Retaining Ring Detailed Information
 Smalley spiral retaining rings offer many advantages over stamped retaining rings:
- No Gap - 360° retaining ring surface provides dimensional stability
- No protruding ears to interfere with mating components
- Economically produced in stainless steel because the coiling process produces no scrap
- No Tooling Charge™ on specially designed snap rings
- Over 5,000 standard retaining rings
- Easy installation and removal
WH & WS Medium Duty Series Retaining Rings
The WH & WS Series Spiral Retaining Ring is Smalley's most popular retaining ring series. Smalley engineers have developed the greatest number of standard retaining ring sizes in this series, allowing customers to easily select and order parts for their applications. WH & WS snap rings easily handle thrust loads imposed by light or medium series bearings.
