Industrial SU Style
The SU Kind coupling has a single flex plane with two hubs plus a single disc pack. It is actually suitable for angular and axial misalignment only. Two SU couplings are frequently combined which has a shaft
to generate a floating shaft coupling. The shaft could be hollow for extended light bodyweight floating shaft couplings.
Industrial SX Variety
That is the regular coupling kind that consists of two hubs, a stock length spacer built to meet business standard lengths, and two unitized disc packs. The coupling has two flex planes, 1 at each and every 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) within the biggest dimension. Custom spacer lengths could be produced to meet distinctive shaft separations necessary for distinct applications. The SX coupling could be fitted with overload bushings to protect the disc packs in above torque conditions and can act as an anti-flail gadget. SX couplings are assembled at the time of set up around the gear wherever the coupling will likely be in services.
Industrial DI Sort
The DI Form coupling includes a “Drop-In” spacer assembly that’s assembled on the factory. The coupling consists of two hubs in addition to a spacer assembly comprising of your spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings in the factory working with the torque values recommended by Lovejoy for that disc pack bolts. With the hubs mounted about the shafts, the whole disc pack assembly is usually “Dropped In” place amongst the two hubs. The hubs are piloted to ensure correct centering of the spacer assembly. This piloting serves as an anti-flail characteristic and aids during the coupling’s means to meet the stability specifications mandated by API. This fashion coupling is made to meet the stability and anti-flail specifications specified in API-610.
Oversized, or Jumbo, hubs are available for use using the DI Form coupling to permit for more substantial bore sizes on most DI coupling sizes. This permits for the utilization of smaller DI couplings in applications where a smaller sized dimension coupling can still accommodate the application torque.
Industrial SXC Form
The SXC Form is the shut coupled variation on the SX Style coupling. The SXC is much like the SX coupling in that the disc packs are connected when the coupling is set up. During the close coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that with all the hubs inside the spacer, the utmost bore permitted from the hub will be decreased. The SXC 
couplings is often utilized with one particular or both hubs turned outward to allow the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Forms have split spacers and the disc packs can be serviced or removed without having moving the hubs to the shafts and devoid of moving the gear. The SXCS Kind has the bolts that connect the hubs to your split spacer installed in the ends on the couplings. The SXCST have the bolts installed from within the spacer pointing outward in direction of the hubs.
