Nitinol Micro Springs

Nitinol Micro Springs

KRL micro springs are the smallest nitinol springs--and the lightest actuators available anywhere!  So, if you're looking to build something small, KRL is the place to go!

Spring mandrel sizes (spring inner diameter) equal to or less than 3.2mm are defined as Micro springs.  The listing price is for per 5mm.  If multiple orders are made, a continuous length will be sent out unless said otherwise in the comments box. 

 

For bigger Springs, please check "Helical Spring" listings.
