The AirTAC AirTAC SDA16X75 Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 75mm 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 SDA16X75 is a double-acting single-rod compact cylinder engineered for tight axial footprints, delivering a 100.5 N push and 86.4 N pull at 0.5 MPa. Its riveted assembly securely joins the barrel, rear cover, piston, and rod to minimize overall length. This specific 75 mm stroke exceeds the 60 mm maximum standard for the 16 mm bore, making it a non-standard, made-to-order configuration.
The bore features a hard-anodized inner wall paired with a two-way piston seal for reliable service. End-stop deceleration is handled strictly by a fixed NBR bumper rather than an adjustable air cushion. Without a piston magnet on this SKU, position sensing is unavailable; the -S variant is required to utilize the body grooves for reed or electronic switches.

Provides the 100.5 N push at 0.5 MPa required to eject cut circuit boards from a routing fixture, utilizing the short riveted body to fit within dense electronics assembly machinery.
Drives a 75 mm stroke to fold lightweight cardboard flaps on a packaging line, where the fixed NBR bumper safely absorbs the end-of-travel impact without needing external adjustment.
Moves analytical trays between testing stations with a safe working load of 60 N, taking advantage of the 6 mm rod and compact footprint to minimize instrument depth.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA12 yields 56.5 N of push at 0.5 MPa, while stepping up to the SDA20 provides 157.1 N. For the current 16 mm bore, a safe working load is approximately 60 N (about 60% of the 100.5 N figure), translating to a vertical lift capacity of roughly 5.1 kg with a 2:1 safety margin. To order, confirm the 16 mm bore, 75 mm non-standard stroke, M5x0.8 port, female rod thread, and the absence of a magnet.
Remember that a standard SDA body cannot hold a load if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only slows the rod near stroke end and does not function as a locking brake. If your application demands position holding without live pressure, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This 16 mm bore double-acting cylinder generates a 100.5 N push and 86.4 N pull at 0.5 MPa, and a 140.7 N push at 0.7 MPa. The theoretical maximum push force is 21 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa at speeds of 30-500 mm/s.
The 16 mm bore has a maximum standard stroke of 60 mm, so the 75 mm length is a made-to-order item. Additionally, this SKU lacks the -S magnet option, meaning it cannot support reed or electronic switches, and relies on a fixed NBR bumper instead of an adjustable cushion.
