The AirTAC AirTAC SDA16X25SBH Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 25mm 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 SDA16X25SBH is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its riveted body assembly significantly reduces axial mounting depth compared to round-body units, delivering a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa. This specific configuration includes a male M5x0.8 piston rod end, a built-in piston magnet for position sensing, and fluororubber (FKM) seals for enhanced thermal and oil resistance.
Instead of an adjustable air cushion, the bore relies on a fixed NBR bumper at each end to decelerate the stroke. For high kinetic energy applications, slowing the approach speed or adding an external shock absorber is recommended. The integrated magnet interfaces directly with AirTAC reed or electronic switches mounted in the body grooves, and the 6 mm piston rod is designed for straightforward load coupling while strictly avoiding side loading.

Provides a compact 25 mm stroke to push singulated circuit boards out of a routing fixture, utilizing the FKM seals to withstand localized flux residue and heat.
Applies 100.5 N of clamping force at 0.5 MPa to hold thin plastic films against a heated die, fitting neatly within the narrow axial envelope of packaging machinery.
Drives a micro-valve for precise chemical dosing, where the male M5x0.8 rod end securely mounts the dispense head and the magnetic switch tracks fluid delivery.
When sizing this 16 mm bore actuator, evaluate your force margins carefully. Stepping down to the SDA12 provides 56.5 N of push force at 0.5 MPa, whereas stepping up to the SDA20 yields 157.1 N at the same pressure. Based on the 100.5 N push rating, the safe working load is approximately 60 N, which translates to a vertical lift capacity of about 5.1 kg when applying a 2:1 safety margin.
This SDA16X25SBH configuration specifies a 16 mm bore, a 25 mm stroke, and an M5x0.8 port. It includes the S option for the piston magnet, the B option for the male M5x0.8 rod thread, and the H option for FKM seals. Note that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 16 mm bore 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 force is 140.7 N and the pull force is 121 N. The theoretical maximum push force is 21 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30 to 500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a locking brake. For high-speed cycling, you should slow the approach or add an external shock absorber. The included S option provides a piston magnet for use with AirTAC reed or electronic switches in the body grooves.
