 Vibracon® SM Low Profile

 Products
Vibracon® SM Elements provide an ideal foundation for machinery allowing for the quickest, easiest and most accurate fixed machinery installation possible.

Use of Vibracon® SM Elements avoids machining of foundations in many cases. The spherical top accommodates deviations in mounting surfaces. This, combined with height adjustment capability, eliminates the possibility of a soft foot problem. The installation of Vibracon® SM Elements is recommended for all machinery where alignment is critical. The elements have been installed in rugged marine propulsion environments all the way through to industrial and packaged unit applications.
Whether in combination with fabricated foundations or sole plates on concrete, the installation of Vibracon® SM Elements represents economic savings from the start by the elimination of the mounting cost variable in life-cycle expenses. The Vibracon® SM Elements have received approval from: classification societies, equipment manufactures and the US Navy. Engineering support for specific needs, non-standard applications or installation training are available.


Recommended minimum clamping length (B) for all types of machinery is 150 mm.
This in combination with the bolt torque from the table below, results in a bolt stretch of 0.2 mm.

Vibracon SM elements are produced of Fe 52.3 or, if required, stainless steel AISI 316L (1.4404).
