The Hilliard Corporation was founded in 1905 with a single breakthrough clutch. Over the last 120 years, that innovation has grown into a legacy of engineering solutions that serve industries around the world.

Our journey has been defined by innovation, engineering expertise, and a relentless commitment to quality. From motion control to braking and filtration technologies, Hilliard has built a reputation for reliability and excellence that customers have trusted for generations.

This anniversary is more than a milestone. It is a celebration of our people, our customers, and our partners who made 120 years possible, and a reflection of the values that continue to guide our future.

Hilliard products are designed, manufactured, and sold according to our customers' applications. As a result, we have a large range of custom-engineered products that can be modified to meet new applications. With a sound understanding of engines and filtration devices, Hilliard engineers design complete systems, including electromechanical interfaces. Hilliard often works with customers to research and test products, acting as a lab for specific applications.

Hilliard delivers high-performance braking solutions engineered for the demands of elevator modernization. Our Spring Applied/Electric Released Brakes automatically engage during power loss and release electrically, providing reliable, fail-safe operation. With torque ratings from 7.5 to 4,500 lb-ft, a range of voltage options, and features like epoxy-potted coils and adjustable wear compensation, these brakes are built for durability, safety, and reduced maintenance.

MK Rail & Disc Brakes feature a direct-acting design with a single moving part, ensuring low maintenance and dependable performance. Our spring-applied, electrically released brakes offer precise holding and emergency stopping power. They are configurable for a variety of rail and disc sizes and include manual release bolts and microswitches for brake status monitoring.

Both systems integrate seamlessly into modernized elevator platforms and are designed to enhance safety, minimize downtime, and extend service life.
