SE121 MOUNTINGS

What is the SE121 anti-vibration mounting?

The Hutchinson Paulstra SE121 is an adjustable metal anti-vibration mounting designed primarily for machine tools and industrial equipment.

The standard version consists of a spheroidal graphite cast iron cup combined with a stainless steel wire mesh cushion providing the resilient function.

• Natural frequency: from 15 to 30 Hz depending on the version.
• Static load: up to 5,000 daN depending on the size.
• Resilient element: stainless steel wire mesh cushion.
• Adjustable versions: H and WH models with levelling screw.
• Manufactured in: France.

What are the advantages of the SE121?

✅ Levelling adjustment: H and WH versions feature a levelling screw allowing the machine height to be adjusted.

✅ Suitable for demanding industrial environments: the metal cushion is resistant to oils, temperature and fatigue.

✅ Two levels of flexibility: standard version or W version with a thicker metal cushion.

✅ Wide load range: from 50 to 5,000 daN depending on the size.

✅ Long service life: the metal suspension is designed for durable use with industrial equipment.

What is the difference between the SE121, H, W and WH versions?

The W version uses a thicker metal cushion to provide lower stiffness and improved vibration attenuation.

What applications is the SE121 suitable for?

The standard versions are particularly suitable for machine tools using material removal processes. The more flexible W versions are particularly suitable for equipment operating through material deformation, such as presses, shears and bending machines.

SE121 references and performance

The current range includes 16 references. Each size is available in standard, H, W and WH versions.

SE121 mounting dimensions

The dimensions of the SE121 vary depending on the mounting size and whether or not the H adjustment system is fitted. The diagrams below identify the different dimensions used in the table.

Standard and W versions

H and WH versions with levelling screw

The H and WH versions feature a levelling screw allowing the machine height to be adjusted.

Detailed dimensions D1, H1, D2, H2, M, C, H3, d1, d2 and P are available in the technical data sheet.

How to choose your SE121 mounting?

Start by determining the load supported by each mounting in order to select size V43, V44, V45 or V46.

• Choose a standard version for a natural frequency of 22 to 30 Hz.
• Choose a W version for a more flexible suspension, with a natural frequency of 15 to 22 Hz.
• Add the H suffix when a levelling adjustment using a levelling screw is required.
