The AirTAC AirTAC SDA100X70S 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 SDA100X70S is a double-acting single-rod compact cylinder engineered for heavy-duty pneumatics within a minimal axial footprint. Its riveted assembly integrates the barrel, rear cover, piston, and rod, drastically reducing mounting depth compared to conventional round-body units. Delivering a substantial 3927 N push at 0.5 MPa, it incorporates a 32mm piston rod and a PT3/8 port to handle high flow requirements.
This 100mm bore variant features a built-in piston magnet (-S) compatible with AirTAC reed or electronic switches, fitting neatly into the body's sensor grooves for precise position detection. The internal hard-anodized bore and two-way piston seal ensure longevity, while fixed NBR bumpers absorb end-stop impact. With a safe working load around 2356 N (roughly 60% of the 0.5 MPa push force), it is well-suited for robust industrial handling.

Provides the high push force needed to eject heavy metal panels from a stamping die, utilizing the 70mm stroke to clear the press bed quickly.
Acts as a primary motion actuator in press brakes, delivering 5497.8 N at 0.7 MPa to form thick steel plates with consistent clamping pressure.
Handles vertical lifting of dense palletized goods in packaging lines, where the compact riveted body saves critical vertical machine space.
When sizing this model, evaluate stepping down to the SDA80, which provides 2513.3 N push at 0.5 MPa, or confirm if the SDA100X70S is required for your maximum 801 kgf output at 1.0 MPa. For vertical lifts, calculate approximately 200.2 kg with a 2:1 safety margin. Remember that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near the stroke end and does not function as a locking brake. To hold a load securely without live pressure, integrate an external rod lock or pilot-operated check valve. To order, confirm the 100mm bore, 70mm stroke, PT3/8 port, female M18x1.5 rod thread, and the required -S magnet.
Quick checklist
This 100mm bore double-acting cylinder provides a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push increases to 5497.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa.
No, the SDA100X70S uses fixed NBR bumpers at each end to decelerate the piston; it does not have an adjustable air cushion. Additionally, it cannot hold a load if air is lost, as the bumper is not a brake. For load holding, you must use an external rod lock or pilot-operated check valve.
