SKF Vibracon chocks are our permanent, strong and re-usable machinery mounting chocks for all types of rotating or critically aligned machinery. Using SKF Vibracon chocks is the most economical way to establish a perfect mounting plane. As SKF Vibracon mounts are mechanically stiff chocks, accurate mounting is made simple and quick.

  • Absence of curing time
  • Eliminates the trial and error alignment process
  • Adjustability during the life cycle of the machinery

SKF Vibracon chocks are a fast and safe way to chock your new-builds as well as repairs. This is supported by a type approval from all major classification societies, as well as approval of use by the US Navy.

The Original
SKF Vibracon chocks are machinery mounting chocks that are easily and accurately adjusted. The chocks accommodate up to a 4° angular difference between machine and the mounting base without expensive machining of the base or extra work of installing epoxy resin chocks. The self levelling capability combined with the height adjustment feature eliminates the possibility of a soft foot in the production line.

The Low Profile
The Low Profile chocks offer an economic solution for repair projects or fixed design systems where expensive milled chocks, shims or epoxy resins were applied. The SKF Vibracon Low Profile configuration addresses those applications where the chock height between the foundation and component has been established by the previous design. A variety of adjustment tools for confined installation spaces are available.
