Find your compression springs at The Spring Store where we offer a broad range of compression spring sizes in various material types such as music wire (spring steel), hard drawn, stainless steel, oil tempered, beryllium copper, and phosphor bronze.
Extension Springs are organized in order of increasing diameter and wire size. Note that in each category the spring rate decreases as the length increases. After identifying the proper outside diameter of the spring needed, select a range for wire diameter and free length. The broader the range of values selected the more options will be offered.
Constant force springs are a variety of extension springs. A strip of steel with a preset curvature is coiled tightly so that each turn of the strip rests on its inner neighbor. The spring is actuated in a pulling, linear motion with the deflection resistance originating from the material's stiffness and spring construction.
Seepage or filtration spring. The term seep refers to springs with small flow rates in which the source water has filtered through permeable earth. Fracture springs, discharge from faults, joints, or fissures in the earth, in which springs have followed a natural course of voids or weaknesses in the bedrock.
