Festo QSR-M5-4 Series Pneumatic Rotary Union, 4mm Tube Connection Size, 14 Bar Maximum Operating Pressure - QSR-M5-4

This pneumatic rotary union provides a rotating pneumatic connection to transfer compressed air between a stationary supply and a rotating part. Designed for medium-pressure pneumatic systems, it accommodates a push-in 4mm tube and a male M5 threaded inlet, enabling continuous rotation while maintaining an air feed. The device is suitable for installations operating within a controlled temperature range and where adherence to specified contamination classes is required.

Features and Benefits:

• Maximum operating pressure 14 bar enables stable compressed-air performance
• Maximum rotational speed 500 rpm supports high-speed rotary applications
• Push-in 4mm connection allows quick tube installation and removal
• Male M5 thread ensures standard metric connection compatibility
• Constructed from polybutylene terephthalate for chemical and wear resistance

Applications

• Suitable for rotary joints in packaging machines
• Ideal for pneumatic swivels on automated assembly heads
• Used with rotating air tools requiring compact feed‑throughs
• Can be used for indexing tables needing continuous air supply
• Appropriate for pneumatic actuation in rotating inspection systems

What environmental temperatures can it operate within?

It functions between 0°C and 60°C, suitable for typical factory ambient conditions.

Is the design suited to prolonged high-speed rotation?

With a rated limit of 500 rpm, it is intended for sustained use at moderate rotational velocities rather than extreme‑speed applications.

What connection standards are required for installation?

Installations need a metric-compatible female thread for the M5 male connection and tubing sized for a 4mm push-in port.
