The AirTAC AirTAC SDA80X100H Compact Cylinder | 80mm Bore FKM is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 100mm 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 SDA80X100H is a double-acting single-rod compact cylinder engineered for heavy-duty pneumatics within a minimal axial footprint. Its riveted assembly shrinks the overall length compared to traditional round-body units, saving valuable machine mounting depth. Delivering a robust 2513.3 N push force at 0.5 MPa, this 80 mm bore actuator features a 25 mm piston rod and PT3/8 air ports. The H designation indicates a fluororubber (FKM) seal upgrade, ensuring superior resistance to higher temperatures and oily environments compared to standard NBR.
End-of-travel deceleration relies on a fixed NBR bumper at each end, which absorbs impact energy but is not a field-adjustable air cushion. Because this specific SKU lacks the S option, it has no piston magnet and cannot support reed or electronic switches. Operating speeds span 30-500 mm/s. For high kinetic energy loads approaching the maximum stroke, incorporating an external shock absorber or slowing the approach speed is strongly advised to prevent premature wear.

Drives heavy plastic part ejection plates in injection molding machinery, utilizing the 100 mm stroke and FKM seals to withstand residual heat and oily ambient conditions.
Elevates heavy steel coil blanks in automated press feed lines, safely handling loads near the 128.1 kg vertical lift threshold within tight column dimensions.
Actuates large pneumatic gating arms on high-speed pallet dispensing stations, where the short riveted body minimizes interference in congested conveyor zones.
When sizing this actuator, compare its 2513.3 N push force at 0.5 MPa against adjacent bores. Stepping down, the SDA63 provides 1558.6 N; stepping up, the SDA100 yields 3927 N. A practical safe working load is approximately 1508 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm bore, 100 mm stroke, PT3/8 porting, and the absence of a sensor magnet. This base configuration uses a female M14x1.5 rod-end thread.
Remember that a standard compact cylinder cannot hold a load if air pressure drops or the directional valve centers. The piston will drift, and the fixed bumper only decelerates the stroke near its end rather than locking the rod. If your application demands strict position holding, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 80 mm bore double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa. At 0.7 MPa, push increases to 3518.6 N. The theoretical maximum push force is 513 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include the S option, meaning it lacks a piston magnet and cannot trigger AirTAC reed or electronic switches. Additionally, it uses fixed NBR bumpers for end-stop deceleration rather than adjustable air cushions, so external shock absorbers may be needed for high-speed operations.
