The AirTAC AirTAC SDA80X140S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm 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 SDA80X140S is a double-acting, single-rod compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. Its riveted assembly integrates the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth, offering a highly space-efficient footprint where conventional round-body units fail to fit.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, fitting neatly into the body's peripheral grooves. The 80mm bore utilizes a PT3/8 air port and a 25mm piston rod. Because the 140mm stroke exceeds the 130mm standard maximum for this bore size, this unit is manufactured as a non-standard, made-to-order configuration.

Drives heavy mold ejection plates in plastic injection machinery, utilizing the 2513.3 N extend force to reliably strip finished parts within confined press footprints.
Raises and lowers heavy palletizing forks in automated packaging lines, where the 128.1 kg vertical lift capacity and compact riveted body optimize vertical space.
Positions heavy sheet metal blanks in CNC press brakes, using the 140mm stroke to feed material deep into the forming area before cycling.
When sizing your actuation system, evaluate the neighboring bores to ensure optimal performance: stepping down to the SDA63 yields 1558.6 N push at 0.5 MPa, while the larger SDA100 provides 3927 N. The SDA80X140S provides a safe working load of roughly 1508 N (about 60% of its 0.5 MPa output) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. Keep in mind this unit lacks a position lock; if air pressure drops, the piston will drift, and an external rod lock or pilot-operated check valve is required to hold a load securely.
To finalize your order, verify these essentials: an 80mm bore, a 140mm non-standard stroke, PT3/8 porting, the integrated -S magnet, and a female M14x1.5 rod-end thread (male M22x1.5 available via option B). The fixed NBR bumpers decelerate the stroke ends but cannot be field-adjusted, so for high-energy cycles, add an external shock absorber.
Quick checklist
This double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, and 3518.6 N push at 0.7 MPa. The theoretical maximum push force is 513 kgf at 1.0 MPa, operating within a 0.15-1.0 MPa pressure range.
No, the SDA80X140S uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-speed or high-energy applications, you should slow the approach speed or install an external shock absorber.
