The AirTAC AirTAC SDA100X70B Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 70mm 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 SDA100X70B is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Delivering a substantial 3927 N push at 0.5 MPa, it utilizes a short riveted body that significantly reduces mounting depth compared to conventional round-body actuators. This specific configuration features a robust Ø32 mm piston rod with a male M26x1.5 thread end, paired with PT3/8 air ports to handle high flow requirements.
Instead of an adjustable air cushion, the internal stroke ends are protected by a fixed NBR bumper that decelerates the piston near travel limits. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches. Operating efficiently between 30-500 mm/s, the hard-anodized bore ensures long service life even under demanding cyclic loads.

Provides the heavy push force needed to eject thick metal blanks from progressive stamping dies, utilizing the male M26x1.5 rod for secure tooling attachment.
Lifts heavy layered product loads within end-of-line packaging machinery where the short riveted body minimizes vertical space requirements.
Applies high clamping pressure to hold large resin molds securely during cooling cycles, relying on the 3927 N output at 0.5 MPa.
Selecting this 100 mm bore actuator involves sizing both ways: stepping down to the SDA80 yields 2513.3 N push at 0.5 MPa, whereas this SDA100X70B provides 3927 N, offering a safe working load of roughly 2356 N (about 60% of the 0.5 MPa figure) or a vertical lift capacity of 200.2 kg with a 2:1 safety margin. When ordering, confirm the 100 mm bore, 70 mm stroke, PT3/8 port, male M26x1.5 rod thread (B option), and the absence of a sensor magnet. If your application requires position holding on air loss, note that the piston will drift and the fixed bumper only decelerates near stroke end—it is not a lock or brake, so an external rod lock or pilot-operated check valve is required.
Quick checklist
This double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push at 0.7 MPa. The theoretical maximum push force is 801 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No adjustable air cushion is available; it uses a fixed NBR bumper at each end to decelerate the stroke, so for high energy you should add an external shock absorber. Additionally, this specific SKU lacks the -S magnet, meaning it cannot host reed or electronic switches without changing to the -S variant.
