External Spirolox® Rings

Spirolox® retaining rings are manufactured by rolling a flat wire ring and have many advantages over traditional fasteners or stamped retaining rings.

  • No gap – 360° support surface
  • Spirolox retaining rings have no protruding lugs that could interfere with fitting      components (uniform cross-section)
  • Eco-friendly production from stainless steel, as there is no waste in the coiling process
  • Smalley is the inventor of the spiral retaining ring
  • No processing fees for custom designs
  • Easy assembly and disassembly

Smalley WaveRings®

WaveRings are two-turn Spirolox® Retaining Rings with an axial waveform. These rings function similarly to a traditional retaining ring (providing a removable shoulder), but when installed, they offer a spring force that applies pressure against both the groove wall and the assembly components. This spring force compensates for tolerance stack-up or play.

Designed to fit into the groove. WaveRings exerts pressure in two directions: on the groove wall and on the mounting elements. Single, double or multiple rotations of the WaveRing are possible, as well as a choice of materials, including our standard 17-7 PH stainless steel and carbon steel.
