libraries consulting historical or legacy-product specifications.
Q: Is it current or superseded?
A: ISO 104:1979 has been withdrawn and superseded by later editions (notably ISO 104:1994 and later consolidated editions such as ISO 104:2015 listed in ISO records). For current design work you should reference the latest active edition.
Q: Is it part of a series?
A: Yes — it follows the general plan for bearing boundary dimensions originating from ISO/R 104 and fits within the family of ISO standards for rolling bearings maintained by ISO/TC 4. Subsequent parts and revisions carry the same base number with different edition years.
Q: What are the key keywords?
A: Thrust bearings; rolling bearings; boundary dimensions; envelope; chamfer; shaft washer; housing washer; ISO 104; interchangeability.
