Lock Washer for waterjet pump – 50 mm, Model No. 95413696-Lock-Washer-50-Waterjet-Pump.839.3-1

Introduction, Application, Features, and Maintenance:

This component is a lock washer designed for waterjet pump systems. It is a split‑ring or high‑collar type fastener with a central hole, sized for 50 mm bolts or screws, used to prevent fasteners from loosening due to vibration or dynamic loading under high‑pressure operation .

Application:
Used under bolt heads or nuts in waterjet cutting machines to provide a locking action that resists loosening. Typical installations include securing critical components in hydraulic power packages, intensifier pump assemblies, and structural frame connections where vibration is present .

Features:

• Sized for 50 mm bolts or screws (50 mm nominal diameter).

• Split‑ring or high‑collar design provides spring‑like tension to resist loosening under extreme hydraulic pressure and vibration .

• Manufactured from high‑strength, corrosion‑resistant material suitable for harsh waterjet environments .

• Helps maintain clamping force under dynamic conditions.

• Standard dimensions ensure compatibility with 50 mm fasteners.

Maintenance:

• Regularly inspect the lock washer for signs of corrosion, deformation, or loss of spring tension.

• Check for proper seating under bolt heads or nuts.

• Replace immediately if the washer is deformed, cracked, corroded, or no longer provides locking action.

• Ensure the washer is the correct size for the bolt being used.

• Use a new lock washer when reassembling components to ensure proper locking function .
