SE111 MOUNTINGS

What is the Radiaflex SE111 anti-vibration mounting?

The Hutchinson Paulstra Radiaflex SE111 is a rubber anti-vibration mounting consisting of cylindrical metal plates and bonded natural rubber. Its design provides greater radial flexibility than axial flexibility.

Depending on the installation configuration, the rubber operates in compression in the axial direction, shear in the radial direction or compression-shear. This versatility makes the Radiaflex suitable for a wide variety of vibration isolation configurations.

• Metal parts: cylindrical metal plates.
• Elastomer: bonded natural rubber.
• Fixings: threaded studs, tapped holes or mixed fixing depending on the reference.
• Operating temperature: -20 °C to +70 °C.

What are the advantages of the Radiaflex?

✅ Versatile installation: several fixing configurations allow the mounting to be adapted to the machine and its supporting structure.

✅ Simple and economical solution: a proven range suitable for many vibration isolation applications.

✅ Wide choice of references: numerous diameters, heights, load capacities and fixing types are available.

✅ Multidirectional operation: compression, shear or a combination of both depending on the installation.

What applications is the Radiaflex suitable for?

The Radiaflex is designed to protect machines and structures against vibration. It can notably be used beneath thermal, electrical, hydraulic or pneumatic machinery, electrical cabinets, ventilation systems, air-conditioning units, generator sets, pumps, hoppers or floating floors.

How does the Radiaflex mounting work?

The choice of installation configuration makes it possible to use the properties of the rubber according to the direction of the applied loads. Under axial compression, the mounting supports the vertical load. Under radial shear, its greater flexibility can be used for vibration isolation, provided that the permissible loads of the selected reference are respected.

The Radiaflex can also operate in compression-shear when the installation combines loads in several directions.

What fixing configurations are available for the Radiaflex SE111?

The Radiaflex SE111 range is available with several fixing types. The diagrams below allow you to quickly identify your configuration and the dimensions to look for in the technical data sheet.

Where can you find the Radiaflex SE111 dimensions and references?

Radiaflex dimensions vary according to the mounting diameter, height and fixing type.

The letters shown on the diagrams above, such as ØA, B, C, D, G, H or S depending on the version, correspond directly to the dimensions shown in the Hutchinson Paulstra technical data sheet tables.

The Radiaflex range includes a large number of references. To keep this page easy to read, not all dimensions are reproduced directly here. The SE111 technical data sheet is the reference document for finding the exact dimensions, loads and performance of each model.

Radiaflex SE111 technical characteristics

The range includes versions with threaded studs, tapped holes, mixed fixing, certain 430 stainless steel references, as well as Diabolo mounts.

Dimensions, permissible loads and performance vary depending on the selected reference.

How to install a Radiaflex mounting?

For the fixing holes, provide an entry chamfer with a height equal to the pitch of the threaded stud.

Fixing by welding is strongly discouraged.

How to choose your Radiaflex reference?

The choice of a Radiaflex mounting mainly depends on the fixing method, available dimensions, load to be supported and the required behaviour in compression or shear.

Start by identifying your configuration using the diagrams shown above. Then refer to the corresponding table in the SE111 technical data sheet to compare the references compatible with your installation.
