Industrial SU Form
The SU Style coupling features a single flex plane with two hubs as well as a single disc pack. It truly is suitable for angular and axial misalignment only. Two SU couplings tend to be combined that has a shaft
for making a floating shaft coupling. The shaft is usually hollow for extended light weight floating shaft couplings.
Industrial SX Sort
This really is the standard coupling form that involves two hubs, a stock length spacer designed to meet sector typical lengths, and two unitized disc packs. The coupling has two flex planes, one at every disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in six and 8 bolt models and bore sizes up to 13 inches (330mm) around the greatest size. Customized spacer lengths might be produced to meet special shaft separations essential for unique applications. The SX coupling is often fitted with overload bushings to protect the disc packs in over torque situations and will act as an anti-flail device. SX couplings are assembled at the time of installation within the tools wherever the coupling will likely be in service.
Industrial DI Kind
The DI Form coupling includes a “Drop-In” spacer assembly that’s assembled in the factory. The coupling includes two hubs along with 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 in the factory applying the torque values recommended by Lovejoy for the disc pack bolts. With the hubs mounted around the shafts, the whole disc pack assembly is often “Dropped In” area amongst the 2 hubs. The hubs are piloted to be sure proper centering of the spacer assembly. This piloting serves as an anti-flail feature and aids in the coupling’s capacity to meet the stability requirements mandated by API. This fashion coupling is built to meet the balance and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs can be found for use with the DI Kind coupling to allow for more substantial bore sizes on most DI coupling sizes. This allows to the utilization of smaller DI couplings in applications exactly where a smaller sized size coupling can nevertheless accommodate the application torque.
Industrial SXC Type
The 
SXC Variety is definitely the near coupled variation of your SX Type coupling. The SXC is similar to the SX coupling in that the disc packs are attached once the coupling is installed. Inside the near coupled units, the hubs are turned inward and are mounted within the spacer. Note that together with the hubs inside the spacer, the maximum bore allowed while in the hub will be decreased. The SXC couplings is usually utilised with a single or both hubs turned outward to allow the coupling to accommodate unique shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Sorts have split spacers and also the disc packs may be serviced or removed without moving the hubs around the shafts and without the need of moving the equipment. The SXCS Kind has the bolts that connect the hubs for the split spacer installed from the ends in the couplings. The SXCST have the bolts installed from inside the spacer pointing outward in the direction of the hubs.
