Disc Coupling Overview

Industrial SU Type
The SU Kind coupling includes a single flex plane with two hubs and also a single disc pack. It is ideal for angular and axial misalignment only. Two SU couplings are often mixed having a shaft
for making a floating shaft coupling. The shaft could be hollow for lengthy light weight floating shaft couplings.
Industrial SX Style
This really is the standard coupling style that includes two hubs, a stock length spacer created to meet industry standard lengths, and two unitized disc packs. The coupling has two flex planes, one particular at every single disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and 8 bolt types and bore sizes up to 13 inches (330mm) to the largest size. Custom spacer lengths is usually produced to meet unique shaft separations needed for distinct applications. The SX coupling may be fitted with overload bushings to guard the disc packs in above torque problems and will act as an anti-flail device. SX couplings are assembled at the time of set up about the tools where the coupling might be in services.
Industrial DI Form
The DI Kind coupling features a “Drop-In” spacer assembly that is definitely assembled with the factory. The coupling includes two hubs as well as a spacer assembly comprising from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted towards the spacer and guard rings in the factory making use of the torque values recommended by Lovejoy for that disc pack bolts. With the hubs mounted about the shafts, the entire disc pack assembly is usually “Dropped In” place in between the two hubs. The hubs are piloted to ensure suitable centering from the spacer assembly. This piloting serves as an anti-flail attribute and aids inside the coupling’s capacity to meet the balance requirements mandated by API. This fashion coupling is developed to meet the balance and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs are available for use using the DI Type coupling to permit for bigger bore sizes on most DI coupling sizes. This permits for the use of smaller sized DI couplings in applications exactly where a smaller size coupling can nevertheless accommodate the application torque.
Industrial SXC Sort
The SXC Kind will be the near coupled variation in the SX Style coupling. The SXC is much like the SX coupling in the disc packs are connected once the coupling is installed. In the near coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that with the hubs inside the spacer, the maximum bore permitted in the hub will likely be decreased. The SXC couplings is often used with one or the two hubs turned outward to allow the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Sorts
The SXCS and SXCST Sorts have split spacers along with the disc packs could be serviced or removed without having moving the hubs over the shafts and with out moving the equipment. The SXCS Variety has the bolts that connect the hubs for the split spacer set up in the ends of your couplings. The SXCST have the bolts installed from within the spacer pointing outward in the direction of the hubs.
