Industrial SU Variety
The SU Form coupling includes a single flex plane with two hubs and a single disc pack. It 
truly is appropriate for angular and axial misalignment only. Two SU couplings are sometimes mixed which has a shaft
to produce a floating shaft coupling. The shaft is often hollow for long light excess weight floating shaft couplings.
Industrial SX Form
This is certainly the common coupling type that consists of two hubs, a stock length spacer developed to meet business normal lengths, and two unitized disc packs. The coupling has two flex planes, one at just about every disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in six and eight bolt styles and bore sizes up to 13 inches (330mm) within the largest dimension. Customized spacer lengths is often produced to meet special shaft separations needed for distinct applications. The SX coupling can be fitted with overload bushings to protect the disc packs in above torque ailments and can act as an anti-flail device. SX couplings are assembled at the time of set up within the products the place the coupling will probably be in support.
Industrial DI Kind
The DI Type coupling has a “Drop-In” spacer assembly that is certainly assembled at the factory. The coupling consists of two hubs along with a spacer assembly comprising on the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings with the factory making use of the torque values proposed by Lovejoy to the disc pack bolts. With all the hubs mounted over the shafts, the entire disc pack assembly could be “Dropped In” area amongst the 2 hubs. The hubs are piloted to make sure proper centering with the spacer assembly. This piloting serves as an anti-flail attribute and aids inside the coupling’s skill to meet the stability standards mandated by API. This type coupling is created 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 Type coupling to allow for bigger bore sizes on most DI coupling sizes. This permits for the use of smaller sized DI couplings in applications the place a smaller sized dimension coupling can even now accommodate the application torque.
Industrial SXC Kind
The SXC Type could be the near coupled variation on the SX Style coupling. The SXC is much like the SX coupling in the disc packs are connected once the coupling is set up. From the close coupled units, the hubs are turned inward and are mounted within the spacer. Note that together with the hubs inside the spacer, the utmost bore allowed while in the hub will be decreased. The SXC couplings could be made use of with 1 or each hubs turned outward to permit the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Sorts
The SXCS and SXCST Types have split spacers plus the disc packs is usually serviced or removed without the need of moving the hubs on the shafts and without having moving the products. The SXCS Style has the bolts that connect the hubs to your split spacer installed from your ends in the couplings. The SXCST have the bolts installed from within the spacer pointing outward in direction of the hubs.
