SE125 MOUNTINGS

What is the SE125 anti-vibration mounting?

The Hutchinson Paulstra SE125 range includes the V118-MG, V118-DG, V318 and V318-D metal shock absorbers, designed to provide vibration isolation and shock protection for heavy industrial equipment.

They consist of a painted cast iron upper cup and base with four fixing holes and a tapped shaft. The resilient elements consist of stainless steel wire mesh cushions.

• Natural frequency: from 11 to 22 Hz depending on the version.
• Load range: up to 7,000 daN.
• Resilient elements: stainless steel wire mesh cushions.
• Operating temperature: from -70 °C to +300 °C.
• Fixing: 4 holes in the base + central tapped hole.
• Manufactured in: France.

What are the advantages of the SE125?

✅ High load capacity: up to 7,000 daN depending on the family.

✅ Vibration isolation and shock protection: the metal cushions provide vibration isolation while withstanding high loads.

✅ Anti-rebound function: particularly suitable for stationary or on-board applications.

✅ More flexible versions: the V118-DG and V318-D use three metal cushions to reduce stiffness.

✅ Suitable for severe environments: operation possible between -70 °C and +300 °C.

✅ Stationary and mobile applications: industrial machinery, engines, pumps, generator sets and on-board equipment.

What applications is the SE125 suitable for?

Paulstra particularly recommends this range for machine tools, grinders, presses, rotating machinery, engines, generator sets, pumps and equipment subjected to demanding operating conditions. The DG and D versions are suitable for machines operating above 2,000 rpm, compared with 2,500 rpm for the MG and V318 versions.

What is the difference between the SE125 versions?

SE125 mounting dimensions

Dimensions differ between the V118 and V318 families, as well as between the standard versions and the three-cushion versions.

SE125 loads and performance

How to choose your SE125 mounting?

Selection depends on the load supported by each mounting, the required natural frequency and the dynamic loads to which the equipment may be subjected.

• V118-MG: 50 to 900 daN, natural frequency from 16 to 22 Hz.
• V118-DG: same load range with a lower natural frequency of 11 to 17 Hz.
• V318: 250 to 7,000 daN, natural frequency from 16 to 22 Hz.
• V318-D: same load range with a lower natural frequency of 11 to 17 Hz.
