The AirTAC AirTAC SDA80X100S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 100mm 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 SDA80X100S is a double-acting, single-rod compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. Utilizing a short riveted body design, it significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for machinery where space savings are critical. The integrated -S option provides a built-in piston magnet for direct compatibility with AirTAC reed or electronic switches along the body grooves.
This 80 mm bore model features a 25 mm piston rod and a PT3/8 port. It relies on a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion. Operating efficiently between 30-500 mm/s, it handles high-energy cycles well when paired with external shock absorbers.

Drives heavy ejector pins in plastic injection molding machines where the short riveted body minimizes axial footprint behind the mold platen.
Secures heavy machining pallets on vertical CNC centers, utilizing the 2513.3 N push force to lock workholding fixtures firmly in place.
Elevates thick steel coils or plates in automated press feed lines, benefiting from the 128.1 kg vertical lift capacity with a 2:1 margin.
When sizing this unit, consider stepping down to the SDA63 which provides 1558.6 N push at 0.5 MPa, or moving up to the SDA100 which yields 3927 N push at 0.5 MPa. The SDA80X100S offers a computed safe working load of roughly 1508 N (about 60% of its 0.5 MPa capacity) and can vertically lift approximately 128.1 kg with a 2:1 safety margin.
To finalize your order, confirm the 80 mm bore, 100 mm stroke, PT3/8 port, female M14x1.5 rod thread, and the required -S magnet. Note that a plain compact cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near stroke end and does not function as a lock. For suspended loads, an external rod lock or pilot-operated check valve is required.
Quick checklist
The SDA80X100S generates a push force of 2513.3 N and a pull force of 2267.8 N at 0.5 MPa. At 0.7 MPa, the push force is 3518.6 N. The theoretical maximum push force is 513 kgf at 1.0 MPa.
No, this cylinder uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits. It is not an adjustable air cushion. For high-speed or high-energy cycles, you should slow the approach speed or add an external shock absorber.
