The AirTAC AirTAC SDA100X45B 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 SDA100X45B is a double-acting single-rod compact cylinder engineered for high-force tasks within a minimal axial footprint. It delivers a substantial 3927 N push and 3524.9 N pull at 0.5 MPa, achieving a theoretical maximum push of 801 kgf at 1.0 MPa. The riveted unibody design integrates the barrel, rear cover, piston, and rod to drastically reduce mounting depth where standard round-body units fail to fit.
This specific configuration includes the B option, providing a male M26x1.5 thread on a robust 32 mm piston rod for secure mechanical load coupling. The bore features a hard-anodized inner wall and operates on PT3/8 ports. End-stop deceleration relies strictly on fixed NBR bumpers rather than adjustable air cushions, meaning high-energy cycles may require external shock absorbers to prevent impact damage.

Provides the heavy 3927 N extend force needed to eject thick metal blanks from a progressive stamping die, utilizing the short 45 mm stroke to save axial press depth.
Breaks loose large industrial plastic injection molds during the initial separation phase, where the male M26x1.5 rod end securely threads into the mold plate.
Raises loaded 200 kg pallets in a compact vertical lift station, relying on the 32 mm rod to handle the high side-load resistance during the initial lift breakaway.
Selecting this 100 mm bore model provides immense thrust, but sizing both ways ensures optimal performance. Stepping down to the SDA80 yields 2513.3 N push at 0.5 MPa, which is often sufficient if your payload is lighter and space is extremely restricted. Since the SDA100 is the largest available bore in this series, there is no larger step up within the SDA family for higher force demands. Based on the 3927 N push figure, the computed safe working load is approximately 2356 N (about 60% capacity), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin.
When integrating this unit, remember that a plain compact cylinder does not hold its load if air pressure drops or the directional valve is centered; the piston will drift, and the fixed NBR bumper only decelerates near the stroke end rather than locking the position. For suspended or vertical loads, an external rod lock or pilot-operated check valve is required. Confirm your ordering essentials: 100 mm bore, 45 mm stroke, PT3/8 port, no sensor magnet, and the male M26x1.5 rod thread.
Quick checklist
At 0.5 MPa, the push force is 3927 N and the pull force is 3524.9 N. At 0.7 MPa, the push force is 5497.8 N and the pull force is 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and the operational speed range is 30-500 mm/s.
No, this specific SKU does not include the -S option, meaning it lacks a piston magnet and cannot trigger AirTAC reed or electronic switches. If your application requires position feedback, you must select the -S variant to enable magnetic sensing capabilities.
