York Precision Machining & Hydraulics LLC has the right solution to enhance the safety of your defense or security equipment. We've designed our Bear-Loc® hydraulic locking system specifically for use in these and other high-demand industries.

Bear-Loc® is a hydraulic rod locking device that has earned the trust of the world’s top defense organizations and companies in a wide range of industries due to its advanced design, ease of use and safety. The fail-safe reliability ensures the rod will meet the challenge of defense and security applications. The design does not depend on moving parts which enhances its reliability and minimizes wear. The Bear-Loc® is a true positive mechanical lock, which means that it locks instantly when pressure is removed, either intentionally or accidentally.

Bear-Loc®is also extremely versatile. Its unique flexibility allows you to achieve an unlimited number of locking positions and a wide variety of configurations. You can use it for virtually any hydraulic application.

We have incorporated the Bear-Loc into elevation actuators, stabilizer/outrigger applications, and in securing rockets/munitions. Here are two examples of applications:

Defense, Security & Aerospace Markets

Missile Launchers

Missile launchers used by the military continue to advance in terms of technological innovations, and they generally include state-of-the-art hydraulic systems that require the latest safety features. A Bear-Loc® hydraulic rod lock system for missile launchers assures mission success by providing the accuracy and stability that these powerful machines require. Its failsafe reliability protects the lives of U.S. military while its ease of use helps keep personnel out of harm’s way.

Inspection Vehicles

In U.S. border security and major events like the Super Bowl, inspection vehicles assure that vehicles seeking to gain entry do not contain dangerous or unlawful cargo. A Bear-Loc®serves as the locking and holding device for a hydraulic actuator that lifts the machine's inspecting arm, making it possible to scan suspicious objects, large containers, and vehicles of any size. The Bear-Loc®holds the inspecting arm in position for however long is necessary. If power removed or the failure of a hydraulic part or component occurs, Bear-Loc® locks instantly, keeping the arm in position and, thereby preventing a dangerous situation.
