The AirTAC SDA50X75B Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 75mm 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 SDA50X75B is a double-acting single-rod compact cylinder engineered to deliver a substantial 981.7 N push force at 0.5 MPa. Utilizing a short riveted body assembly, it drastically reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint in tight spaces. The hard-anodized bore and two-way piston seal ensure durable, long-lasting operation.
This specific configuration includes a male M18x1.5 piston rod thread for robust mechanical coupling to your load. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorbers.

Drives the vertical lifting arm in a packaging palletizer, utilizing the 981.7 N push force to elevate 50 kg cartons smoothly within a compact frame.
Mounts directly onto an injection molding press to eject finished plastic parts, where the male M18x1.5 rod thread securely attaches the knockout plate.
Actuates a sorting diverter on a logistics conveyor line, benefiting from the short riveted body to fit within narrow transfer chute clearances.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA40 reduces the push output to 628.3 N at 0.5 MPa, whereas stepping up to the SDA63 increases it to 1558.6 N at 0.5 MPa. For this SDA50X75B model, confirm your ordering essentials: 50 mm bore, 75 mm stroke, PT1/4 port, male M18x1.5 rod thread, and no piston magnet.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end without acting as a lock. If your application demands position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 50 mm bore double-acting cylinder provides 981.7 N push and 824.7 N pull at 0.5 MPa. At 0.7 MPa, it yields 1374.4 N push and 1154.5 N pull. The theoretical maximum push force is 200 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No. This SKU lacks the -S option, so it has no piston magnet and cannot support reed or electronic switches. Additionally, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion; for high kinetic energy loads, add an external shock absorber.
