The AirTAC AirTAC SDA63X75B Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 75mm 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 SDA63X75B is a double-acting single-rod compact cylinder engineered to deliver a robust 1558.6 N push force at 0.5 MPa. Its riveted assembly keeps the overall axial length exceptionally short, saving valuable mounting depth in tight machinery footprints compared to conventional round-body units. This specific SKU is configured with a male M18x1.5 piston rod thread for secure mechanical load coupling.
The bore features a hard-anodized inner wall and a two-way piston seal operating at 30-500 mm/s. End-stop deceleration is handled strictly by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorption. Because this model lacks the -S magnet suffix, it cannot host reed or electronic switches for position sensing.

Drives ejection pins on a 150-ton injection molding press where the 75 mm stroke clears finished plastic parts, utilizing the short riveted body to fit within the tight mold platen envelope.
Pushes heavy timber pallets onto a secondary packaging line, applying the 1558.6 N extend force to overcome friction and redirect loads smoothly at operating speeds up to 500 mm/s.
Secures heavy cast iron engine blocks during CNC machining, using the male M18x1.5 rod end to thread directly into a custom jaw clamp for rigid workholding under 0.5 MPa air pressure.
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. Based on the 1558.6 N output, a safe working load is approximately 935 N (60% capacity), translating to a vertical lift capability of roughly 79.4 kg with a 2:1 safety margin. To finalize your order, confirm the 63 mm bore, 75 mm stroke, PT1/4 port, and the male M18x1.5 rod thread designated by the B option.
Keep in mind that a standard compact actuator will not hold a load if air pressure drops or the directional valve centers. The piston will drift, as the fixed NBR bumper only decelerates the stroke near its limits and acts purely as an end stop, never as a locking brake. If your application demands static holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 63 mm bore double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa. At 0.7 MPa, push increases to 2182.1 N. The theoretical maximum push force is 318 kgf at the 1.0 MPa pressure limit, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet, so it cannot host reed or electronic switches. You would need the SDA63X75BS variant for position sensing. Additionally, end-stop deceleration relies on a fixed NBR bumper, not an adjustable air cushion.
