Product Design Details.

Disc Pack Cartridge

  • Disc packs cartridges assembled as single units at PSC’s facility.
  • All components of the disc pack have precise locations.
  • Threaded bushings transfer torque and provide clamping force.

Fasteners

  • Fasteners required only to provide a compressive force on the disc packs, so standard fasteners can be used.
  • Socket head cap screws are used to allow larger bores.

Hubs

  • Scallops provide stress relief over keyway and allow for larger bores and higher torque density.

Material

  • All alloy steel construction with stainless steel discs.

Product Advantages.

Series 57 Drop Out Spacer Disc Coupling

Exploded View of Disc Pack Cartridge

Quick and Easy Installation and Service

  • Quick and Easy Installation and Service
  • Self-piloting, fully assembled, and collapsible disc pack cartridges are easily positioned in the flexible disc coupling with hub and center member pilot bores.
  • Standard cap screw fasteners readily available.

Balanced by Design

  • Precisely manufactured components allow for AGMA class 9 (class 10 or class 11 as options).
  • All components have precise locations within the assembly.
  • All components are interchangeable for all AGMA classes (as opposed to ISO balance grades).

High Torque Transmitted Through Bushings and Discs

  • High friction coating provides locking of disc pack.
  • Disc pack exhibits no slip through peak torque.
  • Standard cap screw fasteners in tension only (not required to resist bending moment or shear force).

Large Bore Capability with Socket Head Cap Screws

  • Socket Head Cap Screws
  • Socket head fasteners allow larger bores to be used.
