Description

What is the air rotary joint?

 

The air rotary joint is a device designed to allow the flow of air between a stationary source and rotating components, such as shafts or cylinders, in a machine or system.

These seals are crucial in applications where compressed air or vacuum needs to be supplied to rotating machinery parts.

Optimising power transmission with rotary joints: A focus on tight sealing and efficiency

The air rotary joint plays a crucial role in the transmission of pressurised fluids, such as hydraulic oil, air or vacuum, from a fixed supply line to rotating components of a machine or cylinder.

These ingenious parts act as vital links, enabling the efficient transfer of power through rotating shafts, such as a machine shaft, while maintaining a tight seal.

Watertight sealing for optimum performance

One of the fundamental aspects of a rotary air seal is its ability to provide a tight seal, ensuring that there is no leakage between the pressurised supply line and the rotating machine or cylinder.

This sealing is essential to ensure leak-free performance and maintain system integrity. Advances in sealing technology have led to increasingly efficient designs that minimise the risk of failure and maximise durability.

Versatility in fluid transmission

Rotary joints are versatile and can handle a variety of fluids, including hydraulic oil, air or vacuum.

This versatility makes them suitable for a wide range of industrial applications where smooth power transmission is required.

From hydraulic systems controlling heavy machinery to applications involving compressed air or vacuum, rotary joints play an integral role in a variety of industrial environments.

Efficiency and reliability in secure environments

Designed for use in non-explosive environments and with non-combustible fluids, rotary joints offer reliable and safe performance.

The selection of robust materials and attention to manufacturing standards contribute to the durability and strength of these seals in demanding industrial environments.

Characteristics

Highlights of the rotary joints

 

  • Single-step design: Indicates that the rotating union is designed with a single duct for the passage of air. This simple design facilitates the efficient transfer of fluid through the joint.
  • Self-supporting rotary joint: This type of joint has the ability to support itself without relying excessively on external structures to maintain its position.
  • Radial body connection: The connection of the seal body to the system is made radially, which means that the connection is established in a plane perpendicular to the axis of rotation. This design can facilitate installation and maintenance.
  • Graphite/hardened steel compensated seals: Compensated seals are designed to accommodate variations in operating conditions, such as pressure and temperature. The combination of graphite and hardened steel suggests strength and durability in industrial environments.
  • Oil impregnated felt in seal cavity: The presence of oil-impregnated felt helps to maintain proper lubrication in the seal cavity, reducing friction and improving seal life.
  • Lubricant for relubrication (3-5 drops/month): The presence of a grease nipple indicates that the seal can be relubricated periodically to maintain smooth operation. The suggested amount of 3-5 drops per month provides an indication of maintenance needs.
  • Aluminium body: The seal body is made of aluminium, a material known for its light weight, corrosion resistance and durability.
  • Rotor in steel or stainless steel (depending on model): The choice of rotor material, either steel or stainless steel, may depend on the specific requirements of the application, such as corrosion resistance or environmental conditions.
  • Low torque: Indicates that the seal requires a low level of force to rotate, which can contribute to efficiency and wear reduction in the system.
