How to choose Compression Coil Springs

Points to check when selecting, with the values for this product (99-00〜99-35).

1. 1. Select by required load and spring rate

   The spring rate is the load required to deflect the spring by 1 mm. Multiplying the difference between installed and operating length by the spring rate gives the estimated load generated. Check whether the target load can be achieved within that deflection range, and narrow down candidates by spring rate value.

2. 2. Outside or inside diameter to fit the bore or shaft

   Check the outside diameter when the spring fits into a bore, and the inside diameter when it fits over a shaft. Because the coil diameter slightly increases under compression, allow clearance to the bore or shaft. The outside diameters of the listed products range from 3 to 11 mm.

3. 3. Match free length to installation space

   Free length is the length under no load. The difference from the installed length is the initial deflection, which determines the preload force. Slender springs are prone to buckling (bending sideways), so also consider whether a guide rod or guide bore is needed.

4. 4. Do not exceed maximum allowable deflection and load

   Confirm that the maximum operating stroke stays within the maximum allowable deflection and does not reach solid height. Using the spring beyond the allowable value can cause set (permanent deformation) or fatigue failure. Allow a margin in applications with repeated operation.

5. 5. Choose material to suit the environment

   This product: Material SUS304

   SUS304WPB offers corrosion resistance and, in the listed examples, can be used at -30 to +200 °C. Piano wire and oil-tempered wire suit applications that benefit from high strength, but they rust easily, so check whether surface treatment or rust prevention is required.

6. 6. End shape that affects seating

   Springs with ground ends have flat seating surfaces, so the load acts straight along the axis and the spring is less likely to tilt. For applications such as dies and jigs that require stable posture, check whether grinding is specified.
