25 mm bore / 52 mm outside diameter: what this result means
The shortlist fixes 25 mm bore / 52 mm outside diameter. Width is not specified; compare the recorded widths before choosing a model.
A bore is not the diameter of a loose precision ball. Complete bearings, inserts and other catalogue components can have different functions even where the recorded dimensions match. Keep the original product type visible when making a shortlist.
| Requested dimension | Millimetres | Inches | Selection meaning |
|---|---|---|---|
| Inside diameter d | 25 mm | 0.984252 in | Nominal catalogue value, not a shaft/housing fit tolerance |
| Outside diameter D | 52 mm | 2.047244 in | Nominal catalogue value, not a shaft/housing fit tolerance |
Inch conversions use 25.4 mm per inch and are displayed to six decimals. A converted metric dimension does not make a bearing an inch-series design.
Are your measurements in millimetres or inches?
The chart on this page uses millimetres. An unlabelled search such as 25 × 52 does not tell us which unit was measured. Choose the unit for those same numbers before opening a different catalogue lookup.
Inside diameter d: 25 mm; Outside diameter D: 52 mm
Search 25 × 52 mmConversion and reinterpretation are different
Same physical size, another unit: divide a dimension in millimetres by 25.4 to express it in inches. The bearing does not change.
The original numbers were inches: multiply those numbers by 25.4 to obtain the millimetre values used in the catalogue. For the numbers on this page, that means 635 × 1320.8 mm, not 25 × 52 mm.
One inch is exactly 25.4 millimetres. Displayed values are rounded to six decimals; rounding is not a manufacturing tolerance. Confirm the measured axes and the complete bearing construction before comparing models.
The unit choice updates the lookup immediately. The main chart below remains the millimetre size in this page heading. A catalogue search can have no recorded match; that means no match in the available data, not that the size cannot exist. A loose precision ball has one diameter and is not a complete bearing d×D×width measurement.

Snapshot 2026-10-01. Counts describe the available records, not every bearing made. The original product type is retained. Matched sets, units, flanges, sleeves and tapered assemblies require their own drawing; a recorded width is not automatically a single radial-ring width B. Unreported properties remain unknown. Matching dimensions do not approve substitution.
Keep these dimensions and choose a brand
Choosing a brand opens the existing live filters immediately with the dimensional conditions retained. These are catalogue candidates, not interchange approvals.
How to narrow the shortlist
- Confirm which dimension was measured: bore d, outside D or axial width. Do not use a flange diameter as the bearing outside diameter.
- Measure the remaining boundary dimensions and preserve the original marking. A single known diameter usually identifies several different models.
- Select the required construction, seals, clearance and precision in the live results. An unreported field is still unknown.
- Check the exact product drawing, load ratings, speed and mounting requirements before considering a replacement.
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.
