The AirTAC AirTAC SDA80X70BH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm 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 SDA80X70BH is a double-acting compact cylinder engineered for heavy-duty pneumatics within a minimal axial footprint. Its riveted assembly merges the barrel, rear cover, and piston to conserve machine space where conventional round-body units fail to fit. Delivering 2513.3 N of push force at 0.5 MPa, this 80 mm bore unit is built for rigorous actuation.
This specific configuration includes a male M22x1.5 piston rod end for robust mechanical coupling and FKM seals for enhanced thermal and oil resistance. The unit relies on a fixed NBR bumper at each stroke end for deceleration rather than an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot support magnetic position sensing.

Drives heavy ejector pins in plastic injection molding machinery, utilizing the 2513.3 N push force to reliably break loose dense molded parts from the cavity.
Positions heavy gauge steel coils into progressive stamping presses, where the compact riveted body minimizes axial obstruction along the feed line.
Raises and lowers lowerator arms in automated packaging lines, moving loads up to 128.1 kg vertically while maintaining a tight machine envelope.
When sizing this actuator, evaluate your force margins carefully. Stepping down, the SDA63 provides 1558.6 N of push at 0.5 MPa, whereas stepping up to the SDA100 yields 3927 N. Based on the 2513.3 N output at 0.5 MPa, the computed safe working load is roughly 1508 N (applying a 2:1 factor), translating to a vertical lift capacity of about 128.1 kg. Remember that a standard compact cylinder drifts when air pressure drops or the valve centers; the fixed bumper only slows the piston near the end of travel and does not function as a locking brake. To suspend a load safely without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 80 mm bore, 70 mm stroke, PT3/8 port, male M22x1.5 rod thread, and FKM seals.
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, the push increases to 3518.6 N. The theoretical maximum push is 513 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operational speed range is 30-500 mm/s.
No, this specific SKU lacks the internal piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the -S option for sensing capabilities. Additionally, end-stop deceleration is handled strictly by a fixed NBR bumper, not an adjustable air cushion, so external shock absorbers are recommended for high-energy cycles.
