The AirTAC AirTAC SDA63X15H Compact Cylinder | 63mm Bore FKM is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 15mm 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 SDA63X15H is a double-acting, single-rod compact cylinder engineered with a 63 mm bore and a 15 mm stroke. It generates 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. The -H designation indicates a fluororubber (FKM) seal variant, providing enhanced resistance to higher temperatures and oil exposure compared to standard NBR rubber. Its riveted assembly integrates the barrel, rear cover, and piston to drastically reduce axial mounting depth.
This model uses a 20 mm piston rod and PT1/4 ports. Instead of an adjustable air cushion, it relies on fixed NBR bumpers at both ends to decelerate the stroke. Because this specific SKU lacks the -S magnet code, it cannot support magnetic reed or electronic switches. For high kinetic energy loads, operators should add an external shock absorber to protect the short 15 mm stroke mechanism.

Short 15 mm ejection strokes inside hot mold environments where the FKM seal survives elevated ambient temperatures better than standard rubber.
Delivers 1558.6 N of extend force to seat or stamp small metal components within a tight machine footprint that excludes longer profile cylinders.
Applies over 1400 N of pull force at 0.5 MPa to fold heavy corrugated cardboard flaps rapidly on high-speed packaging lines.
When sizing this 63 mm bore actuator, consider stepping down to the SDA50, which provides 981.7 N of push at 0.5 MPa, or moving up to the SDA80, which yields 2513.3 N at the same pressure. The 1558.6 N output at 0.5 MPa translates to a safe working load of roughly 935 N (about 60 percent of capacity) and a vertical lift capability of approximately 79.4 kg with a 2:1 safety margin. Confirm your ordering essentials: 63 mm bore, 15 mm stroke, PT1/4 port, female M10x1.5 rod thread, and FKM seals. Note that a plain SDA cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; the fixed bumper only decelerates near the end of travel and acts as neither a lock nor a brake. To maintain vertical position holding without live pressure, an external rod lock or pilot-operated check valve is required.
Quick checklist
At 0.5 MPa, the push force is 1558.6 N and the pull force is 1401.5 N. At 0.7 MPa, the push is 2182.1 N and the pull is 1962.2 N. The theoretical maximum push force is 318 kgf at 1.0 MPa, which is the maximum operating pressure. The proof pressure is 1.5 MPa.
No, this specific SKU does not include the -S option, meaning it lacks a piston magnet and cannot trigger AirTAC reed or electronic switches. You would need the -S variant for position sensing. Additionally, it uses fixed NBR bumpers rather than an adjustable air cushion, so external shock absorbers are recommended for high-speed approaches.
