SKF Vibracon – The universal adjustable re-useable chock

SKF Vibracon is a machinery mounting chock that is easily and accurately adjusted. The chock accommodates the angular difference, up to 4°, between machine and the mounting base without expensive machining of the base or the 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 throughout the life cycle of the machinery.

Saves installation time

Re-adjustable / re-useable

Accommodates angular gaps

Self levelling

Eliminates the ‘Soft Foot’

Installed base of over 1 300 000 pieces

Standard range available from stock

Customized engineered solutions 

The SKF Vibracon is available in different materials to meet the need of your application, even those in the harshest environments. This adjustable chock is available in standard carbon steel (CS series) and in surface-treated carbon steel (CSTR series) for improved corrosion protection. Developed to withstand the most challenging conditions, a stainless steel version (SS series) is offered with the highest corrosion protection available. SKF Vibracon low profile (ASTR series) configuration addresses those applications where the chock height between the foundation and component has been established by the previous design.

Applications and industries

The origin of the SKF Vibracon chock products can be found in a marine environment. However, the product is applied in many more industries. When components are pre-mounted on a steel base frame, a so called skid, the necessity for initial and final alignment is apparent. Also for concrete mounted components. The Vibracon does have an impressive track record.
