Description;
The RJ-1230 Multiple Pass Rotary Joint is engineered to transfer multiple independent media streams through a rotating interface without cross-leakage between passages. Its multi-channel construction allows hydraulic oil, pneumatic air, coolant, water-glycol, or low-viscosity process fluids to pass through stationary piping into rotating shafts, indexing tables, reels, drums, and automated machinery.
Designed for industrial duty, the RJ-1230 is suitable for continuous or intermittent rotation where compact installation, stable sealing, and reliable media separation are required. The joint can be configured with precision-machined flow passages, wear-resistant sealing elements, and corrosion-resistant hardware for automation systems, machine tools, steel processing equipment, paper converting machinery, and rotary fixtures.
Technical Key Features;
- Suitable for continuous, indexing, or oscillating rotational motion.
- Optional stainless-steel construction for wet, corrosive, or washdown environments.
- Available with threaded, flanged, or custom port connections to suit machine layouts.
- Serviceable design supports planned maintenance and reduced equipment downtime.
- Compact rotary interface reduces hose twisting, pipe stress, and external routing complexity.
- Multi-passage design enables independent transfer of hydraulic, pneumatic, coolant, and utility circuits.
- Precision sealing arrangement minimizes internal bypass and prevents cross-contamination between passages.
