The AirTAC SDA63X50H Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 50mm 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 SDA63X50H is a double-acting, single-rod compact cylinder featuring a 63mm bore and 50mm stroke. It generates 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. This H-suffix variant utilizes a fluororubber (FKM) seal for enhanced thermal and oil resistance. The riveted unibody design integrates the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth where a larger round-body unit would fail to fit.
A 20mm piston rod couples to loads via an M10x1.5 female thread, with a PT1/4 port managing air supply. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke termination; it is not an adjustable air cushion. Because this specific SKU lacks the S option, it has no piston magnet and cannot support position sensing.

Secures heavy cast iron engine blocks during machining operations, utilizing the 1558.6 N extend force to maintain rigid positioning against cutting forces.
Indexes empty wooden pallets into high-speed filling lines, where the compact riveted body saves valuable axial space within tight conveyor framing.
When sizing this unit, stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N. Confirm your ordering essentials: 63mm bore, 50mm stroke, PT1/4 port, female rod thread, and FKM seals.
Note that a standard compact actuator will not hold a load if air pressure drops or the valve is centered. The piston will drift, as the fixed bumper only decelerates near the stroke end rather than acting as a locking brake. To suspend a load safely without live pressure, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This double-acting cylinder outputs 1558.6 N push and 1401.5 N pull at 0.5 MPa. At 0.7 MPa, push increases to 2182.1 N and pull to 1962.2 N. The theoretical maximum push is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a speed of 30-500 mm/s.
No, this specific SKU lacks the S option, meaning it has no piston magnet and cannot trigger AirTAC reed or electronic switches. You would need the SDA63X50HS variant for position sensing. Additionally, end stopping uses a fixed NBR bumper, not an adjustable cushion.
