The AirTAC AirTAC SDA50X65H 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 SDA50X65H is a double-acting single-rod compact cylinder engineered with a 50 mm bore and 65 mm stroke. It generates 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. This specific SKU features an H designation, utilizing fluororubber (FKM) seals for enhanced resistance to higher temperatures and oil exposure. The hard-anodized bore and two-way piston seal ensure durable performance across a 30-500 mm/s speed range.
A short riveted body joins the barrel, rear cover, piston, and rod, drastically reducing axial mounting depth where a standard round-body unit will not fit. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke end; it is not an adjustable air cushion, so high-energy cycles may require an external shock absorber. This model lacks a piston magnet and therefore cannot support magnetic sensing, while the 20 mm rod uses an M10x1.5 female thread for load coupling.

Drives cardboard flap folders on high-speed palletizing lines where FKM seals withstand warm ambient conditions and the 981.7 N push force easily manipulates heavy corrugated materials.
Mounts directly inside tight machinery frames to eject plastic parts, leveraging the short riveted body to save axial depth while providing a 50 kg vertical lift capacity with a 2:1 safety margin.
Actuates routing gates on beverage conveyors, using the 65 mm stroke to shift product lanes rapidly without needing an adjustable air cushion thanks to the fixed NBR bumper.
When sizing this actuator, step down to the SDA40 which provides 628.3 N of push at 0.5 MPa, or step up to the SDA63 which yields 1558.6 N at the same pressure. For the SDA50X65H, a safe working load is approximately 589 N (about 60% of the 981.7 N figure), translating to a vertical lift capacity near 50 kg with a 2:1 safety margin. Confirm your ordering essentials: 50 mm bore, 65 mm stroke, PT1/4 port, FKM seals, female rod thread, and no sensor magnet. Note that a plain compact cylinder does not hold its load if air pressure drops or the valve is centered—the piston will drift, and the fixed bumper only decelerates near the stroke end, so an external rod lock or pilot-operated check valve is required to maintain position.
Quick checklist
This 50 mm bore double-acting cylinder provides 981.7 N push and 824.7 N pull at 0.5 MPa. At 0.7 MPa, push increases to 1374.4 N and pull to 1154.5 N. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and operating temperature spans -20 to +70 C.
No, a plain compact cylinder drifts when air is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not act as a lock or brake. To hold a load securely without live pressure, you must install an external rod lock or a pilot-operated check valve.
