English Translation of Title:
Lock Washer 38 – Waterjet Cutting Equipment Accessory (ID: 95750394)

Description, Purpose, Features, and Maintenance:

This component is a helical split‑type lock washer sized for 38‑mm diameter fasteners, designed as a replacement part for general waterjet cutting equipment assemblies. It is installed beneath nuts or bolt heads on structural joints, pump mounts, and high‑pressure line brackets to prevent loosening caused by machine vibration, gantry acceleration, and hydraulic pressure fluctuations.

Purpose:

• Maintains bolt preload on frame connections, motor mounts, and piping clamp assemblies.

• Prevents rotational back‑off of fasteners in areas subject to continuous low‑frequency vibration and shock loads.

• Compensates for minor settlement and thermal movement in bolted joints during extended operation.

• Serves as a mechanical locking device in locations where thread‑locking liquids are impractical or prohibited.

Features:

• Manufactured from hardened spring steel with a corrosion‑inhibiting surface coating suitable for wet and abrasive environments.

• Helical split body provides uniform spring tension around the entire circumference of the fastener.

• Sharp split ends dig into the nut face and the underlying workpiece, creating a positive friction‑based locking action.

• Heat‑treated to retain elasticity through multiple torque cycles within the recommended range.

• Standard 38‑mm inside diameter ensures compatibility with common waterjet equipment bolt patterns.

Maintenance:

• Inspect for deformation, cracking, or loss of spring gap before every reassembly.

• Replace immediately if the split ends are fully closed, the washer is flattened, or any fracture is visible.

• Clean with a dry brush or compressed air to remove abrasive dust and debris; do not use acidic or caustic cleaners.

• Always orient the split ends toward the nut side (away from the stationary surface) for optimal gripping.

• Do not reuse if the washer has been overtightened or has experienced a single high‑load cycle beyond its elastic range.

• When installing multiple lock washers on the same joint, replace all units simultaneously to ensure uniform clamping distribution.
