A new interlaced Spirawave spring is ideal for applications where extremely high forces and long deflections are required.
A new interlaced Spirawave spring is ideal for applications where extremely high forces and long deflections are required.
The unique spring comprises two or three large Smalley crest-to-crest Spirawave springs, wound together to form a single heavy-duty spring.
The interlaced spring delivers substantially higher forces but maintains excellent deflection characteristics to cater for the demanding engineering applications.
The interlaced spring is an ideal replacement for situations where disc-spring stacks or pocketed coil springs are used.
As a single component, it avoids the assembly difficulties associated with stacking and orientating disc springs and eliminates costly machining operations to house multiple coil springs.
The force generated relative to its diameter also means that the interlaced spring can save radial space, giving design engineers the option to reduce housing where space is an issue.
Several of TFC's major clients, particularly in the offshore oil industry, now specify the interlaced spring.
The option to manufacture parts from alloys including Elgiloy and Inconel X-750 means that it satisfies NACE approvals.
"The dimensions and output of the interlaced spring are unique", said Brian Goode, Technical Director at TFC.
"Not only does it satisfy applications that demand consistently high-forces and long-deflections, but it can also save on cost and space.
These attributes really do make it a force to be reckoned with".
