Industrial SU Style
The SU Kind coupling has a single flex plane with two hubs and a single disc pack. It is actually appropriate for angular and axial misalignment only. Two SU couplings are sometimes mixed by using a shaft
to make a floating shaft coupling. The shaft is usually hollow for lengthy light weight floating shaft couplings.
Industrial SX Style
This really is the normal coupling type that includes two hubs, a stock length spacer built to meet field normal lengths, and two unitized disc packs. The coupling has two flex planes, a single at every single disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in 6 and eight bolt designs and bore sizes up to 13 inches (330mm) on the largest dimension. Custom spacer lengths may be produced to meet particular shaft separations essential for precise applications. The SX coupling might be fitted with overload bushings to safeguard the disc packs in over torque circumstances and might act as an anti-flail gadget. SX couplings are assembled with the time of installation over the gear the place the coupling will likely be in services.
Industrial DI Style
The DI Type coupling includes a “Drop-In” spacer assembly which is assembled in the factory. The coupling consists of two hubs as well as a spacer assembly comprising in 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 encouraged by Lovejoy for your disc pack bolts. Together with the hubs mounted around the shafts, the whole disc pack assembly could be “Dropped In” place involving the two hubs. The hubs are piloted to guarantee suitable centering in the spacer assembly. This piloting serves as an anti-flail function and aids while in the coupling’s capacity to meet the balance requirements mandated by API. This 
type coupling is created to meet the balance and anti-flail specifications specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Style coupling to allow for bigger bore sizes on most DI coupling sizes. This allows for your use of smaller DI couplings in applications the place a smaller size coupling can nonetheless accommodate the application torque.
Industrial SXC Variety
The SXC Variety is the near coupled variation of your SX Type coupling. The SXC is just like the SX coupling in that the disc packs are attached once the coupling is put in. During the close coupled units, the hubs are turned inward and are mounted inside the spacer. Note that together with the hubs inside the spacer, the maximum bore permitted within the hub will be decreased. The SXC couplings is usually utilised with a single or the two hubs turned outward to permit the coupling to accommodate unique shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Kinds have split spacers as well as the disc packs can be serviced or removed with out moving the hubs about the shafts and devoid of moving the tools. The SXCS Variety has the bolts that connect the hubs to the split spacer set up from the ends of your couplings. The SXCST possess the bolts set up from within the spacer pointing outward in the direction of the hubs.
