Vibration and Shock Isolation Solutions Since 1964

MXL & MXLP Isolators and Press Mounts (See Video)

Vibro/Dynamics MXL & MXLP Series Micro/Level Isolators are designed for the free-standing support of large stamping presses weighing from 113 to over 2270 metric tons. (250,000 to over 5 million lbs.). 

Isolator dynamic natural frequencies as low as 8 Hz can be achieved, resulting in very effective vibration and shock isolation. This innovative patented design combines multiple layer elastomer technology with our popular Hydra/Level® hydraulic lift-assist feature. 

MXL Isolators have a vertical leveling screw located in the center of the mount. The leveling screw pass through the mounting hole in the machine foot. Leveling is accomplished by turning the leveling screw into and out of the isolator housing.

Hydraulic Cylinders can be located within the MXL Isolator to make leveling and alignment faster, safer and easier. See Hydra/Level Feature.

Isolators have a Precision Leveling and Swiveling Mechanism. Leveling is accomplished by turning the larger diameter leveling boss. This design can be located anywhere under a machine foot.

The HYDRA/LEVEL® Feature
(See Large Press Video)

leveling mountHydra/Level® is a patented hydraulic lift-assist system available in Vibro/Dynamics Micro/Level MX Press Mounts. Hydraulic Cylinders can be placed, permanently or temporarily, into isolator corner pockets making leveling and aligning even the heaviest machinery faster and easier, especially when aligning transfer press rolling bolster rails.

No separate jacks or cribbing are necessary. Installation times are greatly reduced by several days. In an actual Hydra/Level installation, a machine weighing up to 4,500,000 pounds was leveled and aligned in less than half a day. 

For MXL and MXLP Models, when the Hydraulic Cylinders are activated, the load on the precision leveling screw is reduced until it can be adjusted by hand. Precision leveling adjustments are made in this manner. The process is repeated until the machine is perfectly leveled and aligned and the support is Fine/Tuned.

For MXBP and MXBN Models, when the Hydraulic Cylinders are activated, the machine foot is lifted off the top of the Isolators, allowing the insertion of Shim Materials. The process is repeated until the machine is perfectly leveled and aligned and the support is Fine/Tuned.

Machine Base is initially installed on Isolators with Hydra/Level capability.


Hydra/Level Isolators are then connected to a hydraulic pump.


Cylinders are engaged to lift lowest foot, relieving the load so that the leveling screw can be easily adjusted or shims inserted.

Cylinders are backed off, the level checked, and the system disconnected if leveling and elevation adjustments are completed.
