Construction & Working Principle

Components:
Rigid Metallic Hub(s):
• Manufactured from high-strength steel or cast iron

Fastening Elements (Bolts / Keys / Clamps):
• Ensure secure shaft connection and torque transmission

Working Principle:
Torque is transmitted through a direct mechanical connection between two shafts using rigid hubs. Since there are no flexible elements, the coupling does not accommodate misalignment, requiring precise shaft alignment for optimal performance.
