English Translation of Title:
High-Pressure Swivel Joint – Spindle, 38 mm, for Water Jet Cutting Machine Parts, Model No. 49899602-High-Pressure-Swivel-Joints-Spindle-38.1144.3-1

Introduction, Application, Features, and Maintenance:

This component is a high‑pressure swivel joint spindle designed for water jet cutting systems. It is the rotating shaft or core element of a swivel joint assembly, featuring a 38 mm nominal size, that allows rotational movement between connected high‑pressure lines while maintaining a leak‑proof seal.

Application:
Used as the central rotating component in high‑pressure swivel joints within water jet cutting machines. It enables relative rotation between fixed and moving high‑pressure lines, typically in cutting head articulation, pump connections, or gantry system plumbing where motion must be accommodated without twisting rigid tubing.

Features:

• Rated for extreme pressures common in water jet cutting, up to 6,000 bar (87,000 psi).

• Precision‑machined spindle provides smooth rotation and accurate alignment.

• Manufactured from high‑strength, corrosion‑resistant material suitable for abrasive water jet media.

• Designed for 38 mm nominal size components.

• Precision‑ground sealing surfaces ensure leak‑free operation under dynamic conditions.

• Facilitates maintenance by allowing disassembly of the swivel joint.

Maintenance:

• Regularly inspect the spindle surface for signs of wear, scoring, pitting, or corrosion.

• Check for leakage around the swivel joint during machine operation.

• Verify smooth rotational movement; binding or roughness may indicate wear or contamination.

• Replace the spindle immediately if any surface damage, leakage, or loss of smooth rotation is detected.

• Use compatible seals and lubricants during reassembly.

• Clean and protect the spindle when not in use to prevent abrasive particle ingress.
