• Custom Flexible Disc Couplings

Headquartered in Wisconsin, PSC Couplings’ mission is to bring a significant increase in value and service to the flexible coupling market with a product 100% made in the USA.


PSC designs and produces high quality drop-out spacer disc couplings. 

  • High quality is assured with all manufacturing and assembly completed in the United States.

  • Installation and service are simplified with disc pack cartridge assemblies that are fully unitized, collapsible, and self-piloting all with the use of standard fasteners. 

  • Product complexity and costs are reduced compared to the competition with 12 coupling sizes covering a wide range of torque ratings (from 2,500 in-lbs to 3,500,000 in-lbs continuous torque)

  • All couplings are fully customizable.

Industry Leading Product Features:
  • Manufactured with tight tolerances that provide an AGMA Class 9 balance as standard (AGMA Class 10 and Class 11 optional).

  • Made with high strength alloy steel hubs to provide improved strength and allow for an optimized maximum bore.

  • Unitized disc pack simplifies assembly and maintenance and provides improved performance.

  • Assembled with high strength socket head cap screws that are commercially available. This allows customers to easily replace fasteners, unlike competitor’s couplings that use expensive proprietary body ground shoulder bolts.
