Reliable sealing under the demanding conditions of paper & rubber cylinders

The 701 Series Rotary Joint features a heavy-duty construction designed for high-pressure applications. It is widely used in paper and rubber industry heating and drying cylinders, delivering reliable sealing performance, efficient fluid transfer, and extended service life under demanding operating conditions.

Key features

Robust construction with flexibility to suit the application

The 701 Series combines flow and syphon configuration options with a heavy-duty construction and sealing arrangement built for high-pressure, continuous-duty cylinder service.

Single & dual flow condition

Available for different steam transfer applications.

Stationary & rotary syphon condition

Suitable for both stationary and rotary syphon applications.

Spheroidal graphite cast steel housing & SS working parts

Robust construction provides reliable performance and durability.

Carbon graphite concave type sealing

Concave type carbon graphite sealing provides reliable sealing performance during operation.

One wide spaced guide

Wide spaced guide provides improved stability and support during rotation.

Various sealing grades available

Different sealing grades are available according to the application.

An adjustable syphon clearance option is also available, allowing flexibility to suit different application requirements.

Concave sealing & wide spaced guide

Stability and sealing performance, engineered together

The concave carbon graphite seal and the wide spaced guide work together to keep the joint stable and sealed under high-pressure, continuous cylinder rotation.

  • Concave seal geometry for reliable contact

    Concave type carbon graphite sealing provides reliable sealing performance during operation, maintaining consistent contact across the seal face under high-pressure steam conditions.

  • Wide spaced guide improves rotational stability

    One wide spaced guide provides improved stability and support during rotation — reducing the vibration and misalignment that would otherwise accelerate seal wear.

  • Adjustable syphon clearance

    An adjustable syphon clearance option allows flexibility to suit different application requirements, without needing a different joint configuration for each installation.
