The AirTAC AirTAC SDA50X110B Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 110mm 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 SDA50X110B 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. Featuring a 50 mm bore and a 110 mm stroke, it utilizes a hard-anodized inner wall and a two-way piston seal to ensure reliable linear motion within a minimal axial footprint. This specific SKU includes a male M18x1.5 piston rod thread for robust mechanical load coupling.
Because the riveted body integrates the barrel, rear cover, and piston into one short assembly, it saves substantial mounting depth compared to conventional round-body units. End-stopping is handled by a fixed NBR bumper rather than an adjustable cushion, meaning operators should slow the approach or add an external shock absorber for high-energy cycles. Note that this configuration lacks the -S magnet, so it cannot host reed or electronic switches.

Pushes heavy wooden pallets laterally across a packaging line using the 981.7 N extend force, fitting neatly within the conveyor frame depth.
Drives the 110 mm stroke to fold large corrugated carton flaps prior to tape sealing, relying on the fixed NBR bumper to absorb the end impact.
Actuates a 50 kg vertical lift gate on a sorting machine, achieving a 2:1 safety margin while the male M18x1.5 rod secures the hinge bracket.
When sizing this unit, compare its 981.7 N extend force at 0.5 MPa against adjacent bores: stepping down to the SDA40 yields 628.3 N, while stepping up to the SDA63 provides 1558.6 N. Based on the 981.7 N output, the safe working load is roughly 589 N (about 60% capacity), translating to a vertical lift capability of approximately 50 kg with a 2:1 safety margin. If your application requires position holding upon air loss, be aware the piston will drift; an external rod lock or pilot-operated check valve is necessary. To order, confirm the 50 mm bore, 110 mm stroke, PT1/4 port, male M18x1.5 rod thread, and no sensor magnet.
Quick checklist
At 0.5 MPa this cylinder provides 981.7 N push and 824.7 N pull. At 0.7 MPa it provides 1374.4 N push and 1154.5 N pull. The theoretical maximum push force is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
No, a plain SDA cylinder will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and acts purely as an end stop, never as a lock or brake. To maintain a vertical load without live pressure, you must install an external rod lock or a pilot-operated check valve.
