Industrial SU Variety
The SU Sort coupling includes a single flex plane with two hubs and a single 
disc pack. It is appropriate for angular and axial misalignment only. Two SU couplings tend to be mixed with a shaft
to generate a floating shaft coupling. The shaft may be hollow for extended light excess weight floating shaft couplings.
Industrial SX Sort
This is certainly the conventional coupling form that consists of two hubs, a stock length spacer developed to meet business regular lengths, and two unitized disc packs. The coupling has two flex planes, 1 at each disc pack, making it possible for this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and 8 bolt models and bore sizes up to 13 inches (330mm) around the largest size. Customized spacer lengths can be produced to meet particular shaft separations necessary for specific applications. The SX coupling might be fitted with overload bushings to guard the disc packs in over torque situations and might act as an anti-flail device. SX couplings are assembled in the time of installation to the gear the place the coupling are going to be in service.
Industrial DI Style
The DI Kind coupling includes a “Drop-In” spacer assembly that is assembled on the factory. The coupling consists of two hubs along with 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 in the factory applying the torque values suggested by Lovejoy for that disc pack bolts. Together with the hubs mounted to the shafts, the entire disc pack assembly can be “Dropped In” location involving the 2 hubs. The hubs are piloted to guarantee correct centering of the spacer assembly. This piloting serves as an anti-flail characteristic and aids during the coupling’s capability to meet the stability standards mandated by API. This type coupling is intended to meet the balance and anti-flail demands specified in API-610.
Oversized, or Jumbo, hubs can be found for use with all the DI Variety coupling to allow for larger bore sizes on most DI coupling sizes. This allows for that use of smaller DI couplings in applications in which a smaller sized dimension coupling can nonetheless accommodate the application torque.
Industrial SXC Style
The SXC Kind is the shut coupled variation in the SX Sort coupling. The SXC is just like the SX coupling in that the disc packs are attached once the coupling is put in. Inside the near coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with all the hubs inside the spacer, the maximum bore permitted within the hub is going to be decreased. The SXC couplings may be employed with one particular or each hubs turned outward to permit the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Forms
The SXCS and SXCST Forms have split spacers and also the disc packs might be serviced or removed without the need of moving the hubs over the shafts and without moving the gear. The SXCS Form has the bolts that connect the hubs to the split spacer put in from the ends in the couplings. The SXCST have the bolts put in from inside the spacer pointing outward in the direction of the hubs.
