Industrial Applications

1. Cleanroom Packaging Line Tray Indexing

Utilizing the cylinder to precisely index and position medical product trays in an automated filling line. The ISO Class 6 cleanroom rating ensures strict environmental compliance.

Problem Solved

Prevents particulate contamination during the handling of sterile products while delivering sufficient theoretical advance force (482.5 N at 0.6 MPa) to smoothly push loaded trays without stalling across its 40 mm stroke.

2. Defective Part Ejection on Fragile Parts Conveyor

Operating as an automated reject kicker on a conveyor belt sorting delicate components. The adjustable pneumatic cushioning (PPV) decelerates the 32mm piston smoothly to avoid high impact energy at the end positions.

Problem Solved

Eliminates impact-induced damage to delicate components during automated sorting by utilizing 14 mm length adjustable end-of-stroke cushioning and precise proximity switch position detection for exact ejection timing.

3. Component Clamping for Automated Assembly Jigs

Employed in a custom assembly fixture to clamp plastic housing halves together prior to ultrasonic welding. The M10x1.25 piston rod thread allows direct attachment of custom Delrin tooling blocks.

Problem Solved

Maintains a consistent holding force to prevent part slippage or misalignment during high-frequency vibrations, utilizing the moderate corrosion stress (CRC 2) rating to withstand industrial lubricants and repeated high-speed cycles.
