KLÜBER to Mobil Bearing Grease Cross-Reference Table
| KLÜBER Product | Equivalent Product | Compatibility & Notes |
| Kluberplex BEM 41-132 | Mobilux EP 2 | Both lithium, NLGI 2, mineral oil. Mobilux EP 2 has EP additives; Kluberplex BEM 41-132 is standard lithium. |
| Staburags NBU 12 | Mobilith SHC 100 | Different thickener (barium complex vs lithium complex). NBU 12 has MoS₂ and superior water washout resistance. |
| Staburags NBU 8 EP | Mobilith SHC 220 | NBU 8 EP has MoS₂ and barium complex water displacement — no direct Mobil equivalent for steel mill water spray. |
| Kluberspeed BF 72-22 | Mobil Polyrex EM | Both polyurea thickener. Kluberspeed optimized for low-noise electric motor bearings. Polyrex EM is widely used OEM fill. |
| ISOFLEX TOPAS NB 52 | Mobil Polyrex EM | Barium complex vs polyurea. ISOFLEX TOPAS rated to 2M DN vs Polyrex EM rated to 1M DN. |
| PETAMO GHY 441 | Mobilith SHC 220 | Both lithium complex. PETAMO rated to 180°C continuous vs SHC 220 rated to 150°C. |
| Klüberfood NH1 94-301 | Mobilgrease FM 222 | Both NSF H1 aluminum complex greases. KLÜBER adds ISO 21469 and Kosher/Halal certifications. |
| Kluberlub BE 71-501 | Mobilith SHC 100 | Bentonite vs lithium complex. BE 71-501 rated to 200°C vs SHC 100 rated to 150°C maximum. |

⚠ Important Disclaimer
This cross-reference is provided for informational purposes only. Equivalent does not mean identical — differences in thickener type, base oil viscosity, additive packages, and NLGI grade can affect performance. Always verify technical compatibility by consulting both manufacturers' datasheets and obtaining OEM approval before substituting lubricants. Contact KOEED for verified KLÜBER product recommendations matched to your specific application requirements.
> Tip
When cross-referencing, always verify: (1) thickener compatibility — mixing incompatible thickeners can cause grease to soften or harden, (2) base oil viscosity at operating temperature, (3) NLGI grade for proper consistency, (4) certification status (NSF H1, ISO 21469) for food-grade applications. If in doubt, contact KOEED for a verified recommendation.
Frequently Asked Questions
Q: Is Mobil Polyrex EM a direct replacement for ISOFLEX TOPAS NB 52?
They serve similar applications (high-speed bearings, electric motors) but are not identical. ISOFLEX TOPAS NB 52 uses barium complex thickener and is rated for DN values up to 2 million mm·rpm. Mobil Polyrex EM uses polyurea thickener and is rated for DN values up to approximately 1 million mm·rpm. For ultra-high-speed spindles above 1 million DN, ISOFLEX TOPAS is the recommended product.
Q: Does Mobil offer a barium complex grease?
No. Mobil's industrial grease thickener technologies are primarily lithium, lithium complex, polyurea, and aluminum complex. Barium complex thickener technology — which provides exceptional water displacement and mechanical stability — is unique to specialty manufacturers like KLÜBER. For applications where barium complex performance is specified, KLÜBER Staburags NBU and ISOFLEX TOPAS series have no direct Mobil equivalent.
