SE129 MOUNTINGS

What is the SE129 anti-vibration mounting?

The Hutchinson Paulstra SE129 is a metal shock absorber designed for the vibration isolation of heavy industrial equipment.

It consists of a stack of two or three stainless steel wire mesh cushions. The number of cushions makes it possible to vary the natural frequency of the mounting and therefore adapt the level of vibration attenuation.

The conical shape of the cushions also allows the mounting to withstand radial loads while maintaining good stability of the suspended equipment.

• Natural frequency: from 10 to 16 Hz depending on the reference.
• Permissible load: up to 28,000 daN.
• Resilient element: stainless steel wire mesh cushions.
• Loads supported: axial and radial.
• Applications: heavy industrial equipment.
• Manufactured in: France.

What are the advantages of the SE129?

✅ Very high load capacity: up to 28,000 daN depending on the reference.

✅ Adjustable natural frequency: the stack of metal cushions provides a natural frequency between 10 and 16 Hz.

✅ Good radial load resistance: the conical metal cushions can withstand transverse loads.

✅ Equipment stability: the mounting design helps limit unwanted movement of the suspended mass.

✅ All-metal construction: suitable for heavy industrial applications.

What applications is the SE129 suitable for?

Paulstra recommends the SE129 for cutting and metal-forming machinery such as presses, punching machines and stamping machines, as well as for heavy-duty rotating machinery.

How does the SE129 mounting work?

The SE129 uses several stacked conical metal cushions. The stack configuration changes the flexibility of the suspension and therefore its natural frequency.

SE129 mounting dimensions

The range includes two main formats corresponding to the SP539-882 / SP539-883 and SP539-887 / SP539-888 families. The diagram shows the dimensions, threads and fixing points for each configuration.

SE129 references and performance

Four references cover loads ranging from 500 to 28,000 daN.

How to choose your SE129 mounting?

Selection mainly depends on the load supported by each mounting and the required natural frequency.

• SP539-882 / SP539-883: for loads between 500 and 14,000 daN.
• SP539-887 / SP539-888: for loads between 1,000 and 28,000 daN.
• The 882 and 887 versions operate between 12 and 16 Hz.
• The 883 and 888 versions provide lower natural frequencies between 10 and 13 Hz.
