1 /// Geometry

Diameter of brush or other limited design space preferably with tolerance

Diameter of shaft or other limited design space preferably with tolerance

2 /// Operational demands

Length of spring in pre-stressed state

Load of spring according to deflection L1; necessary if important for operation

Length of spring after stroke was carried out

Load of spring to deflection L2; necessary if important for operation

3 /// End Use

- description of unit where the spring will work; i.e. clamping unit, vehicle, press, valve, medical/military application - description of spring function: i.e. returning spring in hydraulic cylinder, counterweight for carriages, prioritize of load or deflection, guidance of shaft or brush, applied load until solid length, - please attach drafts of the spring usage

4 /// Specific demands

Possible affecting environmental influences?

affecting anvironmental influences could be high humidity, salts, acids, alkaline solution or other materials
