The AirTAC AirTAC SDA16X70SB Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 70mm 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 SDA16X70SB is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly minimizes axial mounting depth compared to conventional round-body units. Delivering 100.5 N of push force at 0.5 MPa, it features a hard-anodized 16 mm bore and a two-way piston seal for reliable pneumatic actuation.
This specific configuration includes a built-in piston magnet for position detection via AirTAC reed or electronic switches. The rod end utilizes a male M5x0.8 thread for direct load coupling. Because the 70 mm stroke exceeds the 60 mm standard maximum for this bore, it is manufactured as a made-to-order unit. End-of-stroke deceleration is handled by fixed NBR bumpers rather than adjustable cushions.

Actuates a routing tool guide on an electronics assembly line, where the 100.5 N push force cleanly separates printed circuit boards within a shallow machine enclosure.
Pushes lightweight parcels on a logistics conveyor belt, utilizing the male M5x0.8 rod end for secure bracket mounting and the sensor magnet to confirm divert positions.
Provides the precise 70 mm travel and clamping pressure required to seal pharmaceutical blister packs, requiring an external shock absorber to manage approach speeds.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA12 provides 56.5 N of push at 0.5 MPa, while moving up to the SDA20 yields 157.1 N. The SDA16X70SB itself offers a safe working load of roughly 60 N (about 60% of its 100.5 N capacity) and a vertical lift capability near 5.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 16 mm bore, 70 mm non-standard stroke, M5x0.8 port, male M5x0.8 rod thread, and the integrated magnet.
Remember that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered. The piston will drift, as the fixed NBR bumper only decelerates the stroke end and acts as neither a lock nor a brake. For suspended or gravity-loaded applications, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This 16 mm bore 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. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, it uses fixed NBR bumpers at each end to decelerate the piston near stroke completion. These are not field-adjustable air cushions. For high-energy or high-speed cycles, you should add an external shock absorber or reduce the approach speed. Additionally, the 70 mm stroke is a non-standard, made-to-order length for this 16 mm bore.
