Radially Assembled Retaining Rings

Radially installed retaining rings combine simplicity, choice of configurations, and functional design. Since radial retaining rings do not extend as far around the circumference of the groove as their axial counterparts, they accommodate less force. Therefore when thrust loading capabilities are a secondary consideration for an application, radial retaining rings may be the right choice. Radial retaining rings are available in a variety of configurations to ensure the part suits application requirements. Sizes available from:
  • Standard: .040” to 3.375” (1 mm to 86 mm)
  • Custom: Contact manufacturer for use in larger applications

Tapered Section Radially Installed Rings


Radially installed retaining rings are designed for applications where installation needs to be radial, when axial installation is impossible due to interference from other components. By machining a groove onto the shaft and installing the ring, the shoulder will ensure components are held securely in place. Since these radial retaining rings don’t come with lug holes, special tools known as applicators and dispensers, as well as tailored packaging options can make quick work of installation.
