BEAR-LOC® - Locking Device

BEAR-LOC® is a simple, reliable locking device which can be used 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.

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
• Overload Protection
• Versatility
• Economy

BEAR-LOC® Operating Principle
The BEAR-LOC® Section is comprised of a cylinder rod and liners enclosed in a sleeve which forms an interference fit with the outside diameter of the rod. This fit provides a positive mechanical connection to lock the rod in any phase of the stroke. As soon as hydraulic pressure is applied the sleeve expands radially within the elastic limits, relieving the interference and creating enough clearance for the rod to be stroked with minimal resistance. Simply removing the hydraulic pressure via the unlock port allows the BEAR-LOC to re-engage automatically. Thus even with accidental lock pressure loss, the BEAR-LOC offers totally automated operation.

BEAR-LOC® units can be supplied in a wide variety of configurations. Call, Fax or email the Sales/Engineering Department today for additional information or to discuss your special applications.
