The AirTAC AirTAC SDA50X80BH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 80mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA50X80BH is a double-acting single-rod compact cylinder engineered with a 50 mm bore and an 80 mm stroke. It generates 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. This unit features a male M18x1.5 piston rod thread for robust load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance. The short riveted body significantly reduces axial mounting depth compared to standard round-body cylinders, conserving valuable machine footprint.
A fixed NBR bumper at each end manages end-stop deceleration rather than relying on an adjustable air cushion. Operating speeds span 30-500 mm/s, and the hard-anodized bore ensures long service life. Because this specific SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches; sensing requires the -S variant. For high kinetic energy cycles, adding an external shock absorber is advised to protect the compact structure.

Drives the folding mechanism on corrugated box erecting machinery, where the 80 mm stroke rapidly opens carton flaps prior to tape sealing.
Actuates a diverter gate on a end-of-line palletizer, using the 981.7 N push force to redirect heavy product lanes between packaging routes.
Pairs with the male M18x1.5 rod to push molded plastic parts out of a tool, benefiting from the FKM seals in high-temperature molding cells.
When sizing this 50 mm bore unit, consider stepping down to the SDA40, which provides 628.3 N of push force at 0.5 MPa, or moving up to the SDA63, which yields 1558.6 N at the same pressure. The SDA50X80BH achieves a safe working load of approximately 589 N (about 60% of its 981.7 N capacity) and can vertically lift around 50 kg with a 2:1 safety margin. Confirm your ordering essentials: 50 mm bore, 80 mm stroke, PT1/4 port, male M18x1.5 rod thread, and FKM seals. Note that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not act as a lock. To hold a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 981.7 N and the pull force is 824.7 N. At 0.7 MPa, the push force is 1374.4 N and the pull force is 1154.5 N. The theoretical maximum push force is 200 kgf at 1.0 MPa, which is the maximum operating pressure.
No, this specific SKU does not include the -S piston magnet, so it cannot host AirTAC reed or electronic switches. You must select the -S variant for sensing capabilities. Additionally, this model uses a fixed NBR bumper for end-stop deceleration, not an adjustable air cushion.
