The AirTAC AirTAC SDA63X25H Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 25mm 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 SDA63X25H is a double-acting single-rod compact cylinder engineered with a 63 mm bore and 25 mm stroke. Its riveted assembly significantly reduces axial mounting depth compared to traditional round-body units, providing a highly space-efficient footprint for tight machine layouts. Equipped with a fluororubber (FKM) seal, this variant offers enhanced thermal and oil resistance for demanding environments.
Delivering a robust 1558.6 N push and 1401.5 N pull at 0.5 MPa, this model relies on a fixed NBR bumper at each end to decelerate the piston near stroke termination. Because this SKU lacks the -S magnet option, it cannot support magnetic reed or electronic switches. The 20 mm piston rod features an M10x1.5 female thread, and the unit operates at speeds between 30-500 mm/s via PT1/4 ports.

Provides high-force ejection of plastic parts from molds where elevated ambient temperatures require FKM seal integrity.
Handles the heavy lateral shifting of empty pallets in automated packaging lines without demanding excessive axial space.
Secures heavy cast iron blocks during machining operations, utilizing the 1558.6 N extend force for rigid workholding.
When sizing this actuator, stepping down to the SDA50 yields 981.7 N of push force at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N at the same pressure. Based on the 1558.6 N output at 0.5 MPa, the safe working load is approximately 935 N (60% capacity), translating to a vertical lift capability of about 79.4 kg with a 2:1 safety margin. Be aware that a standard cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load; utilize an external rod lock or pilot-operated check valve for secure holding. To order, confirm your requirements for the 63 mm bore, 25 mm stroke, PT1/4 port, female rod thread, and FKM seals.
Quick checklist
This 63 mm bore cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and speeds of 30-500 mm/s.
No, the piston will drift if air pressure is lost or the directional valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a locking brake. To maintain position, you must integrate an external rod lock or a pilot-operated check valve.
