The AirTAC SDA16X70B 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 SDA16X70B is a double-acting single-rod compact cylinder engineered to deliver 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. Featuring a 16 mm bore and a 70 mm stroke, this unit uses a short riveted body that significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for tight machine footprints. The bore is hard-anodized and utilizes a two-way piston seal for reliable operation.
This specific SKU includes a male M5x0.8 threaded piston rod (denoted by the B option) instead of the default female M3x0.5 thread, providing a robust connection point for your load. Because the 70 mm stroke exceeds the 60 mm maximum standard stroke for this 16 mm bore, this is a non-standard, made-to-order configuration. It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. Note that this version lacks a piston magnet and therefore cannot support magnetic sensing.

Drives a high-speed routing bit head on an electronics assembly line to singulate printed circuit boards, utilizing the 70 mm stroke and 100.5 N push force to traverse the cutting axis.
Actuates a narrow deflector flap on a packaging conveyor to push lightweight plastic enclosures into a secondary sorting lane without taking up valuable frame width.
Moves a micro-fluidic dispensing valve over a multi-well plate in an automated laboratory instrument, benefiting from the short body length to fit inside a compact testing chamber.
When sizing this actuator, consider stepping down to the SDA12, which provides 56.5 N of push force at 0.5 MPa, or stepping up to the SDA20, which yields 157.1 N at the same pressure. Keep in mind that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates it near the stroke end. For applications requiring a held load, an external rod lock or pilot-operated check valve is required. To order, confirm the 16 mm bore, 70 mm non-standard stroke, M5x0.8 port, male M5x0.8 rod thread, and no magnet.
Quick checklist
This 16 mm bore double-acting cylinder provides 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 force is 140.7 N and the pull force is 121 N. The theoretical maximum push force is 21 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and the operating speed spans 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot be used with AirTAC reed or electronic switches. To add sensing capabilities, you would need the SDA16X70BS variant, which includes the built-in magnet for compatibility with magnetic switches mounted in the body grooves.
