Rod Locking Device - BEAR-LOC®

BEAR-LOC® is a reliable locking device which you can use where infinite position locking, zero backlash and high system stiffness are required.

BEAR-LOC® has a unique patented design based on the principle of elastic expansion of metal under pressure. It is simpler, more efficient and more reliable than any other available locking system on the market.

BEAR-LOC® has been designed in a wide range of sizes, with rod diameters from 1 inch to 27 inches, sleeve lengths from 1 inch to seven feet and lock capacities to 4 million pounds.

Infinite Position Locking

Fail-Safe Locking

Functional Design

Easy Maintenance

You can buy custom hydraulic locking devices for various applications in industries such as aerospace and defense. Safety is one of the most important benefits of using BEAR-LOC® products. By using the unlock port to remove the hydraulic pressure, you will allow the locking device to re-engage automatically. This ensures a totally automated operation even when accidental pressure loss occurs, virtually eliminating the potential for workplace accidents and injuries.

Hydraulic Cylinders & Actuators

We also offer custom-built hydraulic actuators and hydraulic cylinders for sale. Actuators facilitate hydraulic system operation by controlling the opening and closing of valves. They consist of a cylinder or motor that relies on hydraulic power to generate the desired mechanical process. Hydraulic cylinders are a type of actuator and contain a barrel, piston and piston rod that moves back and forth to deliver unidirectional force. Pressurized fluid supplies the power to the cylinder.

Our highly experienced staff has over 40 years of success in the design and manufacture of Hydraulic Actuators, Accumulators, and Cylinders for Industrial, Mobile, Aerospace and Defense applications.

Spec Sheet

Industrial/Piston Accumulators

Hydraulic accumulators act as a repository for hydraulic fluid. They allow the hydraulic system to adapt to fluctuations in demand when using a hydraulic pump with a reduced output capacity. They also enable the system to adapt more quickly to temporary demand changes. York PMH offers highly precise custom-built hydraulic accumulators for sale featuring:

Safety vents in gas and liquid ends warn of internal pressurization

Aluminum piston with anodized finish resists pitting

T-Seal with dual back-up rings assure separation with minimum drag

Dual outboard wear strips prevent piston rub and provide larger balanced bearing areas.

Oil or water service availability

-20°F to 275°F operating temperature range

Optional safety fuse

Custom designed to your specifications

Other material types available, contact for more information.
