How Gatke Compares to Alternative Materials
| Materials | Cost Difference | Advantages | Disadvantages |
| Babbitt | +75 to 100% | Old worn or misaligned equipment | Lead-based, need for a casting, & machining – environmental concerns |
| UHMW | – 50% | Lower Price | Can’t take more than 250 degrees F |
| Bronze | + 0 to 25% | Accepted technology – easy to machine – been around for a long period of time | Three times heavier than Gatke – permanent deformation – environmental concerns |
| Steel | – 25% | Good heat resistance | Very aggressive wear on shaft & galling |
| Other Phenolics | +/- 10% | More cost effective in smaller diameters – sizing in some instances | Size limitations – we can produce larger diameter |
