Industrial SU Type
The SU Type coupling has a single flex plane with two hubs and a single disc pack. It’s suitable for angular and axial misalignment only. Two SU couplings tend to 
be combined by using a shaft
to produce a floating shaft coupling. The shaft may be hollow for long light excess weight floating shaft couplings.
Industrial SX Kind
This is the regular coupling variety that includes two hubs, a stock length spacer developed to meet field conventional lengths, and two unitized disc packs. The coupling has two flex planes, 1 at every single disc pack, making it possible for this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and 8 bolt models and bore sizes up to 13 inches (330mm) within the largest size. Custom spacer lengths could be manufactured to meet exclusive shaft separations necessary for precise applications. The SX coupling is often fitted with overload bushings to safeguard the disc packs in in excess of torque circumstances and may act as an anti-flail gadget. SX couplings are assembled on the time of set up within the products in which the coupling are going to be in services.
Industrial DI Variety
The DI Style coupling has a “Drop-In” spacer assembly that may be assembled on 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 for the spacer and guard rings at the factory using the torque values suggested by Lovejoy for that disc pack bolts. Using the hubs mounted on the shafts, the whole disc pack assembly could be “Dropped In” location in between the 2 hubs. The hubs are piloted to make sure good centering on the spacer assembly. This piloting serves as an anti-flail characteristic and aids inside the coupling’s skill to meet the stability requirements mandated by API. This design coupling is built to meet the stability and anti-flail demands specified in API-610.
Oversized, or Jumbo, hubs are available for use together with the DI Variety coupling to permit for larger bore sizes on most DI coupling sizes. This enables for the use of smaller DI couplings in applications exactly where a smaller sized dimension coupling can nonetheless accommodate the application torque.
Industrial SXC Sort
The SXC Form would be the close coupled variation on the SX Style coupling. The SXC is similar to the SX coupling in that the disc packs are attached when the coupling is set up. In the close coupled units, the hubs are turned inward and are mounted inside the spacer. Note that using the hubs within the spacer, the maximum bore permitted during the hub will probably be decreased. The SXC couplings may be made use of with a single or the two hubs turned outward to permit the coupling to accommodate unique shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Sorts have split spacers as well as the disc packs might be serviced or removed without having moving the hubs within the shafts and devoid of moving the tools. The SXCS Form has the bolts that connect the hubs on the split spacer installed in the ends from the couplings. The SXCST possess the bolts set up from within the spacer pointing outward towards the hubs.
