The AirTAC AirTAC SDA16X5H Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 5mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA16X5H is a double-acting single-rod compact cylinder engineered for exceptionally tight axial spaces. Its riveted body assembly minimizes mounting depth while delivering 100.5 N of push force at 0.5 MPa. This specific SKU features an FKM fluororubber seal for enhanced thermal and oil resistance, operating reliably within the -20 to +70 C range.
Equipped with a 6 mm piston rod and an M5x0.8 port, this 5 mm stroke unit relies on a fixed NBR bumper at each end to decelerate the stroke. It lacks a piston magnet, meaning it cannot support position sensing without switching to the -S variant. The compact footprint makes it ideal where traditional cylinders cannot fit.

Provides the precise 5 mm extension needed to lower test probes onto populated circuit boards without damaging delicate traces.
Executes rapid short-stroke tucking movements on automated packaging lines to close small corrugated box flaps securely.
Drives micro-liter fluid dispensing valves in analytical laboratory equipment where a compact footprint and FKM chemical resistance are critical.
When sizing this 16 mm bore unit, consider stepping down to the SDA12 which provides 56.5 N push at 0.5 MPa for lighter duties, or moving up to the SDA20 which yields 157.1 N at 0.5 MPa for heavier loads. The computed safe working load for this model is approximately 60 N, allowing a vertical lift of about 5.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 16 mm bore, 5 mm stroke, M5x0.8 port, female M3x0.5 rod thread, FKM seals, and no magnet. Remember that a standard cylinder drifts when air pressure is lost; if your process requires strict position holding on air loss, you must integrate an external rod lock or pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 100.5 N push and 86.4 N pull at 0.5 MPa, increasing to 140.7 N push and 121 N pull at 0.7 MPa. The theoretical maximum push force is 21 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
You cannot adjust the end-stop cushioning; the cylinder uses a fixed NBR bumper to decelerate the stroke, which is not an adjustable air cushion. Additionally, this specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches unless you specify the -S magnet option on your order.
