Industrial automated equipment often needs to deliver multiple kinds of media from stationary pipelines to continuously rotating components. Instead of installing several single‑passage rotary unions, engineers choose multi‑passage rotary union (multi‑channel rotary joint) as an all‑in‑one fluid rotary transmission solution.

A multi‑passage rotary union integrates 2 or more independent isolated flow passages inside one compact housing. Each channel works separately, transmitting hydraulic oil, compressed air, vacuum, cooling water, coolant or nitrogen at the same time, no cross‑contamination between different media. It realizes 360° unlimited continuous rotation for rotating tables, robot joints, machine tool spindles and rotary fixtures.

In the industrial manufacturing sector, the multi-passage rotary joint is an unassuming yet critically important component. It acts as the "joint" of equipment, responsible for transferring various media—such as hydraulic oil, coolant, and compressed air—from a stationary end to a rotating end. Shandong Focus Machinery Co., Ltd. has served thousands of equipment manufacturers and end-users. Our commitment: More than just selling joints—a long-term partner in fluid transfer.
