Company Overview

SEPAC, Inc. is a custom engineering manufacturer of electromagnetic clutches and brakes headquartered in Elmira, New York, USA. Founded in 1984 by Gary Packard and Curran Sekella (the company name combining syllables of both founders' surnames), SEPAC began as a two-person operation serving markets vacated by Purolator Facet/Bendix and has since grown into a fully integrated engineering and manufacturing company operating from a 28,000-square-foot facility.

The company's product portfolio covers electromagnetic brakes and electromagnetic clutches across two engagement styles—spring-applied and magnetically applied—and two torque transmission types: friction and tooth. Key product series include the SEB-Max (a high-performance spring-applied friction brake), SEB, TSEB, UTSEB, MSEB, SETB, MDB, PMB, METB (brakes) and SECC, SETC, SFDC, RFDC, SFTC, RFTC, STCC, WMTC (clutches). All products are designed and manufactured in the United States at the Elmira facility.

SEPAC serves six primary end markets: Robotics, Aviation/Aerospace, Defense, Medical, Energy, and Space. The company also supplies Microreactors and AI Data Center applications. Named OEM customers include Moog, General Electric, Honeywell, Boeing, Lockheed Martin, Zoll Medical, BAE Systems, Raytheon, Northrop Grumman, Hardinge, and Eaton.

Design capabilities rely on SolidWorks for mechanical modeling, COMSOL for magnetic FEA simulation, and SolidWorks for structural and thermal FEA. Manufacturing includes CNC turning centers with live tooling, five CNC milling centers (3- and 4-axis), single-point gear shapers, broach machines, and ID/OD grinders. Two fixed-base coordinate measuring machines (CMMs) and an optical comparator support in-house metrology, backed by over 600 calibrated gauges.

SEPAC holds AS9100D and ISO 9001 certifications. The company also operates sibling brands Mach III and Placid Industries. Its robotics-specific eBook, "Choosing the Right Brake for Robotic Applications," reflects its dedicated focus on motion-control components for robotic joints and actuators.
