What advantages do iglide Polysorb disc springs have?
Our Polysorb disc springs are made from iglide® materials, which have various advantages:

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

iglide® J material | The endurance runner at higher temperatures in the food industry
Products made from iglide® J are characterized above all by their lowest friction values in dry-running applications, and their very low tendency to stick-slip. With a maximum surface pressure of 35 MPa, iglide® J plain bearings are not suitable for extreme loads.

 

When do I use iglide® polysorb disc springs?	When should I not use iglide® polsorb disc springs?
When flat spring characteristics are required, which are only possible with considerable effort (slotted versions) with metal	When constant spring forces are required over wide temperature ranges
When compensating for axial play and manufacturing tolerances	If high spring forces are desired
With vibration compensation
With noise reduction
If an antimagnetic material is desired
For electrical and thermal insulation

When do I use iglide® J?

• At high speeds
• When maximum wear resistance is sought at low to medium pressure loads
• When lowest wear is desired with a variety of different shafts
• If low friction values are desired in dry running
• If the bearing is supposed to be vibration-damping
• When good material resistance is required
• Best behavior in soft waves
• Low moisture absorption

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


The functions of a disc spring
Disc springs 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 decreases, the disc spring releases the stored energy and returns to its original shape. A disc spring can be used alone or in a stack with other disc springs to achieve the desired spring force and spring characteristic.

The various areas of application for disc springs
Disc springs are used, among other things, in the automotive industry, where they are used in clutch and brake systems. In mechanical engineering, for example, they are used in CNC machining and ensure constant force to fasten workpieces in the chuck. Disc springs are also used in electrical engineering. Here theya re used, for example, in electrical switches and relays.


iglide® Polysorb disc springs meet DIN 2093 or EN 16983
DIN 2093 has been replaced by a European standard EN 16983 with identical content. This standard specifies the quality requirements and dimensions for disc springs. iglide Polysorb springs meet EN 16983 (formerly DIN 2093).
