Different Kinds of Spring

Cantilever V-Spring

 

V-Spring is made by forming and stamping thin strips of metal sheets through progressive dies. V-Spring offers a very linear load curve, meaning that the more it’s deflected, the more force it applies.

 

It provides more of a point load in the jacket, focusing energy at the leading edge of the seal lips. This makes it desirable in reciprocating applications requiring the scraping of media. Multiple springs can also be stacked together for even greater loading.

 

 

Canted Coil Spring

Canted Coil is one of Eclipse’s specialties and we manufacture our own spring in-house. Canted Coil is typically used in applications where low friction and consistent loading are needed.

 

It possesses a very unique load curve where spring force changes very little despite varying deflection. This uniform and predictable loading makes it the spring of choice for most rotary applications.

 

 

Helical Ribbon Spring

A helical spring is made by winding a thin, flat strip of metal into a helix, creating a round tube. Helical has a very steep load curve and offers the highest force per linear inch.

 

It’s most often used in static face seal applications and in cryogenics where high loading is needed. It can be yielded after being compressed so it’s usually not recommended for dynamic applications.
