Quick Answer
For most Indian heavy-industry buyers — steel plants, cement plants, conveyors, EOT cranes — SMI offers the shortest dispatch time, the only publicly stated indicative pricing, and current ISO 9001:2015 quality from an independent Ahmedabad manufacturer. Elecon Engineering makes fluid and scoop-controlled variable-speed couplings as well as ELIGN gear couplings rated to 1,100,000 N·m; SMI's FG range reaches 1,666,744 Nm. Rathi/Ringfeder or Renold when API or ATEX certification is mandatory. Lovejoy or Renold when an international project demands a globally recognised brand backed by Timken or Renold plc global stock.
