Industrial SU Style
The SU Type coupling includes a single flex plane with two hubs plus a single disc pack. It is actually ideal for angular and axial misalignment only. Two SU couplings are sometimes mixed with a shaft
to generate a floating shaft coupling. The shaft may be hollow for lengthy light fat floating shaft couplings.
Industrial SX Form
This is the conventional coupling form that incorporates two hubs, a stock length spacer developed to meet field conventional lengths, and two unitized disc packs. The coupling has two flex planes, a single at every single disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and 8 bolt patterns and bore sizes up to 13 inches (330mm) about the greatest size. Customized spacer lengths is often produced to meet special 
shaft separations demanded for certain applications. The SX coupling can be fitted with overload bushings to protect the disc packs in more than torque situations and might act as an anti-flail gadget. SX couplings are assembled with the time of installation within the tools where the coupling is going to be in service.
Industrial DI Variety
The DI Type coupling has a “Drop-In” spacer assembly that is certainly assembled with the factory. The coupling includes two hubs along with a spacer assembly comprising of the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings at the factory utilizing the torque values proposed by Lovejoy for that disc pack bolts. Together with the hubs mounted within the shafts, the complete disc pack assembly is often “Dropped In” place between the two hubs. The hubs are piloted to guarantee appropriate centering of the spacer assembly. This piloting serves as an anti-flail characteristic and aids within the coupling’s capability to meet the balance requirements mandated by API. This style coupling is designed to meet the balance and anti-flail demands specified in API-610.
Oversized, or Jumbo, hubs are available for use with the DI Style coupling to permit for larger bore sizes on most DI coupling sizes. This enables for that use of smaller sized DI couplings in applications where a smaller sized dimension coupling can nonetheless accommodate the application torque.
Industrial SXC Kind
The SXC Type is the near coupled variation from the SX Form coupling. The SXC is similar to the SX coupling in the disc packs are connected once the coupling is put in. During the close coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that together with the hubs inside the spacer, the utmost bore permitted from the hub will probably be decreased. The SXC couplings might be made use of with one particular or each hubs turned outward to allow the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Varieties have split spacers as well as the disc packs may be serviced or removed with out moving the hubs to the shafts and without moving the equipment. The SXCS Sort has the bolts that connect the hubs for the split spacer set up in the ends with the couplings. The SXCST have the bolts put in from within the spacer pointing outward towards the hubs.
