TFC is offering the Smalley Spirolox series of retaining rings. Unlike die-stamped circlips or retaining rings, Smalley Spirolox retaining rings and snap rings are coiled on edge to the exact diameter required.

TFC

Smalley Spirolox rings have a uniform cross section and no protruding lugs and are burr free. Smalley Spirolox rings offer a full 360° retaining surface and are directly interchangeable with standard imperial and metric standard circlip grooves.

Made from pre-tempered flat wire, Smalley Spirolox rings are made without the need of expensive tooling by edge coiling, which means, unlike conventional circlips, special designs can be easily accommodated and design changes can be made without any additional cost.

Key features and benefits

  • Spiral wound in multiple turns increases load capacity yet allows easy assembly by hand or as an automated process
  • Uniform radial section provides a pleasant appearance on the assembled product — beneficial when radial clearance is limited
  • Simplified assembly — wind into groove; no special pliers or tools needed to install or remove; removal notch provided for easy removal using a screwdriver
  • Available in a variety of materials including carbon spring steel, 302 and 316 stainless steels, plus exotic alloys such as Inconel, Elgiloy, A286, phosphor bronze and beryllium copper
  • Design flexibility — ring thickness can be changed to accommodate most applications by either varying material thickness and/or number of turns
  • Meets military and aerospace specifications
  • Can be coiled to exact specification in any diameter between 5mm and 2,300mm
