Marcel Expanders are available as a custom from Smalley. Smalley engineers are available to assist with spring design. For more information, email Smalley engineering now.
Expanders can also be formed in a circle. The expander will provide radial force or outward pressure. These can be used behind seals to energize them when no pressure is available.
A Marcel expander can also be used for tolérance take up or to self center an assembly.
