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.
33118 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. 7 recorded variants are listed. A dash means the value is missing, not zero.

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.

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.
Minimum and maximum mounting dimensions are limits, not nominal bearing dimensions. Check shaft/housing shoulders and fillets against the current drawing before designing a seat.

Metric and inch measurements below are the values published together in this dated manufacturer record. Their displayed rounding is retained; the inch column does not turn a metric design into an inch-series design.
This assembly is identified by cone X33118M and cup Y33118M. T is the assembled width; B and C are the separate ring widths. A loose cone, a loose cup and the complete assembly are not the same item.
Shaft and housing backing-shoulder dimensions, maximum fillet radii and signed offsets answer different installation questions. Preserve the named face, limit and sign; they are not additional bearing outside diameters or nominal widths.
This factual extract is a dimensional reference, not an OEM fitment statement, a replacement approval or a downloadable CAD model.

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.

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.
