English Translation of Title:
Lock Washer 25 – Waterjet Cutting Equipment Accessory (ID: 95838314)

Description, Purpose, Features, and Maintenance:

This component is a helical split‑type lock washer sized for 25‑mm diameter fasteners, used in waterjet cutting equipment to secure bolted connections on smaller subassemblies, sensor mounts, guide rail brackets, and low‑pressure water lines. It prevents fastener loosening induced by continuous machine vibration, rapid traverse motions, and pressure fluctuations.

Purpose:

• Maintains clamping force on lightly to moderately loaded bolted joints.

• Prevents rotational back‑off of nuts and bolts in areas subject to vibration and cyclic thermal changes.

• Compensates for minor thread settlement and surface embedding after initial torque application.

• Provides a mechanical locking solution in compact spaces where adhesives or wire locking are not feasible.

Features:

• Made from hardened spring steel with a corrosion‑resistant coating for long service life in humid cutting environments.

• Helical split geometry delivers consistent spring pressure around the entire fastener circumference.

• Sharp split edges bite into mating surfaces to create a positive anti‑rotation lock.

• Heat‑treated to maintain elastic memory within the recommended torque range.

• Lightweight and compact, suitable for 25‑mm bolt patterns common on accessory mounts and guarding panels.

Maintenance:

• Inspect for cracks, permanent flattening, or loss of spring gap before each reuse.

• Replace if the split ends are closed, the washer shows visible distortion, or surface rust has penetrated the coating.

• Clean with a dry cloth or compressed air to remove abrasive grit; avoid liquid cleaners that may leave residues.

• Install with the split ends facing the nut side for proper locking action.

• Replace all lock washers on a given joint as a set if any single unit shows signs of fatigue.
