Self-aligning ball bearings: types, dimensions & brand filters
Two ball rows and a spherical outer raceway accommodate limited shaft-to-housing misalignment.
On this page8 sections ⌄
What is this bearing type?
A self-aligning ball bearing has two rows of balls running against a common spherical outer-ring raceway. The inner assembly can align relative to the outer ring, accommodating limited shaft-to-housing misalignment.
| Part or design | What it does | What to verify |
|---|---|---|
| Two ball rows | Provide rolling contact in a self-aligning arrangement. | Do not confuse this with a double-row deep groove bearing. |
| Spherical outer raceway | Allows the inner assembly to swivel about the bearing centre. | The permitted angle still depends on the exact bearing and surrounding parts. |
| Bore and mounting | Cylindrical and tapered-bore arrangements require different mounting checks. | A sleeve is a separately matched mounting component. |

Variants that change the answer
Self-aligning ball and spherical roller bearings both address alignment, but use different rolling elements and load characteristics. The ball design is commonly considered for lighter radial duty; it is not a substitute for every heavy-load roller arrangement.
What the family name cannot tell you
Self-aligning does not mean unlimited shaft bending or unrestricted axial load. Seals, adjacent shoulders and the application can further restrict movement.
Identify the exact part before comparing
- Identify the full model and bore form.
- Check the source-specific permissible misalignment and axial load conditions.
- Retain sleeve and clearance information when comparing alternatives.

Look up real bearing dimensions
Choose a bearing structure, then enter the dimensions you know. You can leave unknown dimensions blank. The chart contains 29,253 catalogue records whose bore, outside diameter and width or height symbols have been checked against retained manufacturer properties. It is not a complete ISO standard or an interchange list.
Changing units converts entered values; it does not reinterpret 12.7 mm as 12.7 inches. Inch fractions such as 1/2 are accepted. A blank field means unknown, not zero.

Read the width symbol: B, T and H are not interchangeable labels. For a tapered pair use assembly T, not the cone width. Needle designs without an inner ring may use roller-set bore Fw instead of d and are outside this d/D chart. Matched sets, housings and loose cups/cones are also excluded. Open the full product to check drawings, ratings, seals, clearance and precision.
Snapshot 2026-10-02. Every row keeps its actual product link and source-reported units; missing or ambiguous geometry is withheld. Equal nominal size alone does not approve replacement. Inch display is a conversion, rounded to six decimals, not an inch-series classification.

Reference basis & data limits
Manufacturer terminology is retained in the product records. Technical reference basis: JTEKT Basic Bearing Knowledge (boundary dimensions, tolerance classes and lubrication); NSK Bearing ABCs (lubrication, designations and clearance); NTN technical FAQs (closure codes and component interchange); SKF rolling-bearing selection and maintenance references.
Selection workflows and catalogue grouping are BearingScope editorial aids. Verify the current drawing and application requirements before using a candidate. Missing database information is not converted into an assumed match.
