The AirTAC AirTAC SDA63X30SB Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 30mm 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 SDA63X30SB is a double-acting, single-rod compact cylinder engineered to deliver 1558.6 N of push force at 0.5 MPa. Its riveted assembly securely joins the barrel, rear cover, piston, and rod, yielding an exceptionally short axial footprint where conventional round bodies cannot fit. The 63 mm bore houses a hard-anodized inner wall and a two-way piston seal, operating at speeds from 30 to 500 mm/s.
This specific configuration includes the S option for a built-in piston magnet, enabling position detection via an AirTAC reed or electronic switch seated in the body grooves. The B option equips the 20 mm rod with a male M18x1.5 thread for direct load coupling, while the PT1/4 ports supply air to both chambers. End-stops rely on a fixed NBR bumper that decelerates the piston rather than an adjustable air cushion.

Provides robust 1558.6 N push force to eject dense plastic parts from injection moulding tools, saving valuable axial depth inside the machine platen.
Actuates a heavy diverting arm on a packaging conveyor line, utilizing the male M18x1.5 rod thread for a rigid linkage and the 30 mm stroke to clear the belt path.
Secures heavy cast iron blocks during CNC machining, relying on the magnetic switch for confirmation before the cutting cycle begins.
When sizing this actuator, evaluate your neighbours: the SDA50 provides 981.7 N push at 0.5 MPa for lighter loads, while the SDA80 steps up to 2513.3 N if your application demands greater thrust. For the SDA63X30SB, a 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. Confirm your ordering essentials: 63 mm bore, 30 mm stroke, PT1/4 port, male M18x1.5 rod, and the integrated magnet.
Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centred. The fixed NBR bumper only decelerates the piston near the stroke end; it does not function as a lock or brake. If your machine must hold a vertical load without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa. At 0.7 MPa, it yields 2182.1 N push and 1962.2 N pull. The theoretical maximum push force is 318 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the stroke, not an adjustable air cushion. For high kinetic energy or rapid cycling, you should slow the approach speed or install an external shock absorber to prevent premature wear.
