2026 manufacturer catalogue, not a universal fitment promise

Source: MAHLE/Clevite EB-20-26 engine-bearing catalogue. Entries retain the catalogue make section, application conditions and printed page. A make heading groups source applications; it is not proof that every engine listed was manufactured by that vehicle brand.

Numbers are Clevite references, not SKF/NTN cross-references. A set, a member shell and a separate thrust washer are different items. Unresolved or conflicting dimensions remain unavailable instead of being guessed.

Use the reference correctly

Identify before comparing

Keep engine code, production year, VIN qualifiers, bearing position and the existing shell markings. A 350, 1.8 or 4.6 label is not a unique engine identification.

Measure the actual assembly

Standard journal dimensions do not describe a worn or reground shaft. Verify the installed housing, required repair size and oil clearance with the engine-specific procedure.

Keep unresolved values unresolved

Empty dimensional fields can reflect set-only entries, incomplete source rows or conflicts. They do not mean zero clearance, and another entry's values are not a substitute.

Reference basis and limitations

This independent lookup reorganises factual entries from the 2026 MAHLE/Clevite engine-bearing catalogue. The original source fingerprint, extraction record and application block are retained privately. The catalogue source is not a guarantee of current stock, current vehicle approval or complete coverage of every engine. BearingScope does not sell these parts or provide a rebuild service.
