Industrial SU Kind
The SU Type coupling features a single flex plane with two hubs in addition to a single disc pack. It’s ideal for angular and axial misalignment only. Two SU couplings are often mixed that has a shaft
to create a floating shaft coupling. The shaft might be hollow for extended light bodyweight floating shaft couplings.
Industrial SX Variety
This can be the regular coupling sort that incorporates two hubs, a stock length spacer developed to meet industry normal lengths, and two unitized disc packs. The coupling has two flex planes, a single at each and every disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in 6 and 8 bolt types and bore sizes up to 13 inches (330mm) within the greatest size. Custom spacer lengths is often produced to meet particular shaft separations essential for certain applications. The SX coupling can be fitted with overload bushings to guard the disc packs in over torque conditions and might act as an anti-flail device. SX couplings are assembled on the time of installation within the products exactly where the coupling is going to be in services.
Industrial DI Form
The DI Form coupling has a “Drop-In” spacer assembly that is certainly assembled at the factory. The coupling includes two hubs in addition to 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 on the factory using the torque values proposed by Lovejoy for the disc pack bolts. With all the hubs mounted within the shafts, the complete disc pack assembly can be “Dropped In” spot between the two hubs. The hubs are piloted to make sure proper centering with the spacer assembly. This piloting serves as an anti-flail attribute and aids during the coupling’s means to meet the stability requirements mandated by API. This design coupling is made to meet the balance and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs are available for use together with the DI Style coupling to permit for more substantial bore sizes on most DI coupling sizes. This allows to the use of smaller DI couplings in applications the place a smaller sized size coupling can nevertheless accommodate the application torque.
Industrial SXC Form
The SXC Type is the shut coupled variation of your SX Sort coupling. The SXC is much like the SX coupling in the disc packs are attached when the coupling is put in. Within the shut coupled units, the hubs are turned 
inward and are mounted within the spacer. Note that with the hubs within the spacer, the utmost bore permitted in the hub might be decreased. The SXC couplings may be made use of with one or both hubs turned outward to allow the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Forms
The SXCS and SXCST Types have split spacers and also the disc packs may be serviced or removed devoid of moving the hubs to the shafts and with out moving the gear. The SXCS Style has the bolts that connect the hubs to the split spacer set up from your ends in the couplings. The SXCST have the bolts put in from within the spacer pointing outward in direction of the hubs.
