Your Home for BEAR-LOC® Locking Devices and Other High-Quality Products

BEAR-LOC® locking devices are the flagship of the York Precision product line. BEAR-LOC devices offer a safe and reliable solution for applications requiring infinite position locking, high system stiffness and zero backlash. The unique "positive" locking action only occurs when turning off the power, eliminating the possibility of workplace accidents.

The patented BEAR-LOC® design adheres to the principle of elastic expansion of metal under pressure, contributing to their dependability and simplicity. They're also extremely durable to last for decades.

As a leading precision machining and hydraulics manufacturer, we also offer additional products such as:

  • Hydraulic cylinders and actuators: We produce high-performing, solidly constructed double- or single-acting and spring-loaded hydraulic cylinders made from quality materials such as steel, aluminum and stainless steel. They're available in an assortment of bore sizes and pressure capacities, and they comply with stringent quality control and testing procedures.
  • Industrial/piston accumulators: We also offer a selection of accumulators in a variety of sizes and pressure capacities. Key features include safety vents that warn of internal pressurization, dual outboard wear strips that prevent piston rubbing and a T-seal with dual backup rings that ensure separation and minimize drag. 

Our advanced custom hydraulic component machining capabilities enable us to manufacture any of our products to your exact specifications. We're experts at designing, engineering, prototyping and testing products that will meet and exceed your performance and quality expectations.
