The AirTAC AirTAC SDA100X70BH 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 SDA100X70BH is a double-acting, single-rod compact cylinder engineered to deliver massive thrust within a minimal axial footprint. By utilizing a riveted assembly that permanently joins the barrel, rear cover, piston, and rod, this 100mm bore unit achieves a remarkably short overall length compared to conventional round-body actuators. It generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, with a hard-anodized inner bore ensuring long service life.
This specific configuration includes a male M26x1.5 threaded piston rod (denoted by the B code) for robust mechanical load coupling, and FKM fluororubber seals (the H code) for enhanced thermal and oil resistance. The unit features PT3/8 air ports and relies on a fixed NBR bumper at each stroke end to absorb impact energy. Because this SKU lacks the S magnet code, it cannot support magnetic position sensing without altering the build.

Drives robust metal blank feeding mechanisms into large stamping presses, utilizing the 5497.8 N extend force at 0.7 MPa to push heavy steel coils reliably against hard stops.
Sweeps heavy filled cartons onto wooden pallets at the end of high-speed packaging lines, where the short riveted body saves valuable machine depth.
Applies high clamping pressure to hold thick automotive structural panels steady during robotic welding or forming operations.
When sizing this actuator, compare its 3927 N push force at 0.5 MPa against the neighboring SDA80, which provides 2513.3 N. Stepping up to this 100mm bore yields a 56% increase in thrust over the SDA80, making it the optimal choice when the smaller variant runs out of power. Based on the 0.5 MPa output, the safe working load is approximately 2356 N (about 60% of capacity), translating to a vertical lift capability of roughly 200.2 kg with a 2:1 safety margin. Confirm your ordering essentials: 100mm bore, 70mm stroke, PT3/8 port, male M26x1.5 rod thread, FKM seals, and no sensor magnet.
Keep in mind that a standard compact cylinder does not hold its position if air pressure is lost or the control valve is centered; the piston will drift. The fixed NBR bumper only decelerates the load near the stroke end and does not function as a locking brake. If your application requires static load holding upon pneumatic failure, you must integrate an external rod lock or a pilot-operated check valve into your circuit.
Quick checklist
This 100mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push at 0.7 MPa. The theoretical maximum push force is 801 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa, runs at speeds between 30-500 mm/s, and handles ambient temperatures from -20 to +70 C.
No. This model uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-energy cycles, you should slow the approach speed or mount an external shock absorber. Additionally, this specific SKU lacks a piston magnet, so it cannot accept AirTAC reed or electronic switches without changing to an S-designated variant.
