H315 bearing dimensions & suffix variants
Look up recorded dimensions for designations beginning with H315. The table retains complete manufacturer designations so special suffixes and different dimensional variants remain visible.

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.
H315 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. 6 recorded variants are listed. A dash means the value is missing, not zero.
Catalogue parameters for H315
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.
FAG H315 — 14 recorded parameters
Adapter sleeve
Reference: Schaeffler medias — FAG; source snapshot 2026-09-02.
FAG H315 connects two different nominal diameters: the sleeve bore/shaft-side diameter is 65 mm, while the bearing-side small taper diameter is 75 mm. Do not use the bearing-side number as the cylindrical shaft diameter.
The sleeve length is 55 mm; lock-nut outside diameter is 98 mm; the source gives 14.5 mm for the nut-and-locking arrangement. These dimensions belong to different parts, not to a bearing d×D×B envelope.
Calculated inch reference (shaft-side diameter × bearing-side diameter × sleeve length): 2.559055 × 2.952756 × 2.165354 in. This converts the recorded millimetres using exactly 25.4 mm/in and rounds to six decimals; it does not change the nominal series or supply machining tolerances.
Match the full sleeve, bearing bore form, nut and locking arrangement. The listed sleeve dimensions alone do not specify drive-up distance, final internal clearance or an approved tightening procedure.
Read the complete suffix and recorded construction. Similar dimensions do not prove identical seals, clearance, precision or material.
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.

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.
