The AirTAC AirTAC SDA100X45SB Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 45mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA100X45SB is a double-acting, single-rod compact cylinder engineered to deliver a substantial 3927 N of push force at 0.5 MPa. By utilizing a short riveted body that permanently joins the barrel, rear cover, piston, and rod, this unit drastically reduces axial mounting depth compared to conventional round-body actuators. It features a robust 32 mm piston rod and operates at speeds between 30 and 500 mm/s.
This specific configuration includes an internal piston magnet (-S) for position detection using an AirTAC reed or electronic switch, along with a male M26x1.5 threaded rod end (-B) for secure mechanical coupling. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or utilize external shock absorbers under high energy loads.

Drives heavy stamping dies and holding fixtures where the 5497.8 N extend force at 0.7 MPa is required to form vehicle body panels securely.
Actuates heavy-duty mechanical gripper jaws on end-of-arm tooling to lift full 200 kg pallet loads of consumer goods, utilizing the male M26x1.5 rod for a rigid load coupling.
Applies concentrated opposing pressure to flatten thick steel plates in a metal fabrication line, relying on the fixed NBR bumper to absorb the high impact energy at stroke end.
Selecting this 100 mm bore actuator involves evaluating your load against its 3927 N push capacity at 0.5 MPa. If your application requires less force, stepping down to the SDA80 provides 2513.3 N of push, which may better suit medium-duty tasks while saving space. Since 100 mm is the largest available bore in this series, there is no larger SDA option for scaling up. A computed insight reveals a safe working load of roughly 2356 N (about 60% of the 0.5 MPa figure), allowing for a vertical lift of approximately 200.2 kg with a 2:1 safety margin.
When ordering, confirm the essential parameters: 100 mm bore, 45 mm stroke, PT3/8 port thread, the built-in magnet (S), and the male M26x1.5 piston rod thread (B). Keep in mind that a plain compact cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift. For applications requiring load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 100 mm bore double-acting cylinder uses a PT3/8 air port. It generates 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, and a theoretical maximum push of 801 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the directional valve is centered. The fixed NBR bumper only decelerates the rod near the stroke end and does not act as a locking brake. To maintain a vertical load safely, you must add an external rod lock or a pilot-operated check valve.
