SET4 bearing dimensions & suffix variants

Look up recorded dimensions for designations beginning with SET4. The table retains complete manufacturer designations so special suffixes and different dimensional variants remain visible.

On this page6 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.

TIMKEN SET4 — bearing pairs and set identification

TIMKEN SET4 identifies a bearing package. The 2002 manufacturer listing pairs cone L44649 with cup L44610. Keep both full markings when checking the assembly.

Complete bearing dimensions by exact pair

These TS single-row tapered-roller combinations are reproduced as factual measurements from the 2002 reference. Dimensions are not a fitment approval or a current availability claim. Each cell keeps both published units.

What to confirm before using this reference

  • d is the cone bore, D is the cup outside diameter and T is the complete bearing width for the exact pair. B and C measure the separate rings; do not add B and C to calculate T.
  • The dimensional table is a historical identification reference from the 2002 Timken Bearing Specification Guide, not a current engineering drawing. Printed metric and inch values are retained, including their original rounding. Check the current drawing before specifying fits or machining.
  • A component may appear with several mating numbers. A match here documents that exact Timken combination; it does not approve other suffixes, mixed-brand rings, a vehicle application or a substitute with similar dimensions.
  • A cone-and-cup set is not automatically a complete wheel-end repair kit. Seal numbers, collars, spacers and quantities must be confirmed separately unless the specific set note below explicitly lists them.
  • For replacement work, inspect and replace the mating cup and cone together as specified for the assembly. Retaining a worn ring or mixing manufacturer geometries can change the contact pattern even when nominal diameters match.
  • An axle tightening torque, preload or endplay target cannot be derived from these dimensions. Use the procedure for the identified hub or machine, including any pre-adjusted system restrictions.

Manufacturer references: Timken Bearing Specification Guide, Order 7534 (2002, archived distributor-hosted copy); Timken MileMate set chart, Order 5523 (May 2024), where listed; Timken cup-and-cone replacement guidance, Order 10832 (2016).

SET4 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. 2 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.

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.
