32018 bearing dimensions & suffix variants

Look up recorded dimensions for designations beginning with 32018. 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

32018 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. 17 recorded variants are listed. A dash means the value is missing, not zero.

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.
