Power Springs
At each of these diameters length is available from 100mm to 100m with a length tolerance of -/+ 1% or 5mm. PowerSprings can be specified in a similar way to a steel extension spring. A typical specification chart is shown in the table.
A range of stainless steel and aluminium end fittings are used as standard, but customised end options can be fitted to meet application demands. Additionally for special requirements, to meet British Standard 3F70:1991 for example, or when high performance is required, different fibre sheathing cover materials can be used.
