Pneumatics
Questions to write down before you size a cylinder
Load, port pressure, stroke and mount, with a worked vertical-lift example from a published cylinder guide.
Air on a packaging line
Notes on valves, tubing and motion
Rexroth Pneumatics records the inputs a cylinder needs, the way a purity class is written, and the questions that sit between a bad container and the ram that should push it off.
Start with the inputs
Compressed Air Dryer Selection: Refrigerated vs. Desiccant and ISO 8573-1 Dew Point Classes
Compressed air dryer selection guide: ISO 8573-1:2010 water classes 1–6, refrigerated +3 °C vs. twin-tower desiccant -40 °C to -70 °C dryers, CAGI ADF 100 derating, and coalescing filtration.
Compressed Air Leak Detection: Ultrasonic Survey Physics, FRL Unit Leak Points, and Orifice ROI
Compressed air leak detection engineering guide: 38–42 kHz ultrasonic probes vs. MEMS acoustic cameras, choked orifice SCFM and USD/yr ROI tables, and FRL unit leak points.
Pneumatics
Inputs to write down before a bore is chosen: load, pressure at the work port, stroke and mount. Open Pneumatics.
Double-Acting Pneumatic Cylinder Sizing: Force Equations, Air Consumption, and Rodless Alternatives
Double-acting pneumatic cylinder sizing guide: ISO 15552 and ISO 6432 extend vs. retract force formulas, dynamic load factors, ISO 8778 air consumption, PPV/PPS cushioning, and rodless cylinders.
Pneumatic Flow Control Valve Sizing: Meter-Out vs. Meter-In Speed Controllers and ISO 6358 Flow
Pneumatic flow control valve engineering guide: meter-out vs. meter-in cylinder speed controller physics, ISO 1219-1 symbols, ISO 6358 sonic conductance C sizing, and quick exhaust valves.

Air preparation questions for a packaging line
How ISO 8573-1:2010 writes particle, water and oil classes, and why a sample after the hose can fail a class that passed at the filter.
A blank plan for a compressed-air leak survey
Tag, record, repair and check again. Two flow cells are quoted from a 2004 public tip sheet. Estimate the orifice before you copy a flow.
Packaging lines
A task-by-task comparison of an air cylinder and a servo, and a checklist from the fault signal to the reject ram. Open Packaging lines.
Pneumatic vs. Electric Actuator TCO: Energy Efficiency, Servo Changeover, and Rodless Cylinders
Pneumatic vs electric actuator TCO: 8%–18% vs. 65%–82% energy efficiency, 5-year payback equations, servo vs pneumatic changeover OEE, and rodless pneumatic cylinder mechanics.
When a packaging motion is air, and when it is a servo
A task comparison of an air cylinder and an electric actuator, using two published articles.
Checklist from a bad container to the reject ram
Questions that tie a fault signal to the container the ram pushes off, using one published inspection station as the example.
