SEPAC Announces Launch of SEB-Max Spring Applied Friction Brake Line Designed for Aerospace & Defense Applications

Elmira, New York–(Newsfile Corp. – February 13, 2026) – SEPAC, Inc., a leading U.S. manufacturer of precision electromagnetic clutches and brakes, today announced the launch of the SEB-Max™ Series, a new line of spring applied friction brakes engineered specifically for the aerospace and defense industries. The SEB-Max™ line brings to market a line of standardized products designed for reliability in the toughest environments and with the most stringent requirements — enabling simplified selection and faster delivery for mission-critical applications.

Built on the foundation of SEPAC’s four decades of motion control expertise, the SEB-Max™ line combines reliability, durability, and aerospace-grade performance into compact, ready-to-order units. These brakes are designed to serve customers who require high-performance brake solutions with shorter lead times than custom designs.

“The SEB-Max™ series represents a significant evolution in SEPAC’s product portfolio,” said John Meier, President at SEPAC, Inc. “We’ve taken the robust performance and field credibility of our long-standing spring engaged brakes and developed a standardized set of options that reduce design complexity and procurement time for aerospace and defense manufacturers.”

High-Performance Standards for Critical Applications

The SEB-Max™ Series is engineered for reliability in demanding environments, and features:

• Compact size ranging from 1″ to 4″ diameters with lengths as short as 0.788″ to 2.397″.

• Low current/wattage design to minimize power consumption and heat generation. 28VDC to power to release, 8VDC holding.

• Operating temperature range from -67°F to 158°F, suitable for extreme aerospace and defense environments.

• Corrosion resistant coatings for protection against salt, fog, and moisture.

• Non-organic materials to eliminate the risk of fungus or microbial growth.

Designed as power-OFF spring engaged brakes, the SEB-Max™ units automatically engage when power is removed — offering fail-safe operation critical for static holding or emergency brake functions.

Supporting Aerospace & Defense System Requirements

SEPAC’s products have long supported a wide range of aerospace and defense applications, from flight-control actuators to missile control surfaces and beyond. SEPAC’s electromagnetic clutches and brakes — engineered to meet rigorous industry standards — are deployed in helicopters, satellites, missiles, commercial and military aircraft, armored vehicles, and other mission critical platforms.

With AS9100D and ISO 9001 certifications underpinning its manufacturing quality and process control, SEPAC continues to serve customers who demand high reliability and precision. The addition of SEB-Max™ standard products enhances SEPAC’s ability to support design engineers, project managers, and procurement teams with faster access to high-quality brakes. SEPAC, Inc.
