The AirTAC Airtac SDA Ultra Thin Cylinder SDA100X140SB is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 140mm 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 SDA100X140SB is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, delivering a substantial 3927 N push force at 0.5 MPa. This specific configuration includes a built-in piston magnet (-S) for position sensing and a male M26x1.5 threaded piston rod (-B) for secure direct load coupling.
Because the 140 mm stroke exceeds the 130 mm maximum standard stroke for this 100 mm bore, this unit is provided as a non-standard, made-to-order configuration. Deceleration at the stroke ends relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. The hard-anodized bore and two-way piston seal ensure durable operation across the 30-500 mm/s speed range.

Drives heavy ejector pins in automotive plastic molding presses where the male M26x1.5 rod end threads securely into the ejector plate.
Executes short, high-force stamping and bending operations for sheet metal brackets, utilizing the 3927 N push capacity at 0.5 MPa.
Actuates robust diverter gates on heavy-duty pallet conveyors, relying on the 32 mm piston rod to handle substantial side-load resistance.
Selecting this 100 mm bore model provides a theoretical maximum push capacity of 801 kgf at 1.0 MPa. When sizing your system, stepping down to the SDA80 offers 2513.3 N of push force at 0.5 MPa, which may suffice for lighter loads while saving space. Conversely, the SDA100 represents the largest available bore in this series, yielding the highest force output in the family. Computed insights indicate a safe working load of roughly 2356 N (about 60% of the 3927 N figure at 0.5 MPa) and a vertical lift capacity of approximately 200.2 kg using a 2:1 safety margin.
When ordering, confirm the 100 mm bore, 140 mm non-standard stroke, PT3/8 port, and the -S/-B options. Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed NBR bumper only decelerates the piston near the end of travel and does not function as a locking brake. If your application must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 100 mm bore cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, increasing to 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push force is 801 kgf at the 1.0 MPa operating pressure limit.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. The -S option includes a built-in magnet compatible with AirTAC reed or electronic switches mounted in the body grooves, and the -B option provides a male M26x1.5 rod end.
