English Translation of Title:
Pneumatic Actuator Assembly – Normally Closed Retaining Ring for Water Jet Cutting Machine Parts, Model No. 10177772-Pneumatic-Actuator-Assembly-Normally-Closed-Retaining-Ring.982.3-1

Introduction, Application, Features, and Maintenance:

This component is a pneumatic actuator assembly featuring a normally closed retaining ring, designed for water jet cutting systems. It combines a pneumatic cylinder mechanism with an integrated retaining ring that secures components in a closed position when air pressure is not applied, ensuring fail‑safe locking or holding.

Application:
Used to lock, hold, or secure machine components such as cutting head assemblies, tool holders, covers, or valve mechanisms in water jet cutting machines. It is commonly employed in safety‑critical applications where components must remain clamped or locked upon loss of air supply.

Features:

• Normally closed retaining ring design provides fail‑safe locking (clamps when air is off).

• Pneumatic actuation allows remote or automated control of locking/unlocking.

• Manufactured from high‑strength, corrosion‑resistant materials for harsh water jet environments.

• Integrated assembly simplifies installation and reduces component count.

• Provides reliable holding force even under vibration and machine operation.

• Quick response for efficient machine cycling.

Maintenance:

• Regularly inspect the retaining ring, piston rod, and seals for signs of wear, corrosion, or damage.

• Check for air leaks at pneumatic connections during machine operation.

• Verify that the ring locks and unlocks smoothly; sticking may indicate contamination or seal wear.

• Replace seals or the assembly immediately if the ring fails to hold securely or if air leakage is observed.

• Use clean, dry, and lubricated air as recommended to extend actuator life.

• Follow the manufacturer’s recommended service intervals for seal replacement.

• Ensure mounting bolts and brackets are properly torqued.
