Grid Couplings

A grid coupling is a heavy-duty connector that uses a flexible, S-shaped strip of spring steel to link two shafts together and transmit power.
Here is the simple breakdown of what it does:
• Uses a Metal Spring: Instead of a solid piece of metal or rubber, a serpentine (snake-shaped) spring fits into slots on both sides of the coupling.
• Dampens Shocks: The spring bends and flexes to absorb impact energy and reduce vibrations by as much as 30%, protecting the machines attached to it.
• Handles Big Power: It combines the strength of a metal coupling with the flexibility of an elastic one, making it ideal for tough jobs in things like mining or steel mills.
• Needs Grease: The metal spring moves against the metal hubs, so the inside of the coupling must be packed with grease and sealed to work smoothly and prevent wear.
In short, a grid coupling is a resilient, strong connector that uses a spring to cushion shock loads while reliably transferring high power between shafts.
