KLÜBER to Shell Industrial & Synthetic Gear Oil Cross-Reference Table
| KLÜBER Product | Equivalent Product | Compatibility & Notes |
| Klubersynth GEM 4-220 N | Shell Omala S4 GX 220 | Both PAO synthetic gear oils with EP additives for industrial gearboxes. Verify OEM approvals. |
| Klubersynth GEM 4-320 N | Shell Omala S4 GX 320 | Both PAO synthetic, ISO VG 320. Klubersynth GEM 4 N has wind turbine-specific micropitting protection. |
| Klubersynth GEM 4-460 N | Shell Omala S4 GX 460 | Both PAO synthetic, ISO VG 460. For cement mill and heavy industrial drives. |
| Klubersynth GEM 4-680 N | Shell Omala S4 GX 680 | Both PAO synthetic, high viscosity for heavily loaded, low-speed gear drives. |
| Klubersynth GH 6-220 | Shell Omala S4 GX 220 | Both PAO synthetic. GH 6 is a general industrial gear oil. Omala S4 GX has additional EP chemistry. |
| Klubersynth GH 6-460 | Shell Omala S4 GX 460 | Comparable PAO synthetic ISO VG 460 gear oils. Verify specific EP and micropitting requirements. |
| Klubersynth LI 44-22 | Shell Gadus S2 OG 40 | Chain oils with adhesive properties. Verify viscosity for the specific chain type and operating temperature. |
| Klubersynth CH 2-100 | Shell Naturelle HF-E 46 | Both NSF H1 food-grade hydraulic oils. Different viscosity grades — verify system requirements. |

⚠ 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 Shell Omala S4 GX a direct equivalent to Klubersynth GEM?
They are both PAO-based synthetic industrial gear oils and are generally comparable in specification. However, the additive packages differ — Klubersynth GEM 4 N series was specifically developed with enhanced anti-micropitting additives per FVA 54/7 for wind turbine gearboxes. For standard industrial gearboxes, both products provide excellent performance. For wind turbine gearboxes, verify that the specific OEM approval list includes the selected product.
Q: Can I switch from Klubersynth GEM to Shell Omala without flushing?
PAO synthetic gear oils are generally miscible with each other, so a complete system flush is not strictly required. However, mixing different additive packages can dilute the performance of both products. For best results, drain the old oil as completely as possible (including gearbox sump, piping, filters, and coolers) before refilling with the new product.
