The AirTAC AirTAC SDA16X30H Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 30mm 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 SDA16X30H is a double-acting single-rod compact cylinder engineered for tight spaces, delivering a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa. Its short riveted body drastically reduces axial mounting depth compared to round-body alternatives, making it ideal for dense machinery layouts. This specific H-series configuration utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The unit features a 6 mm piston rod and an M5x0.8 port. Instead of an adjustable air cushion, it relies on a fixed NBR bumper at each end to decelerate the stroke. Without a piston magnet (-S option omitted here), it cannot host magnetic switches; the standard body grooves remain ready for sensor integration on upgraded variants.

Uses the 30 mm stroke to push singulated circuit boards off a routing fixture, where the FKM seals withstand residual heat from the cutting process.
Deploys the 100.5 N push force at 0.5 MPa to fold cardboard inserts into blister packaging trays within a confined axial footprint.
Drives a micro-dispense valve for chemical reagents, benefiting from the 6 mm rod and compact riveted body to minimize machine envelope size.
When sizing this 16 mm bore, stepping down to the SDA12 yields 56.5 N of push force at 0.5 MPa, while stepping up to the SDA20 provides 157.1 N. For this 100.5 N model, a safe working load is approximately 60 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 5.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 16 mm bore, 30 mm stroke, M5x0.8 port, female M3x0.5 rod thread, FKM seals, and no sensor magnet. Note that a plain compact cylinder drifts if air pressure is lost; the fixed bumper only decelerates near the stroke end and acts as neither a lock nor a brake. To hold a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa. At 0.7 MPa, the push increases to 140.7 N and pull to 121 N. The theoretical maximum push is 21 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a proof pressure of 1.5 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and is not a locking brake. To maintain position without live pressure, you must install an external rod lock or a pilot-operated check valve.
