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.
TIMKEN 368A — individual cone dimensions
TIMKEN 368A is an individual tapered-roller cone: the inner ring, rollers and cage, not the complete cone-and-cup bearing. The manufacturer lists bore d = 50.8 mm (2 in) and inner-ring width B = 22.225 mm (0.8750 in).

Use the component number correctly
- The bore identifies the shaft-side nominal opening. B measures this cone only; it is not the assembled bearing width T. This single-cone record does not establish an outside diameter D or a matching cup.
- Preserve the full component number and its suffix. A shared prefix, similar ring size or a related-products suggestion does not approve a cone/cup combination or a cross-brand replacement.
- For a complete bearing, check both component markings and the manufacturer’s assembled d×D×T record. B+C is not a valid way to calculate T. A seal, axle rating, vehicle application and tightening procedure need their own evidence.
- Optional measurements with inconsistent printed metric and inch values are omitted from this supplement: Max Shaft Fillet Radius. Verify the manufacturer drawing before using these particular limits.

368 A 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. 15 recorded variants are listed. A dash means the value is missing, not zero.
Catalogue parameters for 368 A
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.
SKF 368 A — 16 recorded parameters
Single row tapered roller bearing, cone
Reference: SKF product catalogue; 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.

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.

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.
