The AirTAC AirTAC SDA63X45SH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 45mm 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 SDA63X45SH is a double-acting, single-rod compact cylinder engineered to deliver 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. Its riveted body assembly merges the barrel, rear cover, piston, and rod into a highly integrated unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. The 63 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable service life.
This specific configuration includes the S option for a built-in piston magnet, allowing position detection via AirTAC reed or electronic switches seated in the body grooves. The H designation specifies a fluororubber (FKM) seal variant for enhanced thermal and oil resistance. End-of-stroke deceleration is handled by a fixed NBR bumper, which is not an adjustable air cushion. The Ø20 mm piston rod terminates in a male M18x1.5 thread, and the air supply connects via PT1/4 ports.

Provides robust ejection force for plastic injection molding machines, where the compact footprint fits tight mold bases and the FKM seals withstand elevated ambient heat.
Drives heavy mechanical arms to fold corrugated cardboard flaps on high-speed packaging lines, utilizing the 1558.6 N extend force to overcome carton stiffness.
Secures heavy cast iron blocks inside CNC machining centers, using the male M18x1.5 rod thread to attach custom clamping jaws and the magnetic sensor for closed-loop confirmation.
When sizing this 63 mm bore actuator, evaluate your force requirements against its neighbours: 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. For the SDA63X45SH, the computed safe working load is approximately 935 N (about 60% of the 1558.6 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centred; the fixed bumper only decelerates the stroke end and does not act as a lock. If your application demands position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 45 mm stroke, PT1/4 port, male M18x1.5 rod thread, magnet, and FKM seals.
Quick checklist
This double-acting 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. It operates on filtered air between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, the SDA series uses a fixed NBR bumper at each end to absorb impact energy; it is not an adjustable air cushion. For high-speed or high-mass loads, you should slow the approach speed or install an external shock absorber. Additionally, this model includes the S option for a piston magnet compatible with AirTAC reed or electronic switches.
