Certification Comparison
| Certification | KLÜBER | FUCHS | Significance |
| NSF H1 | ✓ (all food-grade products) | ✓ (all CASSIDA FM products) | Mandatory for incidental food contact |
| ISO 21469 | ✓ (Klüberfood NH1, PARALIQ) | ✓ (selected CASSIDA products) | Hygienic manufacturing certification |
| Kosher / Halal | ✓ (Klüberfood NH1 series) | ✓ (selected products) | Required for Kosher/Halal certified facilities |
| FDA 21 CFR 178.3570 | ✓ | ✓ | Approved ingredient list |
Key Product Matchups
| Application | KLÜBER | FUCHS | Note |
| Multi-purpose food-grade grease | Klüberfood NH1 94-301 | CASSIDA FM Grease EPS 2 | KLÜBER adds ISO 21469 + Kosher/Halal; both aluminum complex PAO |
| Food-grade gear oil | Klubersynth GH 6 series | CASSIDA FM Gear Oil | Comparable PAO gear oils; both NSF H1 |
| Food-grade hydraulic oil | Klubersynth CH 2 series | CASSIDA FM Hydraulic Oil | FUCHS has wider viscosity range in some markets |
| Food-grade chain oil | Klübersynth LI 44 series | CASSIDA FM Chain Oil | KLÜBER offers specialty high-temperature chain variants |
| Assembly paste | Kluberpaste UH1 96-402 | CASSIDA FM Paste | Products serve the same function; verify specific application |
Performance Considerations
KLÜBER food-grade products generally use a slightly higher percentage of synthetic base oils (PAO with higher VI) compared to FUCHS equivalents, which can result in extended service life and better high-temperature oxidation resistance. However, the practical difference in most food processing applications (operating at moderate temperatures and loads) may be marginal.
For facilities requiring Kosher and Halal certification in addition to NSF H1, KLÜBER's Klüberfood NH1 series has a more complete certification portfolio. For facilities primarily concerned with cost and local availability, FUCHS CASSIDA FM is often priced competitively and has broader distribution in certain European markets.
Frequently Asked Questions
Q: Can I mix KLÜBER and FUCHS food-grade greases in the same bearing?
Mixing should be avoided unless compatibility is verified. Both brands use aluminum complex thickeners in their primary food-grade greases, which are generally compatible with each other. However, differences in base oil viscosity and additive packages can alter the mixed grease's performance. If switching brands is necessary, purge the old grease completely and monitor bearing temperature during the transition period.
Q: Why is ISO 21469 certification important?
NSF H1 registration verifies the product formulation. ISO 21469 certification additionally verifies that the lubricant is manufactured, packaged, and labeled under hygienic conditions — addressing the risk of contamination during manufacturing rather than just the risk from the product itself. For food and pharmaceutical manufacturers subject to GFSI-benchmarked audits (BRC, SQF, FSSC 22000), ISO 21469 certified lubricants provide an additional layer of compliance assurance.
