As mentioned earlier, hydraulic systems have significantly more holding and locking power. The Bear-Loc’s capacity ranges up to 4 million pounds.

“Infinite position” means that the rod can be engaged by the lock in any position along its stroke and when locked, motion is impossible in any direction. Only the Bear-Loc offers all of these features: positive failsafe locking, infinite position, and an elegantly easy locking system to use and maintain.
Chances are, your processes require versatility in power holding and locking design. The Bear-Loc is available in a wide range of configurations, such as:
All are available in both Tie Rod and Mill Type constructions.
Backlash is clearance or motion in a mechanism caused by gaps between the parts. It’s sometimes called “lash” or “play.” If your processes require locking with zero backlash, make sure the system can deliver. The Bear-Loc features zero backlash.
As mentioned earlier, the Bear-Loc delivers no-motion reliability in any direction when engaged and operated within its rated capacity. That includes high system installations, in many industries and applications, from oil rigs to crash test walls, to inspection vehicles.
Wear in systems is caused by a variety of factors, both internal to the system (e.g. design, number of moving parts) and external (e.g. frequency of use, application). Be sure to check the manufacturer’s track record regarding leaks because locking systems can potentially leak fluids. Be certain to communicate the type of fluid your system uses. That knowledge informs seal type and lock capacity, and the Bear-Loc can be designed to assure smooth function without leaking.

Ask for specifics about longevity because locking systems have widely varying lifespans. Many Bear-Locs have been in active service for two, three or even four decades or more.
Of course, all things eventually wear to the point of requiring repair or replacement. Be certain that the manufacturer can effectively repair or replace your locking hydraulic system. You can entrust to York Precision’s expert team the repair or replacement of Bear-Locs, maintaining the consistently high standards you require, and have come to expect.
If you plan to spend just a few hundred dollars and are looking for an off-the-shelf product with a short lifespan, the Bear-Loc is not for you. We recommend doing a clear-eyed cost-benefit analysis: calculate both the return on investment over several decades (not merely years), and the cost to process and/or human life in the event of a system failure. We can attest to the fact that, in terms of system purchases, Bear-Loc customers consider it to be one of the best values of their careers.
The Bear-Loc’s unique patented design is comprised of a rod and liners enclosed in a sleeve which forms an interference fit with the outside diameter of the rod. This interference 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, removing the interference and creating enough clearance for the rod to be stroked with minimal resistance. Simply remove hydraulic pressure and the Bear-Loc locks automatically.
