Material: 65Mn Spring Steel

Colour: Yellow, Blue, Red, Green, Brown

Size: Outer Diameter x Inner Diameter 40x20mm

Length: 40-300mm

Compression Rate:

• Yellow - TF (Extra Light Load): can be compressed 50%
  
• Blue - TL (Light Load): can be compressed 40%
  
• Red - TM (Medium Load): can be compressed 32%
  
• Green - TH (Heavy Load): can be compressed 24%
  
• Brown - TB (Super Heavy Load): can be compressed 20%

Formula: Ultimate pressure ÷ (free length x compression rate) = force generated per millimeter of compression
Example: Red, OD is 40mm, free length is 100mm,256kg ÷ (100mm × 32%) = 8kg/mm
