Lovejoy DI278-6 Hub RSB
The DI Type coupling is the standard 6 bolt coupling with two hubs and a spacer assembly that can be installed or removed without disturbing the equipment and hubs and without removing the disc packs from the spacer assembly. The DI Type coupling has a “Drop-In” spacer assembly that is assembled at the factory. The disc packs are bolted to the spacer and guard rings at the factory using the torque values recommended by Lovejoy for the disc pack bolts. With the hubs mounted on the shafts, the entire disc pack assembly can be “dropped in” place between the two hubs. The hubs are piloted to ensure proper centering of the spacer assembly.
