The AirTAC AirTAC SDA80X45S 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 SDA80X45S is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial envelope. Utilizing a riveted assembly that joins the barrel, rear cover, and piston, it saves substantial mounting depth compared to conventional round-body units. At 80mm 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 unit includes a built-in piston magnet (-S) compatible with AirTAC reed or electronic switches, fitting cleanly into the body's magnetic grooves. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. The 25mm piston rod utilizes an M14x1.5 female thread, and air connections use a PT3/8 port.

Drives heavy plastic part ejection plates in injection molding machines, utilizing the 2513.3 N extend force to reliably strip finished components from deep tooling cavities.
Raises and lowers loaded pallets in automated packaging lines, where the short riveted body conserves vertical machine space without sacrificing lifting power.
Applies steady downward pressure for pressing bearings into automotive housings, relying on the 25mm rod to handle high axial loads during end-stop contact.
When sizing this 80mm bore 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 massive SDA100 yields 3927 N. Based on the 2513.3 N output at 0.5 MPa, the computed safe working load is roughly 1508 N (60% capacity), translating to a vertical lift capability of about 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80mm bore, 45mm stroke, PT3/8 port, female rod thread, and the required magnetic sensor option. Note that a plain compact cylinder drifts if air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. If your application must hold a load vertically without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 80mm bore cylinder outputs 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 is 513 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and it functions in environments from -20 to +70 C.
No, the SDA80X45S uses a fixed NBR bumper at each end to decelerate the piston near the stroke extremes. It is not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow down the approach speed. Additionally, the built-in magnet works with AirTAC reed or electronic switches for position sensing.
