The AirTAC AirTAC SDA80X70B 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 SDA80X70B is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust in a minimal axial footprint. It generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa. By utilizing a short riveted body assembly, this unit significantly reduces overall mounting depth compared to conventional round-body actuators, making it highly effective for machinery where space is strictly limited.
This specific configuration includes a male-thread piston rod end (M22x1.5) for secure mechanical load coupling, paired with a robust 25 mm piston rod and PT3/8 air ports. The bore is hard-anodized for longevity, and impact energy at the stroke extremes is managed by a fixed NBR bumper. Because this SKU lacks the -S magnet option, it cannot host magnetic position sensors.

Drives the ejection plate inside a plastic injection molding machine, utilizing the 2513.3 N push force to reliably strip finished parts from the die cavity.
Positions heavy metal blanks within a mechanical stamping press, taking advantage of the 70 mm stroke and male M22x1.5 rod end for rigid tooling attachment.
Actuates a vertical lift mechanism in an end-of-line palletizer, where the compact riveted body minimizes machine height while raising 128 kg loads.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, whereas stepping up to the SDA100 provides 3927 N. The SDA80X70B provides a computed safe working load of roughly 1508 N (about 60% of its 0.5 MPa capacity) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm bore, 70 mm stroke, PT3/8 porting, male M22x1.5 rod thread, and the absence of a sensor magnet.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near the end caps rather than locking the assembly. If your application demands position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this 80 mm bore cylinder provides 2513.3 N of push force and 2267.8 N of pull force. At 0.7 MPa, push increases to 3518.6 N. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions at speeds of 30-500 mm/s.
No. This model relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-energy cycles, you should add an external shock absorber. Additionally, this specific SKU lacks the -S magnet, so it cannot support reed or electronic switches.
