HK3026 bearing dimensions & suffix variants

Look up recorded dimensions for designations beginning with HK3026. The table retains complete manufacturer designations so special suffixes and different dimensional variants remain visible.

On this page5 sections

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.

For tapered assemblies use total width T; for units or flanged bearings also check the mounting drawing.

Exact model evidence

HK3026 dimensions and recorded technical data

Use the named dimensions for each complete record below. A generic d×D×B answer is not asserted where the base record is missing, dimension symbols are unverified, or the product uses a different geometry such as a housing or thrust assembly. Suffix records are not substituted for a missing base specification.

The numeric series boundary is preserved: a longer number is not included merely because its first digits match. 5 recorded variants are listed. A dash means the value is missing, not zero.

Exact designation reference

Catalogue parameters for HK3026

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.

INA HK3026 — 13 recorded parameters

Drawn cup needle roller bearing open end

Reference: Schaeffler medias — INA; source snapshot 2026-09-02.

This designation identifies a tapered-bearing component. A cone or cup alone is not the assembled bearing; use the documented pairing and total assembly width before comparing an interchange.

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.

KOYO HK3026 — 11 recorded parameters

Needle roller bearing

Reference: JTEKT / Koyo catalogue; source snapshot 2026-09-02.

Under-roller diameter Fw, shaft raceway dimensions and an inner-ring bore are not interchangeable labels. Check whether an inner ring is included in the exact construction.

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.

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.
