springs - Elastomer coil springs

STRACK NORMA elastomer springs are specified in the DIN Standards 9835 and are offered in two different grades of elastomers.

SN 2625- spring grade on the basis of
Chloropene rubber (CR).

SN 2600- heat treated Polyurethane elastomer
(PUR) dynamic high loading capacity.
With these two grades of material the limitations in respect of their degree of deflection, stroke length,load absorption and temperature range are fully
exploited and aligned.

Behaviour in relation to temperature
The temperature range is between –20 °C and +80 °C. Temperatures of –40 °C to +120 °C of short duration are permissible. The governing factores are
self generated and ambient temperatures.
