Datasheet EKS

Product catalog summary

Overview: The document provides technical specifications for the EKS series elastomer couplings, which are designed to be pluggable, backlash-free, and vibration-damping. These couplings feature an expanding cone hub with radial clamping, requiring minimal space due to their short overall length and integrated attachment.

Technical Specifications:

Temperature Range: -30°C to +90°C
Materials:
- Clamping Hubs: High-strength aluminum
- Expansion Cone Hub: Heat-treated steel
- Elastomer Spider: Polyurethane 98 Sh-A
- Screws: ISO 4762 12.9 - coated
Dimensions: Length dimensions conform to DIN ISO 2768 cH

Application Example: The EKS coupling can be integrated on the output side of a gear unit. The corresponding shaft hole for the expansion cone spigot should have a manufacturing tolerance of H7.
