What is the SE126 anti-vibration mounting?
The Hutchinson Paulstra SE126 range includes the V1H751 and V1H752 metal mountings, designed for the vibration isolation of stationary or on-board equipment subjected to high loads.
They consist of a pressed steel housing and base, a light-alloy shaft and a stainless steel wire mesh cushion providing the resilient function. The steel parts are protected by paint.
- Natural frequency: from 15 to 25 Hz.
- Static load: up to 1,000 daN depending on the reference.
- Resilient element: stainless steel wire mesh cushion.
- Operating temperature: from -70 °C to +300 °C.
- Applications: stationary or on-board.
- Manufactured in: France.
What are the advantages of the SE126?
✅ Good resistance to horizontal loads: reinforced versions feature radial cushions capable of withstanding high dynamic loads.
✅ On-board applications: suitable for equipment installed on ships, vehicles, railway equipment and construction machinery.
✅ High loads: up to 1,000 daN axial static load depending on the reference.
✅ Wide temperature range: suitable for use from -70 °C to +300 °C.
✅ High mechanical strength: up to 10 g in compression at maximum load for the V1H752 family.
✅ Floor fixing: also suitable for stationary machinery requiring secure installation.
What applications is the SE126 suitable for?
Paulstra particularly recommends the V1H751 and V1H752 for on-board equipment in the marine, railway, road transport and construction sectors, as well as for engines, pumps, generator sets and piping. They can also be used on stationary machinery requiring floor fixing.
What is the difference between the SE126 versions?
The range includes two main sizes, V1H751 and V1H752, with different load capacities and radial load resistance.

Key point: the -11 and -12 versions provide higher radial load capacity thanks to their reinforcing cushions. For example, the V1H752-11 can withstand up to 3,000 daN radially, compared with 1,000 daN for the V1H752-01.
What are the technical characteristics of the SE126?
- Maximum amplitude at resonance: ± 0.4 mm.
- Amplification factor at resonance: below 4.
- V1H751 structural resistance: 5 g in compression at maximum load.
- V1H752 structural resistance: 10 g in compression at maximum load.
- Operating temperature: -70 °C to +300 °C.
- V1H751 weight: 0.75 kg.
- V1H752 weight: 1.6 kg.
How to choose your SE126 mounting?
Start by determining the load supported by each mounting, then check the dynamic compression, tension and radial loads.
- V1H751-01 / -11: loads from 70 to 250 daN.
- V1H751-02 / -12: loads from 150 to 500 daN.
- V1H752-01 / -11: loads from 300 to 1,000 daN.
- Choose the -11 or -12 versions when horizontal loads are significant.
Price on request: please provide the load per mounting, the number of mountings and the dynamic loads of your installation so that we can determine the suitable reference.
