683 bearing dimensions & suffix variants
Look up recorded dimensions for designations beginning with 683. The table retains complete manufacturer designations so special suffixes and different dimensional variants remain visible.

Find by measured dimensions
Enter bore d, outside diameter D and width B. Use decimals or inch fractions such as 1/2 or 1 1/4.
683 dimensions and recorded technical data
The recorded 683 base designation measures 3×7×2 mm (inside diameter d × outside diameter D × width B). This answer uses unsuffixed records from KOYO. It does not assign the same dimensions or operating ratings to every suffix.
The numeric series boundary is preserved: a longer number is not included merely because its first digits match. 22 recorded variants are listed. A dash means the value is missing, not zero.
Read the original dimensions for 683
Boundary size alone does not describe every ring, shoulder or assembled unit. These tables retain the recorded manufacturer labels, symbols, units and limits for each complete marking. Expand a record to check its detailed measurements.
Important: an approximate value, a minimum or a maximum keeps that qualifier. These reference extracts are not CAD drawings, fit recommendations or replacement approvals.
KOYO 683/672 — 5 dimension fields
Tapered roller bearing. Source: JTEKT / Koyo product catalogue; recorded snapshot 2026-09-02.
For a tapered bearing, total assembly width T, inner-ring width B and outer-ring width C are different measurements. Keep the complete cup/cone or matched assembly designation; do not replace T with B when checking available axial space.

Catalogue parameters for 683
Choose the complete brand and marking before reading a value. These source-labelled records add dimensions, construction and engineering properties where they were recorded; a shared model number does not establish interchangeability.
Units, ranges and minimum/maximum qualifiers are retained. The data is a dated catalogue reference, not a certified drawing, a complete current specification or an operating approval.
KOYO 683/672 — 23 recorded parameters
Tapered roller bearing
Reference: JTEKT / Koyo catalogue; source snapshot 2026-09-02.
Keep total assembly width distinct from inner- and outer-ring widths. The same nominal bore does not establish a matching cup/cone set.
Values shown are retained from the recorded source. Zero boundary dimensions and zero load ratings from incomplete legacy feeds are withheld rather than presented as usable specifications.

How to compare these values
- Use the displayed dimension names and original symbols. Housing length L, height H2 and flange width are not bearing outside diameter D. A catalogue width with an unverified symbol must not be assumed to be inner-ring width B or assembly width T. Open the product record for mounting dimensions and geometry.
- Inch values are calculated from the recorded millimetres using 25.4 mm per inch, rounded to six decimal places. They do not change a metric bearing into an inch-series bearing. Gram values are converted from the recorded mass in kilograms.
- C and C0 describe different rating conditions. They are not a single safe working-load limit and cannot replace an application load calculation.
- Reference and limiting speeds are separate catalogue values. The source grease/oil context is shown where recorded. Lubricant, seals, loads, fit, clearance and cooling affect the usable operating speed.
- A common base number does not prove equivalent seals, clearance, precision, material or interchangeability. Open the full designation for these fields.
Related prefix matches — other model numbers may appear
These discovery results can contain a longer number or a different component. They are not specifications for the requested exact model. Open the complete product to inspect its original geometry.

Nominal dimensions are not shaft-fit tolerances. Different variants can add grooves, flanges, wider rings or assembly components. When the table has different dimensions, the complete designation—not the shared prefix—controls.
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.
