The AirTAC AirTAC SDA100X70SH 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 SDA100X70SH is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, this unit achieves a remarkably short overall length compared to conventional round-body designs. At 100 mm bore, it generates a substantial 3927 N push force at 0.5 MPa, making it suitable for high-impact positioning tasks.
This specific configuration includes a built-in piston magnet (-S) for position sensing and fluororubber (-H) seals for enhanced thermal and oil resistance. The 32 mm piston rod features a female M18x1.5 thread, while the body incorporates PT3/8 ports. End-of-travel deceleration is handled by a fixed NBR bumper at each end; because this is not an adjustable air cushion, operators should reduce approach speed or install external shock absorbers for high-energy loads.

Drives heavy lower-die holders into the staging area of an automotive stamping press, utilizing the 3927 N push force to shift substantial tooling masses within a confined floor footprint.
Sweeps filled corrugated cartons onto wooden pallets at the end of a packaging line, where the short riveted body prevents interference with adjacent conveyor structures.
Provides the robust upward knockout force required to free dense plastic injection molded parts from deep cavity molds, benefiting from the FKM seals in high-temperature environments.
Selecting the SDA100X70SH is appropriate when your mechanism requires massive output within a tight mounting envelope. If you need to step down to reduce physical size and force, the neighboring SDA80 bore provides 2513.3 N of push at 0.5 MPa. As the 100 mm bore is the largest in this series, there is no larger standard SDA option available. Based on the 3927 N push figure at 0.5 MPa, the computed safe working load is approximately 2356 N (utilizing a 60% safety margin), which translates to a vertical lift capacity of about 200.2 kg with a 2:1 factor.
When configuring your setup, verify that the 70 mm stroke, PT3/8 porting, and female M18x1.5 rod end meet your interface requirements. The -S magnet allows you to track position along the body grooves using an AirTAC reed or electronic switch. Remember that this compact actuator relies on live air pressure to maintain its place; if air is lost or the valve is centered, the piston will drift. To suspend a load securely without continuous pressure, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push force is 801 kgf at the 1.0 MPa operating pressure limit.
No, the piston will drift if air pressure is lost or the control valve is centered. The fixed NBR bumpers only decelerate the rod near the stroke endpoints and do not function as a braking lock. To suspend a load safely, you must add an external rod lock or a pilot-operated check valve.
