Industrial SU Variety
The SU Variety coupling features a single flex plane with two hubs and a single disc pack. It’s appropriate for angular and axial misalignment only. Two SU couplings are sometimes combined with a shaft
to produce a floating shaft coupling. The shaft might be hollow for extended light excess weight floating shaft couplings.
Industrial SX Style
This really is the standard coupling form that contains two hubs, a stock length spacer created to meet field normal lengths, and two unitized disc packs. The coupling has two flex planes, 1 at every single disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and 8 bolt designs and bore sizes as much as 13 inches (330mm) to the largest dimension. Customized spacer lengths might be manufactured to meet particular shaft separations demanded for certain applications. The SX coupling might be fitted with overload bushings to guard the disc packs in in excess of torque situations and will act as an anti-flail gadget. SX couplings are assembled with the time of set up over the equipment in which the coupling might be in support.
Industrial DI Style
The DI Type coupling features a “Drop-In” spacer assembly which is assembled with the factory. The 
coupling consists of two hubs plus a spacer assembly comprising with the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings in the factory using the torque values encouraged by Lovejoy to the disc pack bolts. With all the hubs mounted about the shafts, the complete disc pack assembly could be “Dropped In” spot amongst the 2 hubs. The hubs are piloted to make certain appropriate centering with the spacer assembly. This piloting serves as an anti-flail characteristic and aids while in the coupling’s capacity to meet the stability requirements mandated by API. This style coupling is designed to meet the stability and anti-flail demands specified in API-610.
Oversized, or Jumbo, hubs can be found for use with all the DI Variety coupling to permit for larger bore sizes on most DI coupling sizes. This permits to the use of smaller DI couplings in applications wherever a smaller size coupling can even now accommodate the application torque.
Industrial SXC Kind
The SXC Style will be the shut coupled variation of your SX Form coupling. The SXC is much like the SX coupling in the disc packs are connected once the coupling is installed. During the close coupled units, the hubs are turned inward and are mounted inside the spacer. Note that using the hubs within the spacer, the utmost bore allowed within the hub will likely be decreased. The SXC couplings is often employed with one or both hubs turned outward to permit the coupling to accommodate different shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Sorts have split spacers as well as the disc packs can be serviced or eliminated without the need of moving the hubs over the shafts and without the need of moving the tools. The SXCS Variety has the bolts that connect the hubs on the split spacer installed through the ends on the couplings. The SXCST possess the bolts put in from within the spacer pointing outward in direction of the hubs.
