The AirTAC AirTAC SDA50X150B 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 SDA50X150B 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 assembly merges the barrel, rear cover, piston, and rod into a remarkably short footprint, saving valuable axial mounting depth in tight machinery layouts. The hard-anodized bore minimizes friction, while the integrated PT1/4 port ensures reliable pneumatic supply.
This specific SKU features a male M18x1.5 thread on the Ø20 mm piston rod for robust load coupling, and requires a non-standard 150 mm stroke that exceeds the 130 mm standard maximum for this bore, making it a made-to-order unit. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should reduce approach speeds or add external shock absorbers for high-energy loads. Because this configuration lacks the -S magnet option, it cannot host reed or electronic switches.

Provides the 981.7 N push required to fold heavy corrugated cardboard flaps on high-speed packaging lines, utilizing the male M18x1.5 rod thread for secure flap-arm linkage.
Actuates a routing gate to redirect heavy pallets along a conveyor network, where the short riveted body conserves floor space within dense transfer zones.
Drives the ejection plate to release molded plastic components, though the 150 mm non-standard stroke requires careful external guidance to prevent side-loading on the compact rod.
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 the SDA50X150B specifically, the 981.7 N output at 0.5 MPa translates to a safe working load of roughly 589 N (about 60% capacity) and a vertical lift capability of approximately 50 kg with a 2:1 safety margin. Confirm your ordering essentials: 50 mm bore, 150 mm non-standard stroke, PT1/4 port, no sensor magnet, and the male M18x1.5 rod thread. Note that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end and does not function as a locking brake; utilize an external rod lock or pilot-operated check valve if the application demands position holding.
Quick checklist
This 50 mm bore double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, 1374.4 N push and 1154.5 N pull at 0.7 MPa, with a theoretical maximum push of 200 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-speed cycles you should add external shock absorbers. Furthermore, it does not hold its load if air pressure drops, so an external rod lock or pilot-operated check valve is required for fail-safe positioning.
