SEPAC, Inc. has introduced the SEB-Max Series, a standardized line of spring-applied friction brakes built for aerospace and defense applications. The Elmira, New York-based manufacturer designed the series to deliver high-performance braking with shorter lead times than custom solutions. As a result, design engineers and procurement teams gain faster access to mission-ready components.
Highlights
- The SEB-Max line offers compact sizes from 1″ to 4″ diameters with lengths as short as 0.788″, targeting space-constrained defense and aerospace platforms.
- Power-off, spring-engaged operation provides fail-safe braking that activates automatically when power is removed.
- Operating temperatures span -67°F to 158°F, with corrosion-resistant coatings and non-organic materials for extreme environments.
- SEPAC holds AS9100D and ISO 9001 certifications, reinforcing its manufacturing quality and process control standards.
Key Technical Specifications
The SEB-Max Series targets engineers who need reliable braking without extended custom-design timelines. SEPAC built the line on four decades of motion control expertise. The units combine durability and aerospace-grade performance in a compact, ready-to-order package.
Core specifications include:
- Diameter range: 1″ to 4″
- Unit lengths: 0.788″ to 2.397″
- Power requirements: 28VDC to release, 8VDC holding
- Operating temperature: -67°F to 158°F
- Environmental protection: Corrosion-resistant coatings for salt, fog, and moisture resistance
- Material construction: Non-organic materials to prevent fungus or microbial growth
Additionally, the low current and wattage design minimizes power consumption and heat generation. This makes the brakes well suited for weight- and power-sensitive aerospace platforms.
Fail-Safe Design for Critical Applications
The SEB-Max units function as power-off, spring-engaged brakes. In other words, they automatically engage when electrical power is removed. This fail-safe characteristic is essential for static holding and emergency braking functions in mission-critical systems.
SEPAC’s electromagnetic clutches and brakes already serve a broad range of defense and aerospace platforms. For instance, the company’s products are deployed in helicopters, satellites, missiles, commercial and military aircraft, and armored vehicles. The SEB-Max line extends that capability with standardized options.
Streamlined Procurement and Availability
According to John Meier, President at SEPAC, Inc., the series represents a shift in the company’s product strategy. Meier noted that the standardized options reduce design complexity and procurement time for aerospace and defense manufacturers.
The SEB-Max Series is now available for quote and order through SEPAC’s sales network and online request system. Detailed product specifications, CAD models, and support materials are available on the SEPAC website.
