What is the BECA SE117 mounting?
The Paulstra BECA SE117 anti-vibration mounting comprises two flat, parallel metal plates bonded together by a rubber ring.
With a natural frequency ranging from 8 to 14 Hz, it is designed for the vibration isolation of stationary rotating machinery while offering a particularly low profile.
- Upper plate: clearance hole or tapped hole with welded nut.
- Lower plate: lug mounting or direct floor installation.
- Bonded rubber with a dome-shaped ring.
- Bead or anti-slip base depending on the configuration.
- Removable protective cap: protects the rubber and distributes the load.
How does the BECA mounting work?
- Transverse elasticity close to axial elasticity: the BECA is an equi-frequency mounting.
- The rubber works mainly in compression.
- A progressive bump-stop effect protects the installation in the event of impact or accidental overload.
- The lower pad or bead provides an anti-slip effect.
What are the advantages of the BECA mounting?
✅ Low profile: a compact solution when the available space beneath the machine is limited.
✅ Quick installation: some versions can be installed directly on the floor and make it easier to move the suspended assembly.
✅ Wide load range: 3 rubber hardnesses and several diameters make it possible to adapt the mounting to the installation.
✅ 3 mounting configurations: base pad, lugs with clearance hole or lugs with tapped hole.
What applications is the BECA mounting suitable for?
The BECA SE117 is suitable for stationary rotating machinery and a wide range of industrial equipment, including electrical cabinets, grinders, air-conditioning systems, compressors, generator sets, laboratory equipment, pumps and transformers.
How to choose your BECA SE117 mounting?
The choice depends on the load per mounting, diameter, rubber hardness and required mounting method.
- Figure A: BECA with base pad for direct installation.
- Figure B: BECA with lugs and clearance hole.
- Figure C: BECA with lugs and tapped hole.
- Hardness: 45, 60 or 75 Shore A depending on the dimensions and required load.
What precautions should be taken during installation?
Connections between the machine and external equipment must remain flexible to prevent them from short-circuiting the anti-vibration suspension.
The BECA is recommended for stationary rotating machinery without significant unbalance. If significant unbalance is present, an inertia base may be required.
What are the dimensions of the BECA SE117 mounting?
The three mounting configurations are shown below. The table can then be used to identify the dimensions corresponding to each reference.

How does the axial compression load of the BECA mounting vary?
The load/deflection curves show the behaviour of the mounting according to its diameter and rubber hardness.

What mounting arrangements are possible with the BECA?
The BECA can be installed with a preloaded rebound limiter, using either a tapped-hole or clearance-hole version. The mountings can also be installed in a stacked arrangement to double the suspension deflection.
