Industrial SU Type
The SU Style coupling features a single flex plane with two hubs and also a single disc pack. It truly is suitable for angular and axial misalignment only. Two SU couplings are sometimes mixed using a shaft
for making a floating shaft coupling. The shaft is usually hollow for lengthy light weight floating shaft couplings.
Industrial SX Style
This is the common coupling variety that includes two hubs, a stock length spacer developed to meet sector standard lengths, and two unitized disc packs. The coupling has two flex planes, 1 at each disc pack, enabling 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 as much as 13 inches (330mm) around the largest size. Custom spacer lengths may be manufactured to meet particular shaft separations essential for unique applications. The SX coupling may be fitted with overload bushings to guard the disc packs in more than torque problems and can act as an anti-flail gadget. SX couplings are assembled in the time of set up on the gear the place the coupling might be in services.
Industrial DI Kind
The DI Type coupling has a “Drop-In” spacer assembly that is assembled at the factory. The coupling includes two hubs and a spacer assembly comprising of the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings with the factory applying the torque values suggested by Lovejoy for the disc pack bolts. With the hubs mounted over the shafts, the whole disc pack assembly can be “Dropped In” spot amongst the two hubs. The hubs are piloted to ensure appropriate centering from the spacer assembly. This piloting serves as 
an anti-flail feature and aids within the coupling’s potential to meet the balance standards mandated by API. This type coupling is built to meet the balance and anti-flail demands specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Form coupling to allow for more substantial bore sizes on most DI coupling sizes. This allows for your use of smaller DI couplings in applications where a smaller size coupling can even now accommodate the application torque.
Industrial SXC Sort
The SXC Variety could be the shut coupled variation of your SX Kind coupling. The SXC is similar to the SX coupling in the disc packs are connected once the coupling is set up. During the near coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that with all the hubs within the spacer, the maximum bore permitted while in the hub will likely be decreased. The SXC couplings could be employed with 1 or both hubs turned outward to allow the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Forms
The SXCS and SXCST Kinds have split spacers and the disc packs could be serviced or removed without having moving the hubs around the shafts and devoid of moving the gear. The SXCS Style has the bolts that connect the hubs on the split spacer set up in the ends with the couplings. The SXCST possess the bolts set up from within the spacer pointing outward in direction of the hubs.
