Component Specifications

Definition
A retaining ring is a fastener that holds components onto a shaft or in a housing/bore when installed in a machined groove. The groove provides a precise recess for the ring to seat, creating an axial shoulder that prevents movement. This system allows for easy assembly and disassembly without threading or additional fasteners, commonly used in rod glands and end caps to secure seals, bearings, or other internal parts.
Working Principle
The retaining ring is compressed or expanded to fit into the groove, then springs back to its original shape, locking into place. The groove's dimensions ensure the ring sits flush, creating a positive stop against axial movement. In rod glands/end caps, this prevents components from shifting under pressure or vibration.
Materials
Typically made from carbon steel (e.g., SAE 1070-1095), stainless steel (e.g., AISI 302/304), or beryllium copper for corrosion resistance. Material selection depends on load, environment, and temperature.

  • Groove Depth 0.3-2.0 mm
  • Groove Width 0.5-3.0 mm
  • Temperature Range -40°C to 120°C
  • Axial Load Capacity Up to 5000 N
  • Ring Diameter Range 5-100 mm
Standards
ISO 8750, DIN 471, DIN 472, ANSI B27.6

Frequently Asked Questions

What is the purpose of a retaining ring groove in a rod gland?

The groove provides a precise location for the retaining ring to seat, creating an axial stop that secures seals or bearings within the gland, preventing leakage or component displacement under pressure.

Can retaining rings be reused?

It is generally not recommended to reuse retaining rings, as they may lose spring tension or become deformed, compromising their holding ability and risking failure.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
