The AirTAC AirTAC SDA80X45BH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 45mm 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 SDA80X45BH is a double-acting, single-rod compact cylinder engineered for heavy-duty pneumatics within a minimal axial footprint. Its riveted body assembly keeps overall length exceptionally short, saving valuable machine mounting depth where a conventional round-body unit would not fit. At 80 mm bore, it generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, operating at speeds between 30-500 mm/s.
This specific SKU includes a male M22x1.5 piston rod thread for robust mechanical coupling to your load and an FKM (fluororubber) seal variant for enhanced thermal and oil resistance. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Provides high-force ejection of molded plastic parts from heavy tooling, utilizing the 2513.3 N push capacity and FKM seals to withstand ambient heat.
Indexes heavy sheet metal backstops in fabrication machinery where the short riveted body minimizes axial protrusion into the work cell.
Drives vertical lifting platforms in end-of-line packaging, handling dynamic loads safely with its 25 mm piston rod and fixed NBR end bumpers.
When sizing this model, consider stepping down to the SDA63, which yields 1558.6 N of push at 0.5 MPa, or moving up to the SDA100, which provides 3927 N at the same pressure. For the SDA80X45BH, the safe working load is approximately 1508 N (about 60% of the 2513.3 N figure at 0.5 MPa), 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, 45 mm stroke, PT3/8 port, male M22x1.5 rod thread, and FKM seal. Note that a standard cylinder drifts when air is lost or a valve is centered; the fixed bumper only decelerates near the stroke end and does not function as a lock. To hold a load securely without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 80 mm bore 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, with a proof pressure of 1.5 MPa.
No. This model uses a fixed NBR bumper to decelerate at stroke end, which is not an adjustable air cushion. Additionally, because it lacks the -S magnet option, it cannot support AirTAC reed or electronic switches.
