Disc Coupling Overview

Industrial SU Sort
The SU Kind coupling has a single flex plane with two hubs as well as a single disc pack. It’s suitable for angular and axial misalignment only. Two SU couplings tend to be mixed having a shaft
to create a floating shaft coupling. The shaft is usually hollow for extended light weight floating shaft couplings.
Industrial SX Variety
This is often the regular coupling form that includes two hubs, a stock length spacer built to meet field normal lengths, and two unitized disc packs. The coupling has two flex planes, one at each disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in 6 and eight bolt styles and bore sizes as much as 13 inches (330mm) to the greatest dimension. Custom spacer lengths may be produced to meet exclusive shaft separations demanded for specific applications. The SX coupling can be fitted with overload bushings to guard the disc packs in in excess of torque circumstances and might act as an anti-flail device. SX couplings are assembled with the time of set up around the gear in which the coupling will likely be in services.
Industrial DI Kind
The DI Type coupling has a “Drop-In” spacer assembly that may be assembled at the factory. The coupling consists of two hubs as well as 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 that disc pack bolts. With all the hubs mounted around the shafts, the whole disc pack assembly is often “Dropped In” location among the 2 hubs. The hubs are piloted to guarantee correct centering on the spacer assembly. This piloting serves as an anti-flail function and aids in the coupling’s potential to meet the stability specifications mandated by API. This fashion coupling is designed to meet the balance and anti-flail specifications specified in API-610.
Oversized, or Jumbo, hubs are available for use together with the DI Kind coupling to permit for bigger bore sizes on most DI coupling sizes. This permits to the use of smaller sized DI couplings in applications where a smaller sized dimension coupling can still accommodate the application torque.
Industrial SXC Sort
The SXC Variety is the shut coupled variation of your SX Sort coupling. The SXC is much like the SX coupling in the disc packs are connected once the coupling is put in. In the close coupled units, the hubs are turned inward and are mounted within the spacer. Note that together with the hubs within the spacer, the utmost bore permitted within the hub will likely be decreased. The SXC couplings might be used with 1 or each hubs turned outward to permit the coupling to accommodate unique shaft separations.
Industrial SXCS and SXCST Forms
The SXCS and SXCST Forms have split spacers and the disc packs could be serviced or removed without the need of moving the hubs about the shafts and devoid of moving the equipment. The SXCS Variety has the bolts that connect the hubs on the split spacer put in through the ends on the couplings. The SXCST possess the bolts set up from inside the spacer pointing outward in direction of the hubs.
