Configuration and Spider Compatibility
Elastomer spider selection for KTR GS 75.
ROTEX GS coupling role
Backlash-free jaw coupling with elastomer spider under compression. Spider hardness governs damping, temperature limits and torsional stiffness.
Compatible elastomer spiders
| Spider | Hardness | Material | Temperature range | Application characteristics |
|---|---|---|---|---|
| 98 ShA-GS | 98 Shore A | Polyurethane | -30 C to +90 C | Standard high-dynamic positioning drives and machine spindles. |
| 64 ShD-GS | 64 Shore D | Polyurethane | -20 C to +110 C | High torsional rigidity; suited for heavy-load AC servo drives. |
| 72 ShD-GS | 72 Shore D | Polyurethane | -20 C to +110 C | High torque/torsional rigidity; for indexing tables. |
