What is a Ring Spring?
A ring spring is of a number of alternately assembled inner and outer rings. Each ring has a lubricated conical contact surface that is made up of a high-quality spring steel.

The outer rings expand and inner rings contract when axial pressure isapplied to the ring spring. Each conical surface telescopes into the adjacent one.

The pairs of conical contact surfaces sum to provide a total spring travel that is directly proportional to the total number of elements. High efficiency results when the outer rings and inner rings are subjected to equally uniform compression stresses. The friction that occurs between the conical surfaces increases the force required to compress the spring and reduces the force given out on release.

Characteristics
There are three intrinsic characteristics of ring springs:

• Ring springs are used when weight or space is at a premium. Ring Springs have a very high capacity per pound of spring weight or per
  cubic inch of spring volume.
• Oscillations and harmonic vibrations are dampened by the natural
  friction of the spring.
• The travel and the spring constant are easily changed by adding and/or removingrings without affecting the ultimate compression or release force.
  
  

Lubrication
In order to reduce wear on the friction surfaces Ashby coats all of the conical surfaces with a heavy graphite grease. This coating also insures smooth action for the ring spring and reduces heat due to friction.
