The AirTAC AirTAC SDA50X130SB Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 130mm 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 SDA50X130SB 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 body design significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for machinery where space savings are critical. The unit operates at speeds between 30-500 mm/s and uses a hard-anodized aluminum bore to ensure long service life.
This specific configuration includes an S option for the built-in piston magnet, enabling position detection via an AirTAC reed or electronic switch fitted into the body grooves. The B option equips the 20 mm piston rod with a male M18x1.5 thread for straightforward load coupling. Stopping is handled by a fixed NBR bumper at each end rather than an adjustable cushion, which decelerates the piston near the stroke limits without acting as a physical lock.

Pushes cartons onto secondary packaging lines using the 130 mm stroke, relying on the 981.7 N extend force to overcome side friction without needing a long profile body.
Raises light-duty pallet stops where axial depth is restricted, utilizing the male M18x1.5 rod for a secure mechanical linkage to the gate mechanism.
Ejects formed sheet metal parts from lower dies, using the built-in magnet and an electronic switch to confirm full retraction before the press cycles.
When sizing this unit, evaluate stepping down to the SDA40, which provides 628.3 N of push at 0.5 MPa, or moving up to the SDA63, which yields 1558.6 N at the same pressure. Based on the 981.7 N push figure, the safe working load is approximately 589 N (about 60% capacity), translating to a vertical lift capability of roughly 50 kg with a 2:1 safety margin. Ensure your ordering essentials match this 50 mm bore, 130 mm stroke, PT1/4 port, male M18x1.5 rod thread, and the required magnetic piston.
Keep in mind that a standard double-acting cylinder cannot hold a load if air pressure drops or the directional valve is centered; the piston will drift, and the fixed NBR bumper only decelerates near the end of travel. If your application demands strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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. The theoretical maximum push force is 200 kgf at 1.0 MPa, which is the maximum operating pressure.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; it is not an adjustable air cushion. Furthermore, it does not hold position on air loss, so an external rod lock or pilot-operated check valve is required if the load must be prevented from drifting.
