Heidelberg Toothed Belt Pulley F2.028.522/02

The safest technical name for F2.028.522/02 is Pulley for Toothed Belt or Toothed Belt Pulley. That wording appears in an XL 105 parts list and is repeated in supplier listings for the same Heidelberg part family, making it the best term for SEO and technical clarity.

The strongest documented machine compatibility is Heidelberg XL 105. An XL 105 parts list explicitly shows F2.028.522 /02 – Pulley for toothed belt, which is the clearest evidence found for the exact suffix version requested.

Several aftermarket suppliers also list the base reference F2.028.522 for SM102, CD102, CX102, XL105, and XL106. Because those broader machine claims come from reseller and marketplace sources rather than a Heidelberg-origin parts book for the exact suffix, they should be treated as secondary compatibility and verified against the installed part before ordering.

• Heidelberg SM 102

  These models appear in aftermarket listings for the base number F2.028.522, but I did not find equally strong documentation tying all of them to the exact suffix /02.

Part number verification

Documented variation
