Lovejoy 69790494932 DI-6 Type 90-6 Jumbo Hub Bolt Kit

The DI Type coupling has a “Drop-In” spacer assembly that is assembled at the factory. The coupling consists of two hubs and a spacer assembly comprising of the spacer, two unitized disc packs, and two guard rings. 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. This piloting serves as an anti-flail feature and aids in the coupling’s ability to meet the balance standards mandated by API. This style coupling is designed to meet the balance and anti-flail requirements specified in API-610.

Note: Bolt kits are generally INCLUDED when ordering a DI type hub. Unless ordered as a replacement part, bolt kits are generally not ordered as a stand alone item.

• Designed to meet the API 610 Standard
