ISO 104 Thrust Bearing Specification

Dimensional table, tolerance classes and the DIN / ISO / ASME parts that supersede or match this standard.

ISO 104 specifies the dimensions and tolerances for thrust bearing. The full dimensional table is reproduced below, followed by the DIN, ISO and ASME parts that match or supersede it.

Governing standards

Equivalence between national standards is dimensional, not always metallurgical. Check the property class separately when substituting.

ISO 104 Thrust Bearing Specification reference image

Specification summary of ISO 104 as applied to thrust bearing: the dimensions the standard fixes, the full size range supplied, and the related designations commonly cross-referenced.

ISO 104 — Scope

The table below lists the dimensions catalogued for thrust bearing — iso / din (series 110) under ISO 104. The scope of ISO 104 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 ISO 104. 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 Thrust Bearing — ISO / DIN (Series 110) 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 thrust bearing — iso / din (series 110) normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. ISO 104 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 ISO 104 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.

Technical Drawing

Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

Applications & Industries

The sectors that buy Thrust Bearing, and the duty each one buys them for. Stocked from 10 to 80 (bore diameter).

Industries that specify Thrust Bearing

  • Conveyors & handling Rollers, idlers and drive shafts.
  • Pumps, fans & motors Shaft support with defined life and lubrication.
  • Power transmission Supporting rotating shafts under radial and axial load.

Typical applications

  • carrying radial and axial load in a housing
  • supporting a rotating shaft with low friction

Inside the plant

Manufactured in our own plant

This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.

  1. Wire rod feeding into a cold heading machine
    01

    Cold heading

    Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.

    Head dimensions and under-head radius checked at set-up and per shift.

  2. Thread rolling machine producing bolt threads
    02

    Thread rolling

    Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.

    Go / no-go ring gauges to ISO 965 tolerance class 6g.

  3. Baskets of bolts staged for heat treatment
    03

    Heat treatment

    Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.

    Core hardness and tensile tested per lot to ISO 898-1.

  4. Zinc plated bolts in a treatment basket
    04

    Surface treatment

    Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.

    Coating thickness and neutral salt spray hours to ISO 9227.

Frequently Asked Questions

Which edition of ISO 104 does this table follow?

The table reproduces the dimensions we supply thrust bearing — iso / din (series 110) to. We do not publish an edition year against it, so where the edition is contractually significant, cite the edition you require on the enquiry and we will confirm it against the table before quoting.

Can I substitute ISO 104 for the corresponding DIN standard on a drawing?

On modern drawings the ISO standard is the master reference; the older DIN equivalent is a cross-reference. For most dimensional purposes the parts are interchangeable, but check tolerance grades and the head height — these are the most common points of divergence.

How do I request a quotation?

Use the technical drawing on this page to pick the exact configuration, then submit it with the quote form. We respond within one business day.
