FAQ

What is the difference between the ‘FRB 180X5’ on the label and the ‘SR180x5’ engraved on the ring?

‘FRB 180X5’ is AKN’s specific manufacturer part number. ‘SR’ is a common abbreviation for ‘Sprengring’ or ‘Sicherungsring’ (German for retaining ring), and ‘180×5’ denotes the nominal dimensions (180mm diameter, 5mm width). The engraving indicates the generic type, while the label provides the exact order code.

Is this retaining ring for an internal bore or an external shaft?

This is an external retaining ring, designed to be fitted into a groove on a 180mm diameter shaft to secure components. Internal rings (for bores) typically have a different geometry and designation.

What is the material of this retaining ring and is it suitable for corrosive environments?

This ring is typically made from high-carbon spring steel. While it offers excellent strength and elasticity, standard spring steel is not inherently corrosion-resistant. For applications in wet or corrosive environments, a stainless steel version or a ring with a protective coating would be recommended. Please verify the material against your application’s requirements.
