Configuration and Spider Compatibility
Elastomer spider selection for KTR GS 14.
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 |
|---|---|---|---|---|
| 80 ShA-GS | 80 Shore A | Polyurethane | -50 C to +80 C | Exceptional vibration damping; ideal for electrical measuring systems. |
| 92 ShA-GS | 92 Shore A | Polyurethane | -40 C to +90 C | Standard automation, control systems, and main spindle drives. |
| 98 ShA-GS | 98 Shore A | Polyurethane | -30 C to +90 C | Standard high-dynamic positioning drives and machine spindles. |
| 64 ShD-H-GS | 64 Shore D | Hytrel | -50 C to +120 C | Designed for planetary gears and backlash-free gear drives. |
