PA diaphragm spring complete

Bellows spring with special geometric advantages. This results in a constant pressure on the moving bellows plate. With flat installation, an additional increase in pressure can be achieved.

Plates and guide parts made of aluminum. The external dimensions in installed condition are approx. 200 mm length and 100 mm width. The height at rest is between 65 and 120 mm, depending on the required mode of operation. At 70 mm spring bar distance from the wind-filled bellows plate, the spring achieves approx. 80 N pressure.

Delivery individually or cheaper from 10 pieces.

New available from 2013: Set of 2 spring extensions Sometimes it seems useful to make the standard parallel spring stronger with additional coil springs. The 100 mm wide plates still offer space to the right and left of the central coil spring. However, care must be taken that the overall stability is not exceeded by the extension. The set of 2 consists of 2 spiral tension springs and retaining parts including wing nuts. The necessary drillings must still be made on the standard spring.
