Spiral retaining ring WKT series

internal

Product overview

Description:
WKT series medium‑duty internal spiral retaining rings are coiled from flat wire to create a continuous, gapless ring providing a 360° retaining surface. Available in single‑turn and multi‑turn (including 2‑turn) configurations, they eliminate mounting ears for a reduced radial footprint. Coiling produces no scrap, enabling economical production in carbon steel, stainless steel, copper and other alloys.

Key features:

• 360° gapless retaining surface
• Manufactured from coiled flat wire — low waste
• Available single‑turn and multi‑turn (2‑turn) options
• No mounting ears — compact radial design
• Typical materials: carbon steel, stainless steel, copper, various alloys
• Common finishes: oil dip, passivation, blacking, plating (zinc/nickel/chrome/silver/gold), powder coat

Advantages:

• Space saving in radial direction due to absence of protruding lugs
• Cost‑effective manufacturing, especially in stainless steel
• Simple installation and removal for maintenance
• Wide applicability across mechanical equipment
• Durable service life when specified in appropriate material

Difference vs. conventional circlip:

• Appearance: circlips typically have process holes and protruding ears for pliers; spiral rings have no protrusions.
• Disassembly: circlips with holes are easier to remove frequently; spiral rings occupy less installation space but are less convenient for very frequent disassembly.
• Application: spiral rings are preferred where compact radial envelope and continuous 360° retention are required.
