6307 — source-labelled NSK dimensions

Nominal dimensions from the NSK Bearing Replacement Guide, reference BRG/C/E/11.15. This is a historical catalogue reference, checked 2026-10-03; it is not a current product-availability list or an interchange approval. Each row preserves its complete printed designation.

Read d×D×B together. Equal outside dimensions do not prove equal seals, internal clearance, precision, load ratings, lubricant or speed limits. Those properties are not supplied by this dimensional table. A DU, DDU, Z, ZZ, VV, DD or other marking is kept as printed; missing suffix records are not created from a base model.

Exact model evidence

6307 dimensions and recorded technical data

The recorded 6307 base designation measures 35×80×21 mm (inside diameter d × outside diameter D × width B). This answer uses unsuffixed records from SKF, FAG, NSK, KOYO, NACHI, NTN. 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. 150 recorded variants are listed. A dash means the value is missing, not zero.

Measurement details

Read the original dimensions for 6307

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.

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.

Check the drawing before substituting

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.
