The AirTAC AirTAC SDA100X65SB Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 65mm 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 SDA100X65SB is a double-acting single-rod compact cylinder engineered for heavy-duty automation within confined axial footprints. A riveted assembly unites the barrel, rear cover, piston, and 32 mm rod, yielding a substantial 3927 N push force at 0.5 MPa while conserving machine depth. The bore is hard-anodized and utilizes a two-way piston seal, operating reliably at speeds between 30 and 500 mm/s.
This specific configuration includes a built-in piston magnet (-S) compatible with AirTAC reed or electronic switches, fitting neatly into the body's sensor grooves. The -B option specifies a male M26x1.5 threaded piston rod end for secure mechanical load coupling. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy impacts.

Drives heavy ejector pins on a 200-ton injection molding press, utilizing the 3927 N extend force to strip dense plastic parts from the tool cavity.
Positions thick steel back-gauge stops on a CNC press brake, where the 32 mm male-threaded rod securely mounts heavy stop fingers without deflection.
Raises heavy layer-forming platens in end-of-line packaging machinery, taking advantage of the short riveted body to minimize vertical tower height.
Selecting the SDA100X65SB provides a theoretical maximum push of 801 kgf at 1.0 MPa, with a computed safe working load around 2356 N (roughly 60% of the 0.5 MPa figure) and a vertical lift capacity near 200.2 kg using a 2:1 safety margin. If your application requires slightly less force, stepping down to the SDA80 yields 2513.3 N push at 0.5 MPa; as the largest bore in the series, there is no larger standard SDA option. Be aware that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near stroke end rather than locking the load. For position holding, integrate an external rod lock or pilot-operated check valve. Confirm your ordering essentials: 100 mm bore, 65 mm stroke, PT3/8 port, male M26x1.5 rod thread, and the integrated magnet.
Quick checklist
This 100 mm bore model 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, with a theoretical maximum push of 801 kgf at 1.0 MPa.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. For high-speed or high-mass loads, you should slow the approach speed or install an external shock absorber.
