Vibro-Leveler Machine Mounts


The Bushings Inc. Vibro-Leveler is a dual purpose, rubber-in-shear machine mount that suppresses the transmission of vibration and noise, and allows precision leveling of your machines.

Vibro-Leveler Mounts:

  • Protect Industrial Machinery and Buildings from the Potentially Damaging Effects of Vibration and ShockMachine Mounts
  • Install Quickly and Easily
  • Require No Special Parts or Maintenance
  • Provide Precision Leveling Capability
  • Fail - Safe Design
  • Environmentally Friendly - Reduce Fatigue Related to Workshop Noise, Vibration and Shock
  • Come Complete, Require No Tapping or Fitting

Simple in design, and rugged in construction, each Vibro-Leveler has an inner cylinder with attached stud, which is insulated from the outer shell by a wall of mechanically bonded rubber.

Safe and Smooth Operation

Ten shelf-standard sizes can meet your specific requirements. Available in capacities from 10 to 1,000 pounds, Vibro-levelers provide an ample safety margin.  Even when overloaded to destruction, they only permit a drop of less than one-half inch.

Bushings, Inc. recommends Vibro-Levelers both for new and existing machines.  Typical applications include printing equipment, enclosure systems, blowers, compressors, punch presses, vacuum pumps, hydraulic presses, jig borers, screw machines, snag grinders, offset press systems, and testing equipment.


Usually, Vibro-Leveler are installed under a machine. Simply raise or tilt the machine to allow a "Vibro-Leveler" to be slipped under the base.  Insert its stud into the hold-down bolthole in the base of the machine. To level the machine, adjust the lower nut upwards to hold the machine on an even plane, then lock the upper nut down to hold the machine in position.  The Vibro-Levelers come complete including the leveling and locking nuts; no fitting, cutting, or threading of any kind is required. Where the machine must be kept at or near its original level, brackets are either bolted or welded to the side of the base. Ordinary structural brackets are ideal for this.  Though seldom required, hold down boltholes in the base of each mount permits securing to the floor.

While a typical installation requires four Vibro-Levelers, any number may be used to accommodate machinery requiring more (or fewer) points of suspension.  Once the total weight of the machine is established, refer to the accompanying specification table to determine the correct mounting number(s) based on their weight bearing capacities.  The combined capacity of the number of mountings should equal or exceed the total weight of the machine to be supported. For example, if the machine weighs a total of 700 lbs. and mounts are to be positioned in a four point suspension pattern, each point supports 175 lbs., and four 200 lb. Vibro-Levelers (mounting number 3200) should be used.

If the machine to be supported is not symmetrical so that there would be considerably more weight on one end than the other, the mountings on the heavier end must be of correspondingly greater capacity.

Latest from our FAQ

  • Troubleshooting Rubber Insulated Bushing Performance Problems

    Back in early 2013, we received a phone call from a large OEM experiencing early wear out problems with the rubber-insulated bushings in their shaker machines.  This was a very severe application with each of the three bushings in the machine, seeing continuous, radial, torsional, and conical loading.

  • Rubber Insulated Bushings and Method of Manufacture

    One of the most frequently asked questions we receive from customers who visit us on line, or call in - is with regards to bushing design, and specifically – What method of manufacture is best for my bushing application?  In this blog, we’ll examine two different approaches to bushing manufacturing design.

What Our Clients Say About Us

Testimonial Image
"I want to take this opportunity to thank the Bushings Incorporated team that recently helped us get our automated assembly line up and running.  For years our line required our rubber insulated overmolds be manually inserted due to several failed attempts to get an automated press to properly insert the bushings.  The Bushings Incorporated team was able to help by working with our manufacturing engineers to develop fixtures, and procedures that were able to get the automated press up and running.

With the new press up and running, the consistency has been great, and the operator is very happy with the new process.  The operator says that the new press and fixturing is doing a good job at installing the bushings straight and consistent.  He has experienced no “mushrooming” or tearing of the bushings with the automated press (this was the reason for manually inserting them for so many years).  The operator also says that the job is much easier on him, and the production level is up due to the new process.

The help that was received to improve our process was above and beyond.  That kind of support is needed and appreciated, and while most vendors lack in their support, it is my feeling that Bushings Incorporated and their team have gone one step above.

Thanks again for the support!"
