Custom Designed Outer Ring of Shrink Disc

Shrink Disc Outer Ring: Robust Exterior with Superior Corrosion Protection

Our shrink disc outer rings serve as the sturdy external clamp, engineered to withstand high hoop stresses and environmental challenges. The Manufacturing Process emphasizes structural integrity and surface durability, culminating in a specialized anti-corrosion paint treatment that ensures long-term performance even in harsh operating conditions.

Anti-Corrosion Paint Treatment – Key Advantages

1.  

   Long-Term Rust Prevention:
   The coating isolates the base material from moisture, salt spray, and corrosive media, significantly extending service life in demanding environments.

2. Chemical Corrosion Resistance:
   Withstands erosion from oils and common industrial chemicals, maintaining surface integrity.

3. Cost Efficiency:
   Durable protection reduces maintenance frequency and long-term operating costs.

Key Differentiators Between Inner & Outer Rings

•  

  Inner Ring: Precision focus on bore accuracy, verified by CMM

• Outer Ring: Enhanced durability via protective paint coating

• Material Selection: Different grades selected based on functional requirements

• Process Sequencing: Tailored machining routes to match part geometries

Both components follow strict quality certifications and traceability protocols, ensuring perfect interoperability when assembled into complete shrink disc units.
