The AirTAC AirTAC SDA50X10B Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 10mm 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 SDA50X10B is a double-acting single-rod compact cylinder engineered to deliver a robust 981.7 N of push force at 0.5 MPa. Its riveted assembly joins the barrel, rear cover, piston, and rod into a highly shortened unit, saving valuable axial mounting depth where a conventional round-body actuator would simply not fit. The 50 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable pneumatic operation.
This specific SKU is configured with a male-thread piston rod end (M18x1.5) for secure mechanical load coupling, paired with a 20 mm rod diameter to resist bending on short strokes. End-of-travel deceleration is handled by a fixed NBR bumper at each end rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorption. Because this model lacks the -S magnet option, it cannot host magnetic reed or electronic switches.

Provides a short 10 mm ejection stroke inside tight mold platens, utilizing the male M18x1.5 rod thread to securely attach custom stripper bolts.
Delivers rapid 981.7 N push at 0.5 MPa to tuck heavy corrugated cardboard flaps on high-speed packaging lines where axial depth is severely restricted.
Acts as a compact back-gauge stop in metal forming, holding position under pressure while the fixed NBR bumpers absorb the end-stop impact.
When sizing this actuator, consider 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. For the SDA50X10B, the 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. To finalize your order, confirm the 50 mm bore, 10 mm stroke, PT1/4 port, and the male M18x1.5 rod thread. Note that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. If your application must hold a load without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
This 50 mm bore cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, increasing to 1374.4 N push and 1154.5 N pull at 0.7 MPa. The theoretical maximum push is 200 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No. End-of-travel deceleration relies solely on fixed NBR bumpers, not an adjustable air cushion. Additionally, this SKU lacks the -S magnet option, so it cannot support magnetic reed or electronic switches; you would need the -S variant for position sensing.
