Swivel Rotary Joint for Construction Machinery
Heavy-duty swivel joint rated 40 MPa for excavator and construction equipment slew circuits
Overview
Construction machinery — excavators, cranes, drilling rigs and similar equipment — relies on a heavy-duty swivel joint to route hydraulic oil across the rotating superstructure while the machine slews through its working arc. The Ruitus construction machinery rotary joint is rated at 40 MPa working pressure, 60 r/min rotational speed and 200°C temperature, a specification envelope that covers mainstream excavator slew and swing circuits. The joint is built for shock loads and contaminated hydraulic oil typical of site duty, with sealing and bearing arrangements selected for long service intervals. Detailed technical parameters and dimensions are confirmed per equipment model — contact Ruitus with your machine specification.
