The AirTAC AirTAC SDA50X110BH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 110mm 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 SDA50X110BH is a double-acting single-rod compact cylinder engineered for tight axial footprints. It delivers 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. This specific SKU is configured with a male M18x1.5 piston rod thread for robust mechanical coupling, and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance. Because it lacks a piston magnet, it cannot directly host magnetic position sensors.
The riveted body assembly significantly reduces overall length compared to conventional round-body units, making it highly effective for conserving machine mounting depth. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should moderate approach speeds or utilize external shock absorbers for high-energy loads. Operating speed spans 30-500 mm/s across a 0.15-1.0 MPa pressure range.

Drives cardboard flap folders on high-speed palletizing lines where the short riveted body conserves vertical Z-axis space without sacrificing the 981.7 N push required to crease heavy corrugated board.
Actuates a diverting gate on a beverage conveyor, using the 110 mm stroke to reroute glass containers while the FKM seals withstand washdown lubricants and ambient heat.
Pairs with an external shock absorber to eject plastic parts from an injection molding fixture, utilizing the male M18x1.5 rod for a rigid mechanical interface against the mold plate.
Selecting this 50 mm bore provides a theoretical maximum output of 200 kgf at 1.0 MPa, translating to a safe working load of roughly 589 N or a 50 kg vertical lift with a 2:1 safety margin. If your application requires less force, stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa; conversely, scaling up to the SDA63 provides 1558.6 N. To confirm your ordering essentials: this is a 50 mm bore with a 110 mm stroke, PT1/4 port, male M18x1.5 rod end, and FKM seals. Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock or pilot-operated check valve is necessary for strict load holding.
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, push is 1374.4 N and pull is 1154.5 N. The theoretical maximum push is 200 kgf at the 1.0 MPa operating pressure limit.
No, a plain double-acting cylinder will drift downward if air is lost or the directional valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a locking brake. An external rod lock or pilot-operated check valve is required to hold the load.
