Oil rotary union

for compressed air4-passageprecision

Short Description
Solid shaft rotary union with 80 mm outer diameter and 4 independent flow channels. Net weight 2.4 kg. Precision rotary joint designed for continuous transmission of hydraulic, pneumatic and general industrial fluids between stationary piping and rotating assemblies.

Product Overview
This solid-shaft, multi-passage rotary union provides reliable media transfer for rotating machinery and automation modules. The 80 mm solid outer diameter increases structural rigidity and reduces deformation under long-cycle rotation. Four isolated passages allow simultaneous transmission of different media without cross-contamination. The compact integrated construction simplifies installation in space-constrained equipment.

Core Product Advantages

• 80 mm solid outer diameter shaft: enhanced structural strength and resistance to torsion and impact
