1. Rotary Indexing Tables in Automated Packaging Systems
In automated packaging equipment, rotating turntables require compressed air or vacuum to actuate fixtures, clamps, or suction cups. The Festo QSRL-3/8-8 fitting connects stationary pneumatic supply lines to these rotating fixtures. Its built-in rotary mechanism allows continuous 360-degree swiveling at speeds up to 400 rpm, ensuring that the 8 mm tubing does not tangle or twist during indexing cycles, while accommodating both compressed air up to 14 bar and vacuum down to -0.95 bar.
Problem SolvedPrevents pneumatic tubing from tangling, twisting, or shearing off when supplying continuous air or vacuum to rapidly indexing rotating turntable fixtures.

2. Pneumatic Expansion Shafts in Roll Converting Machines
Paper, film, and textile web handling machines use pneumatic expanding shafts to grip core rolls. These shafts continuously rotate during winding and unwinding processes and must maintain internal pressure to hold the rolls securely. The QSRL-3/8-8 allows 8 mm tubing to supply a constant 6 bar operating pressure to the R3/8 port of a shaft rotating at speeds up to 400 rpm. The NBR seal and high-alloy stainless steel clamp ensure leak-free operation despite continuous rotational friction.
Problem SolvedMaintains continuous, reliable air pressure to rotating expanding chucks without stopping the machine to repressurize, enabling continuous slip-free unwinding.

3. Continuous-Rotation Robotic End-of-Arm Tooling (EOAT)
Articulated robots and SCARA robots often feature a continuously rotating wrist axis to orient parts during pick-and-place operations. Routing rigid pneumatic lines to the end-effector causes torsional fatigue and tube kinking. Integrating the L-shaped QSRL-3/8-8 fitting at the wrist joint allows the end-effector to spin freely up to 400 rpm with a very low max radial torque of 0.015 Nm, preventing the 8 mm tubing from resisting the robot's movement or kinking during complex trajectory paths.
Problem SolvedEliminates torsional stress, kinking, and premature failure of pneumatic supply tubing at the rotating wrist joints of industrial robots.
