The
Shrink Disc is a
keyless locking device that achieves tight shaft–hub connections through high clamping forces generated by preloaded bolts. As the
forged blank foundation of this component, it must provide
high strength and dimensional stability to withstand significant pre-tightening forces. The uniform material quality and Forging integrity ensure reliable locking performance and high assembly accuracy in the final product.

Industry Applications
Our shrink disc
Forged Blanks are forged through ring rolling forging, ensuring high strength and dimensional stability for critical shaft–hub connection systems. While currently serving wind turbine drive train assemblies, they are also widely applicable in other industries:
- Wind Power – Shaft-hub couplings connecting generator, gearbox, and main shaft.
- Construction Machinery – Wheel hub and reducer connections for heavy mobile equipment.
- Mining Equipment – Torque transmission couplings in crushers and mills.
- Industrial Power Transmission – Pulley and sprocket connections for high-load drives.
- Automation & Robotics – High-precision locking assemblies in servo systems.
