iglidur® J, polysorb disc spring

What are the advantages of iglidur® polysorb disc springs?

Our polysorb disc springs are made of iglidur® materials, which offer various advantages:

• Lubrication-free and maintenance-free thanks to solid lubricants contained in the material
• Resistant to a wide range of chemicals and media
• Low humidity absorption
• Cost-effective

 

 

When should I use iglidur® polysorb disc springs?

• If flat spring characteristics are required, which are only possible in metal at considerable expense (slotted versions)
• For compensation of axial clearances and manufacturing tolerances
• For vibration dampening
• For noise reduction
• If a non-magnetic material is required
• For electrical and thermal insulation

 

When should I not use iglidur® polysorb disc springs?

• When constant spring forces are necessary over a wide temperature range
• When high spring forces are required

 

What is a disc spring?

Disc springs are flat, conical washers that can be elastically deformed. They are used in designs that have a short spring travel. Due to their disc-shaped design, they can absorb high loads and only deform slightly. They are used when a high force is to be exerted on a small area or when a large spring force is required with a small spring travel.

 

The functions of a disc spring

They are an integral part of many machines and devices. They play a crucial role in absorbing and storing mechanical energy. When a force acts on the disc spring, it deforms and stores energy in the form of tension. When the force is removed, it releases the stored energy and returns to its original shape. It can be used alone or in a stack with other disc springs to achieve the desired spring force and spring characteristic curve.

 

The different areas of application of disc springs

Disc springs are used in the automotive industry, among others, where they are used in clutch and brake systems. In mechanical engineering, they are used in CNC machines, for example, where they provide constant force to fasten workpieces in the chuck. They are also used in electrical engineering. Here they are used in electrical switches and relays, for example.

 

iglidur polysorb disc springs comply with DIN 2093 or EN 16983

DIN 2093 has been replaced by a European standard EN 16983, which is identical in content. This standard specifies the quality requirements and dimensions for disc springs. iglidur polysorb disc springs comply with EN 16983 (formerly DIN 2093).
