The AirTAC AirTAC SDA50X65BH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 65mm 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 SDA50X65BH 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 significantly reduces axial mounting depth compared to round-body units, saving valuable machine footprint. This specific configuration includes a male M18x1.5 piston rod end for secure mechanical load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The 50 mm bore features a hard-anodized inner wall and a fixed NBR bumper at each end to absorb end-stop impact. Because it lacks a piston magnet, this SKU cannot host magnetic switches; adding an -S code enables reed or electronic sensing. Operating between 30-500 mm/s, the cylinder relies on its bumpers for deceleration rather than an adjustable air cushion, so high-energy cycles may require external shock absorbers.

Drives the film carriage on stretch wrappers, utilizing the 65 mm stroke to position the roll precisely while the FKM seals resist warm operating environments.
Actuates a routing gate on high-speed logistics conveyors, where the 981.7 N push force easily redirects heavy cardboard cartons without axial bloat.
Pushes finished plastic parts out of molding tools, leveraging the male M18x1.5 rod end for robust mechanical attachment to the ejector plate.
When sizing this unit, stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N, allowing you to scale thrust precisely. The 981.7 N output translates to a safe working load of roughly 589 N (60% capacity) or a vertical lift of approximately 50 kg with a 2:1 safety margin. Confirm your ordering essentials: 50 mm bore, 65 mm stroke, PT1/4 port, male M18x1.5 rod thread, FKM seals, and no sensor magnet.
Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered. The fixed bumper only decelerates the piston near stroke end and does not function as a locking brake. If your application must hold a vertical load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 50 mm bore double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa. At 0.7 MPa, push increases to 1374.4 N. The theoretical maximum push is 200 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU lacks a piston magnet and cannot host reed or electronic switches. You would need to specify the -S option to activate the body sensor grooves. It also uses fixed NBR bumpers for deceleration, not an adjustable air cushion.
