Brake Drum Geared Coupling Manufacturer in Ahmedabad, India

Brake Drum Geared Coupling from Super Mech Industries is made in Ahmedabad, India in 8 catalogue sizes, SBDGC 4" to SBDGC 12", rated from 980 Nm to 31,500 Nm, with bores finished to order up to 110 mm.

Brake Drum Geared Couplings combine the torque-handling capacity of a geared coupling with an integrated brake drum for systems requiring both power transmission and mechanical braking. These couplings consist of two hubs with external gear teeth, connected by a sleeve with internal teeth. The brake drum is mounted as part of the coupling, allowing it to interface with braking systems. This makes them ideal for cranes, hoists, and material handling equipment where frequent start-stop operations and braking are required.
