When should I use Polysorb disc springs?
When an application requires special disc spring characteristic curves which are flat and possible in metal only at a considerable expense (slotted designs)
For compensation of axial clearances and manufacturing tolerances
For vibration damping
For noise damping
When a non-magnetic material is required
For electrical and thermal insulation
When not to use polysorb disk springs?
When constant spring forces are necessary over a wide temperature range
When high spring forces are required
