Vibration Control

Our vibration control products are designed to address a wide range of vibration-related challenges. Whether it's reducing structural vibrations, damping machine vibrations, or isolating sensitive equipment, our solutions are tailored to meet the specific needs of your project. We utilize advanced technologies, materials, and engineering techniques to develop products that effectively mitigate vibrations, ensuring smoother operation, improved reliability, and extended lifespan of your assets.

Our extensive product lineup includes vibration isolators, shock mounts, vibration dampers, and vibration absorbers, among others. Each product is carefully designed and tested to provide optimal performance and long-term durability. We offer solutions for various industries, including manufacturing, aerospace, automotive, healthcare, and more, allowing you to find the right vibration control product for your specific application.

mountings

  • VMC Series R/RD neoprene isolators are molded in four sizes and can support up to 4000 lb. per isolator. They offer up to .5 inches of static deflection for excellent vibration isolation. All of our R/RD series isolators are molded completely in color for ease of identification, and all metal parts are completely embedded in neoprene for corrosion resistance. A tapped hole in the center of the mounting enables it to be securely bolted to the equipment. The mountings can also be furnished with a positioning pin (Series RP/RDP) for use with equipment that has inaccessible bolt holes

  • VMC Series AC Spring-Flex mountings are free standing and laterally stable spring mountings. The coils are designed with an excellent ratio between the coil O.D. and operating height insuring lateral stability. In all of our designs, this ratio is a minimum of 0.80 and many have approximately a 1 to 1 ration. In addition, our coils are designed with low operating stresses thus insuring a long operating life of the mounting. All of our open spring mounts have leveling capability and include a bolt hole in the bottom cup or a two hole rectangular baseplate for bolting to the structure. They are available with deflections up to 5 inches (127 mm) and are recommended for use directly under most HVAC equipment and in conjunction with structural steel bases and concrete inertia blocks.

spring hangers

  • VMC Series RSH Spring Flex hangers provide optimum vibration isolation for suspended piping and equipment. They incorporate a color coded steel spring in series with a neoprene rubber element. This combination is excellent for critical applications where it is important to isolate both vibration and structure-borne noise. Load ranges from 21 lb. to 5000 lb. and up to 5 inches of static deflection offer a wide variety of choices to insure proper support. Series RSH-30A offers all of the above features plus the capability for the lower hanger rod to swing approximately 30 to compensate for rod misalignment. The 30 misalignment capability insures that the rod does not short circuit the hanger by coming in contact with the hanger box.

  • To prevent load transfer to the equipment flanges when the piping system is filled, VMC has designed pre-positioning hangers which should be installed at the first three hanger locations adjacent to the equipment. Series RSHP incorporates a load bearing plate within the hanger box which keeps suspended piping at a fixed elevation during installation and start-up. Once the system is filled, the load is transferred from the plate to the spring insuring minimal movement in the piping. This design insures that the weight of the piping is kept off isolated equipment in order to maintain alignment, protect flexible connectors, and keep equipment isolators from becoming overloaded. Series RSHP is capable of supporting loads up to 5000 lbs. and offers up to 2 inches of static deflection.

restraints

  • Fabricated of welded steel components incorporating thick neoprene elastomer pads molded to Bridge Bearing quality specifications, the design of these restraints allows for the removal and replacement of the neoprene elements. These restraints are designed for a minimum of 1.0g accelerated force in all directions. Series SR for loads from 250 to 12,000 lbs.

  • VMC Series SCR Seismic Cable Restraints are recommended for use to restrain suspended piping, equipment, and ductwork during a seismic event. Our cable restraint kits are manufactured from 7 x 19 galvanized aircraft cable, and are available in 1/8”, 1/4”, and 3/8” diameters. One cable restraint kit consists of the following components: 2 cable lengths swaged at one end; 4- cable restrain angle brackets; 4-shackles; 4- cable clips; 2- thimbles

Pads

  • VMC’s Maxi-Flex Neoprene Pads are molded in standard size sheets 18”X18”X3/4” thick (457X457 X 19mm) consisting of 81-2” (51 mm) square segments. These segments are separated by a thin web that can easily be cut to fit required loading and shape of equipment base. They provide excellent high frequency sound attenuation and can be used effectively to prevent shock and vibration transmission in non-critical installations. Maxi-Flex Pads are available in four color coded loading types, which will satisfy a wide range of load/deflection requirements.

  • A resilient cross ribbed neoprene pad with an extremely high deflection rate. Alternately raised ribs, an exclusive VMC feature, provide effective vibration isolation in both high and low load ranges. May be used in multiple layers for greater deflection. Shear-Flex requires no bolting or cementing as gripping action of ribs prevents “walking”. Maximum capacity 120 psi. Standard size sheets 18”x18” x 3/8” and 18”x 36” x 3/8”.
