The AirTAC AirTAC SDA63X15SB Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 15mm 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 SDA63X15SB is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa within a minimal axial footprint. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, making it highly effective for tight machine layouts. The unit includes a built-in piston magnet (-S) for position detection and a male M18x1.5 threaded rod end (-B) for secure load coupling.
This 63 mm bore model relies on a fixed NBR bumper at each stroke end to absorb impact energy rather than an adjustable air cushion. Operating at speeds between 30 and 500 mm/s, it features a hard-anodized bore and a 20 mm piston rod. For high-energy cycles, adding an external shock absorber is recommended to prevent premature wear.

Drives short-stroke ejector pins in plastic injection molding machines, utilizing the 1558.6 N push force to reliably free finished parts from the tool cavity.
Folds heavy corrugated cardboard flaps on automated packaging lines, where the compact riveted body conserves valuable floor space along the conveyor.
Acts as a robust stopper gate in palletizing stations, using the male M18x1.5 rod thread to securely mount a contact block that halts incoming pallets.
When sizing this model, evaluate your force requirements carefully: the SDA50 provides 981.7 N of push force at 0.5 MPa, while the larger SDA80 steps up to 2513.3 N at the same pressure. The SDA63X15SB offers a safe working load of roughly 935 N (about 60% of its 1558.6 N capacity) and can vertically lift approximately 79.4 kg with a 2:1 safety margin. Ensure you specify the 63 mm bore, 15 mm stroke, PT1/4 port, male M18x1.5 rod thread, and the required magnetic switch. Note that a standard cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the end of travel and does not function as a locking brake. If your application requires strict position holding, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 1558.6 N of push force and 1401.5 N of pull force. At 0.7 MPa, the push increases to 2182.1 N and the pull to 1962.2 N. The theoretical maximum push force is 318 kgf at 1.0 MPa.
No, the SDA63X15SB uses a fixed NBR bumper at each end to decelerate the piston, which is not field-adjustable. It is not an adjustable air cushion. For high-speed or high-energy applications, you should slow the approach speed or install an external shock absorber.
