About Sargent Aerospace Hydraulics

The Sargent Story
In 1920 Sumner Benedict Sargent sold a patent he had obtained to the oil industry in order to found the Sargent Engineering Company. The first factory was a 800 square foot shed in Sargent’s back yard in Huntington Park, CA. In the 1940s the Sargent Engineering Company’s business shifted to aerospace and defense to support the growing WWII effort. Sargent’s unwavering focus on solving difficult application problems via an innovative engineering approach led to The Sargent Engineering Company becoming a highly regarded, and respected partner in the aerospace and defense industry.

Since its humble beginnings in 1920 The Sargent Engineering Company has become Sargent Aerospace and Defense and has grown into one of the world’s leading suppliers of highly engineered, specialty hydraulic actuation products serving the aerospace, defense, and space markets.

About Sargent
Today, Sargent resides in a 150,000 square foot facility in Tucson, AZ, and as part of the RBC Bearings, Sargent Aerospace and Defense continues Sumner Benedict Sargent’s legacy of solving difficult problems via a mission of making the challenging a reality, delivering high quality products and services that meet customer requirements and exceed customer expectations. One of Sargent’s top priorities is to develop close working relationships with our customers, and become part of their engineering problem solving process.

Sargent Aerospace and Defense’s Tucson facility serves as RBC Bearings’ center of excellence for commercial and military hydraulic actuation design, qualification/testing, and hydraulic component manufacturing and assembly for aerospace OEMs and aftermarket. The Sargent Tucson facility is ISO 9001:2015 and AS9100D accredited as well as NADCAP certified for non-destructive testing (NDT).

Hydraulic Actuators, Sargent Aerospace and Defense

Hydraulic actuators play a critical role on various aircraft system. From landing gears to outer doors, hydraulic actuators are the tool used to move heavy objects or surfaces exposed to high loads. Sargent has been supporting the aerospace industry with hydraulic actuators that perform for the life of the aircraft, or spacecraft, and routinely support ultimate loads in excess of 50,000 lbs.

Snubber rings can be Sargent utility actuators in aerospace applications: on landing gear used on:

• Landing gear extend, retract, downlock, uplock
• External doors
• Thrust reversers
• Wing fold / Rotor fold

Actuator Benefits include:

• Auto or manual mechanical locking
• Lock and position sensing
• Rate of motion control
• End of stroke damping

Hydraulic Uplock / Downlock, Sargent Aerospace and Defense

Landing gears are critical systems in any aerospace platform. When the gear is stowed or deployed it is critical that the gear stays in that position, even if there is a failure in the hydraulic system. This is where uplock and downlock assemblies play a critical role. By leveraging manufacturing, structure knowledge, and hydraulic design selection, Sargent can support manufacturing of an entire assembly saving customers from having to source critical components from multiple suppliers.

Sargent uplocks / downlocks are commonly found in:

• Aircraft landing gear
• Spacecraft landing gear

Uplock / Downlock characteristics can include:

• Hydraulic component integration
• Status indication (depending upon design)
• Weight optimization
