How to Read and Decode Hauni/Molins/GD/Focke Spare Part Numbers
Every OEM in the tobacco machinery industry uses a different spare part numbering system. Understanding these codes helps maintenance engineers identify correct parts faster, avoid ordering errors, and cross-reference between OEM and aftermarket suppliers. This guide decodes the numbering conventions used by the four major tobacco machinery manufacturers.
Hauni Part Number System
Hauni (now Körber Technologies) uses a numeric system with embedded meaning about the part's function and material.
Structure: XX-YYYY-ZZZ
| Segment | Example | Meaning |
|---|---|---|
| Machine prefix (2 digits) | 70- | Machine series (70 = PROTOS 70, 80 = PROTOS 80, 90 = PROTOS V90) |
| Functional group (3-4 digits) | 210- | Assembly group (200 series = garniture section, 300 series = cutting head) |
| Item variant (2-3 digits) | 123 | Specific component within the assembly group |
Examples decoded:
- 80-210-123: PROTOS 80, garniture section component #123
- 70-315-456: PROTOS 70, cutting head component #456
- KT2-205-789: KT2 tobacco cutter, knife assembly component #789
Important: Hauni part numbers with the same numeric suffix but different machine prefix often indicate the same part design. For example, 80-210-123 and 70-210-123 may be interchangeable. However, always verify dimensional compatibility before substituting.
Molins Part Number System
Molins (acquired by Körber Technologies, now part of the Hauni brand portfolio) uses an alpha-numeric system with letter prefixes indicating the material or manufacturing process.
Structure: [Prefix][Number]
| Prefix | Meaning | Example |
|---|---|---|
| MCB- | Molins Consumable Belt | MCB-0012 (vacuum belt) |
| MCK- | Molins Cutting Knife | MCK-0423 (cutting knife assembly) |
| MCP- | Molins Cast Part | MCP-0881 (cast iron guide) |
| MCS- | Molins Steel Fabrication | MCS-1502 (steel bracket) |
| MFT- | Molins Filtration | MFT-0021 (filter cartridge) |
| MSR- | Molins Seal/Ring | MSR-0033 (lip seal) |
Numeric sequence: The number following the prefix is typically sequential — the first digit sometimes indicates the machine generation (0 = MARK 8, 1 = MARK 9, 2 = MARK 9N), but this convention is not consistently applied.
G.D Part Number System
G.D SpA uses a structured system that identifies the machine family, assembly, and component variant.
Structure: GD-[MachineCode]-[Assembly][Variant]
| Segment | Example | Meaning |
|---|---|---|
| Brand prefix | GD- | G.D brand identifier |
| Machine code | X2- | X2 = X2 packer, X3 = X3 packer, X6 = X6 packer |
| Assembly code (2 letters) | CF- | CF = carton former, PP = pusher paddle, HM = hot melt, TF = tucker finger, KB = knockout bar |
| Variant number (3 digits) | 100 | Specific variant within the assembly category |
Decoded examples:
- GD-X2-CF-100: G.D X2 carton former blade, variant 100
- GD-X6-PP-210: G.D X6 pusher paddle assembly, variant 210
- GD-HM-005: G.D hot melt glue nozzle (shared across machine families — no machine code)
G.D also uses an older numbering system for legacy parts (pre-2000), typically formatted as a 6-digit number without letters. These parts should be cross-referenced by dimension rather than number alone.
Focke Part Number System
Focke & Co. uses a machine-family prefix followed by a functional code and a sequential component number.
Structure: FC-[MachineCode]-[Function][Number]
| Segment | Example | Meaning |
|---|---|---|
| Brand prefix | FC- | Focke & Co. identifier |
| Machine code | 701- | 701 = Focke 701, 703 = Focke 703, 750 = Focke 750 |
| Functional code (2 letters) | GR- | GR = guide rail, FFR = foil feed roller, UJ = upper jaw, LJ = lower jaw |
| Component number (3 digits) | 100 | Sequential component identifier |
Decoded examples:
- FC-701-GR-100: Focke 701 guide rail assembly
- FC-703-UJ-200: Focke 703 upper sealing jaw
- FC-750-FCB-100: Focke 750 film cutter blade
For parts shared across multiple Focke machine models, the machine code is replaced with a generic code (e.g., FC-GEN-). These parts are typically interchangeable between 700 series machines.
Cross-Reference Tips
- Use the original part number — when possible, order using the OEM number stamped on the existing part
- Include machine serial number — production date can affect part variant compatibility
- Typical cross-reference fields: OEM part number, ZTLibre part number, material spec, dimensions
- Always verify physically — even when part numbers match, manufacturing revisions can affect fit
ZTLibre Cross-Reference Database
ZTLibre maintains a comprehensive cross-reference database covering over 10,000 OEM part numbers across all four manufacturers. Our team can typically identify an equivalent part within 24 hours when provided with any of the following: OEM part number, machine model and position, or a photograph of the existing part with dimensions. Contact our parts identification service for assistance.
Send us your OEM part number list and we will return a ZTLibre equivalent catalog with pricing and lead time within one business day. Our cross-reference accuracy rate exceeds 99.5% based on 5000+ verified matches.
Revision and Version Tracking
Part numbers alone do not always indicate the correct version. OEMs frequently revise parts to improve performance, address failure modes, or accommodate material changes. Understanding revision tracking systems prevents ordering out-of-date components.
- Hauni revisions: indicated by dash-number suffixes. For example, 80-210-123-01 vs 80-210-123-02. Higher dash numbers indicate newer revisions. Always order the highest available revision unless specifically advised by the manufacturer.
- G.D revisions: incorporated into the variant number. GD-X2-CF-100 and GD-X2-CF-101 are different variants, not necessarily revisions. G.D uses revision letters in the production date code, which is printed separately from the part number.
- Molins revisions: indicated by letter suffixes (MCB-0012-A vs MCB-0012-B). Revision A is the original design; subsequent letters indicate changes. Not all parts progress through the full alphabet.
- Focke revisions: indicated by hyphen-number suffix (FC-701-GR-100-1 vs FC-701-GR-100-2). Focke uses a controlled revision system with full change documentation.
Serial Number Block Identification
Many OEM part numbers include serial number blocks that identify which machine serial numbers a particular part variant fits. This is especially common with G.D and Focke parts where design changes were implemented mid-production.
- G.D X6 machines: serial numbers before #4862 use X6-CF-100-01, serial numbers #4862 and later use X6-CF-100-02
- Focke 750 machines: serial numbers in the range 1000-1500 use one variant, 1501-2000 use an updated variant with modified bolt pattern
- Hauni PROTOS 80 machines: serial number prefix indicates the factory of origin, which can affect the part number system used
Cross-Reference Between OEM and Aftermarket Systems
Aftermarket suppliers use their own part numbering systems, but most maintain cross-reference databases that map their numbers to OEM numbers. At ZTLibre, our part number format follows the ZT-[Machine Code]-[Function]-[Number] convention. For example, ZT-P80-GK-300 corresponds to the Hauni P80-GK-300 garniture knife. Our cross-reference database covers over 10,000 OEM numbers across Hauni, Molins, G.D, and Focke brands.
When contacting us for part identification, provide the following information for the most accurate cross-reference: OEM part number stamped on the existing part (or a clear photograph), machine brand and exact model number, machine serial number (found on the nameplate), and a photograph of the part with a ruler for scale if the part number is illegible.
