The AirTAC AirTAC SDA50X25N Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 25mm 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 SDA50X25N is a double-acting, single-rod compact cylinder engineered to deliver 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for machinery where space footprint is critical. The 50 mm bore houses a 20 mm piston rod, and the hard-anodized inner wall ensures durable, low-friction operation.
This model relies on a fixed NBR bumper at each end to absorb end-stop impact rather than an adjustable air cushion. Because this SKU lacks the -S magnet code, it cannot directly host AirTAC reed or electronic switches. Operating pressure spans 0.15-1.0 MPa, and the unit supports a speed range of 30-500 mm/s across a 25 mm stroke.

Drives the folding mechanism on packaging lines to close corrugated box flaps securely before taping, utilizing the 25 mm stroke for rapid cycling.
Actuates a routing pop-up arm on a parcel conveyor to push 50 kg tote boxes onto a secondary spur without demanding excessive longitudinal frame clearance.
Provides a compact ejection push for small plastic parts in an injection molding cell, where the short body length preserves valuable tooling space.
When sizing this actuator, evaluate your force margins carefully. If you need less thrust, the SDA40 provides 628.3 N of push at 0.5 MPa; stepping up to the SDA63 yields 1558.6 N. For the SDA50X25N, the safe working load is approximately 589 N (about 60% of the 981.7 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. Confirm your ordering essentials: 50 mm bore, 25 mm stroke, PT1/4 port, female M10x1.5 rod thread, and no sensor magnet. Note that this cylinder cannot hold a load if air pressure drops—the piston will drift, as the fixed bumper only decelerates near the stroke end and does not act as a brake. For suspended loads, integrate an external rod lock or 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, push is 1374.4 N and pull is 1154.5 N. The theoretical maximum push is 200 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must select the -S option. Additionally, end-stops rely on a fixed NBR bumper rather than an adjustable cushion, so external shock absorbers are recommended for high-speed operations.
