The AirTAC AirTAC SDA50X150SB Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 150mm 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 SDA50X150SB 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 short riveted body significantly reduces axial mounting depth compared to traditional round-body units, saving valuable machine footprint in tight assemblies. This specific configuration includes a built-in piston magnet for position sensing alongside a male M18x1.5 threaded rod end for secure mechanical coupling.
Because the 150 mm stroke exceeds the 130 mm maximum standard stroke for this 50 mm bore, this unit is classified as non-standard and produced as a made-to-order item. The bore is hard-anodized and uses a two-way piston seal, while end-stop deceleration is handled strictly by a fixed NBR bumper rather than an adjustable air cushion. For high-energy cycles, operators should add an external shock absorber or slow the approach speed.

Actuates a routing flap on a packaging conveyor, utilizing the 981.7 N extend force to push loaded pallets onto a secondary track without requiring a long axial profile.
Raises lightweight tote bins in a vertical materials handling lift, where the 150 mm stroke elevates components between belt levels and the male M18x1.5 rod secures the lifting fork.
Drives the side flap folding mechanism on a corrugated box erector, taking advantage of the compact riveted body to fit within the narrow frame of the folding turret.
When sizing this actuator, evaluate your force requirements carefully: the SDA40 provides 628.3 N of push at 0.5 MPa, while the larger SDA63 offers 1558.6 N. The 50 mm bore here yields a safe working load of roughly 589 N (about 60% of its 981.7 N capacity) and can vertically lift approximately 50 kg with a 2:1 safety margin. Note that a plain compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load; holding a suspended load requires an external rod lock or pilot-operated check valve.
To order correctly, confirm this exact configuration: 50 mm bore, 150 mm non-standard stroke, PT1/4 port, built-in magnet for AirTAC reed or electronic switches, and the male M18x1.5 piston rod thread.
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 the maximum operating pressure of 1.0 MPa.
No, this model uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. Because this unit has a non-standard 150 mm stroke, you should add an external shock absorber or slow the approach speed to manage the increased kinetic energy.
