The AirTAC AirTAC SDA50X50B Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 50mm 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 SDA50X50B is a double-acting, single-rod compact cylinder engineered to deliver a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly short axial package, drastically reducing mounting depth where a conventional round-body actuator would be too bulky. The bore is hard-anodized and utilizes a two-way piston seal for reliable performance.
This specific SKU includes a male M18x1.5 thread on the Ø20 mm piston rod for robust load coupling. It operates on PT1/4 ports and relies on a fixed NBR bumper at each end to decelerate the stroke. Because this configuration lacks the -S magnet option, it cannot host AirTAC reed or electronic switches. Operating speed spans 30-500 mm/s across a 0.15-1.0 MPa pressure range.

Uses the 981.7 N extend force to push heavy wooden pallets sideways onto secondary packaging lines without requiring deep axial clearance.
Drives mechanical arms to fold large corrugated carton flaps, leveraging the male M18x1.5 rod thread for secure bracket attachment.
Raises lightweight product trays vertically, safely handling loads around 50 kg while benefiting from the space-saving riveted body design.
When sizing this actuator, 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. For this 50 mm bore, the computed safe working load is approximately 589 N (about 60% of the 981.7 N figure), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. Ensure your ordering essentials capture the 50 mm bore, 50 mm stroke, PT1/4 port, and the male M18x1.5 rod thread denoted by the B suffix. Keep in mind that a standard compact body does not hold its position if air pressure drops or the valve is centered; the piston will drift, and an external rod lock or pilot-operated check valve is required to secure a suspended load.
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.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a locking brake. For high energy impacts, add an external shock absorber. Additionally, this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S variant.
