1. Min ID of spring - 25mm
2. Max ID of spring - 300mm
3. Min and Max OD will depend on bar dia, which will be calculated -
ID + 2 x bar dia = OD
4. In our brochure we have written bar dia range as 14mm to 40mm,
but during manufacturing it will be 6mm to 40mm
5. Min rod length - 1500mm
6. Max rod length - 4800mm
7. Max free height of the spring without load - 1000mm
8. Max height with full load and spring load parameters will be calculated
as per bar dia.
