Mono and dual flow rotary joints that carry water, steam, oil, air and coolant into rotating machinery, from paper-mill dryers to high-speed machine tool spindles.
Featured
Standard rotary unions for water, oil, steam and air transfer. Mono and duoflow balanced designs with interchangeable components, not affected by direction of shaft rotation. Widely installed in textile, printing, packaging, steel and rubber industries.
Multiport rotary unions: SHP 100/200/300 series for simultaneous transfer of multiple media circuits through a single joint. Torque transmission through drive lugs with all components held together for easier installation and removal. Designed for clear liquids, oil and air.
Machine tool rotary unions: SMT 100 to SMT 600 series for spindle cooling and fluid transfer in CNC machines, manufacturing and automation equipment. Balanced silicon carbide face seals with deep groove ball bearings. Compact, high-speed, low-maintenance design engineered for continuous operation.
Custom-designed rotary unions engineered to your exact requirements: special media, pressures, temperatures, flow passages and connections. Share your application details and our engineering team will design a rotary joint around it.
FAQ
A rotary union, also known as a rotary joint or swivel joint, is a precision-engineered device designed to transfer fluids (liquids or gases) from a stationary inlet to a rotating outlet. These components are critical in applications where continuous rotation is required while maintaining a leak-free connection for media such as water, oil, coolant, air or hydraulic fluid.
We manufacture standard rotary unions (1000–6000 series), multiport rotary unions (SHP 100/200/300), machine tool rotary unions (SMT 100–600) and custom-designed rotary unions built to customer requirements.
Our rotary unions are crafted using advanced technology and superior materials for unmatched performance. We offer both standard and custom-designed solutions tailored to your industry, built to withstand harsh operating conditions with minimal maintenance. Our team provides end-to-end support from product selection to installation and after-sales service.
Our rotary joints are used across paper, auto, rubber, sugar, plastic industries, spindle cooling applications, CNC machines, manufacturing, automation, aerospace, energy and food processing sectors worldwide.
A rotary union transfers fluid through a rotating joint, while a mechanical seal prevents leakage around a rotating shaft. Both handle rotating interfaces but solve different problems: rotary unions move media across the rotation; mechanical seals contain pressure at the shaft.
