The AirTAC SDA63X120B Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 120mm 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 SDA63X120B 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 minimizes axial mounting depth, offering a significantly smaller footprint than traditional round-body actuators while operating at speeds between 30-500 mm/s.
This specific SKU features a male M18x1.5 threaded piston rod end for robust load coupling and utilizes PT1/4 ports. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Secures machining pallets inside automated CNC cells, utilizing the 120 mm stroke to clear the work envelope during tool changes.
Actuates routing gates on high-throughput logistics conveyors, using the 1558.6 N push force to reliably redirect heavy parcels.
Drives the lower feed mechanism in small metal stamping presses, where the compact riveted body saves critical vertical machine space.
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 stepping up to the SDA80 for 2513.3 N. To order, confirm the 120 mm stroke, PT1/4 porting, and the male M18x1.5 rod thread. Note 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 if position holding is required.
Quick checklist
This double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, and 2182.1 N push at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. It operates on filtered air between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
No, this SKU uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion; external shock absorbers are recommended for high-energy loads. Additionally, it lacks the -S magnet option, so it cannot support reed or electronic switches, and it features a male M18x1.5 rod thread instead of the standard female end.
