Q Series Steam Rotary Joint – Self-Supported Design, OEM Ready

Description

Rotary Joint Steam Transfer for High-Temperature Application Product Overview:

The Q Type Rotary Joint Steam is a premium-grade rotary sealing solution designed for high-speed, high-temperature applications involving saturated or superheated steam. Ideal for use in cylinder dryers, calenders, textile finishing machines, and paper mills, this rotary joint ensures leak-free, low-torque rotation under extreme heat and pressure conditions.

The Q-type joint has a simple structure, stable sealing performance, no lubrication required, easy maintenance, and a spherical sealing structure. It can automatically adjust the center and automatically compensate. It can be applied to equipment with low speed and poor coaxiality. The products are widely used in various processing and manufacturing fields.

Key Features

Robust Q-Type Design

Compact and durable construction with high-quality materials like stainless steel (SS304/SS316) for corrosion resistance and longevity.Designed to withstand thermal expansion and harsh industrial conditions.

Automatic alignment/automatic compensation

The Q series rotary joint adopts a spherical sealing structure, which can automatically adjust the center and automatically compensate. The equipment with low speed and poor coaxiality can be accommodated by it. It has a simple structure, reliable sealing, and does not require lubrication. 

Maintaining sealing

The finely processed outer tube spherical surface, bottom cover, and sealing ring together form a dynamic seal friction pair. The sealing ring floats between the outer tube’s spherical surface and the bottom cover, but does not contact the housing. The oil-free bearing supports and guides the housing and the outer tube. When the seal ring wears, the housing will slowly move away from the shaft head with the help of the spring and the medium pressure to compensate for the normal wear of the seal ring. Therefore, the rotary joint and the pipeline connection must use a metal hose so that the rotary joint can move slowly away from the shaft head freely, and the rotary joint can maintain a seal. The seals are all made on CNC machine tools and grinders, the surface is like a mirror, and the sealing is reliable.

Simplified Structure for Enhanced Reliability

Our engineering team has actively refined and simplified the internal structure of the Q Series rotary joint. This ongoing optimization ensures not only reliable sealing and long-term operational stability but also significantly reduces the number of components, minimizing failure points and extending service life.

Easy Installation & Maintenance Without Shutdown

We’ve designed the Q Series rotary joint with maintenance efficiency in mind. Technicians can replace internal sealing components without removing the entire rotary joint and without shutting down the system. This tool-free serviceability reduces downtime, improves maintenance speed, and keeps your steam systems running at peak performance.
