Custom Hourglass-Shaped Compression Springs

Hourglass Shape Allows the Spring to Center Over a Larger Hole

Hourglass-shaped compression springs, also referred to as concave shaped springs, have a smaller diameter in the middle of the spring and a larger diameter at each end. It is not required that each end diameter be the same, or for the narrowest part of the diameter to be in the exact middle of the hourglass spring’s length. Customers often select this compression spring shape as the larger end diameter allows the part to be centered over a hole, while often allowing a lower solid height than a constant diameter spring.

CSPI Spring offers expert design assistance and can review a variety of compression spring shapes and specifications. Our team offers years of hourglass compression spring manufacturing experience, and can discuss design and production considerations that can ensure performance and cost-effective manufacturing.
