Component Specifications

Definition
The Holder Ring is a circular mechanical component designed to apply consistent radial clamping force within holder/flange assemblies. It functions as an interface element that maintains alignment, prevents axial movement, and distributes loads evenly across connected parts. Typically installed between mating surfaces, it ensures secure attachment while accommodating thermal expansion and vibration damping in industrial machinery.
Working Principle
Operates on the principle of radial compression, where tightening mechanisms (such as bolts or hydraulic pressure) cause the ring to contract uniformly, creating a 360-degree clamping force that secures internal components against the holder or flange. This eliminates point loading and maintains concentricity.
Materials
Commonly manufactured from alloy steels (e.g., AISI 4140, 4340), stainless steels (304, 316), or tool steels, with surface treatments like nitriding, chrome plating, or black oxide for corrosion resistance and wear protection.
Technical Parameters
  • Width 10-100 mm
  • Hardness HRC 40-60
  • Tolerance ±0.05 mm
  • Outer Diameter 50-500 mm
  • Pressure Rating Up to 300 MPa
Standards
ISO 286-2, DIN 7154
