Heidelberg Feeder Pulley F2.028.551/03

The most consistent market name for F2.028.551/03 is Heidelberg Feeder Pulley. The clearest exact-match source is a dedicated product page titled “Feeder Pulley F2.028.551/03”, while additional seller listings for the base family F2.028.551 describe it as a pulley belt, synchronous wheel, or drive pulley used in the feeder-head area. For catalog accuracy, the safest primary term is Heidelberg Feeder Pulley F2.028.551/03, with “drive pulley” and “synchronous wheel” used only as secondary search terms.

The exact part number researched is F2.028.551/03. During research, I also found the unsuffixed family number F2.028.551 used repeatedly in aftermarket listings. Those sources appear to describe the same pulley family, but I did not find strong evidence proving that F2.028.551 and F2.028.551/03 are always interchangeable across every machine setup. Because the suffix may indicate a revision or machine-specific variation, the safest sales wording is to keep /03 clearly in the title, meta description, short description, and long description.

For the industry term, the best-supported wording is feeder pulley. Aftermarket sources also use toothed pulley, belt pulley, and synchronous wheel, and some provide dimensions and tooth count. Those secondary terms are useful for SEO, but feeder pulley is the clearest term tied directly to the exact F2.028.551/03 listing.

Documented Compatibility

The strongest model link I found for the exact suffix F2.028.551/03 is SM 52, based on an exact-match seller listing and an Alibaba listing that specifically references Heidelberg SM52 Printing Machine. I also found broader aftermarket references for the unsuffixed F2.028.551 family that mention SM 102, CD 102, and XL 105, but those sources refer to the base code rather than the exact /03 suffix. Because of that difference, I would not present SM 102, CD 102, or XL 105 as confirmed compatibility for F2.028.551/03 without technical confirmation.
