5. Marking method
Mark it with the dimension of installation groove as below:
FSXL “Rod Diameter d” × “Groove Diameter D” × “Foot Diameter D1” × “Groove Width L” (Foot Height H1”)- “Spring material and shape”
For example: FSXL160×170×177.5×7.1(2.05)-316O meansdimensions d=160, D=170, D1=177.5, L=7.1, H1=2.05, Spring material 316, O shape
