The AirTAC AirTAC SDA63X75BH 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 SDA63X75BH 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 merges the barrel, rear cover, piston, and rod into an ultra-short unit, drastically reducing axial footprint compared to conventional round-body designs. This specific configuration includes a male M18x1.5 piston rod end for secure mechanical load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The bore inner wall is hard-anodized to minimize friction and wear. End-stop deceleration is handled strictly by fixed NBR bumpers rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers. Because this SKU lacks the -S magnet option, it cannot support magnetic position sensing; adding an -S variant enables the use of reed or electronic switches fitted into the body grooves.

Drives ejection pins on a 150-ton injection molding press, utilizing the 75 mm stroke to safely clear the mold cavity under high ambient heat thanks to FKM seals.
Folds top flaps on corrugated shipping cartons in a high-speed packaging line, where the 1558.6 N extension force easily overcomes board stiffness.
Positions lower die rails on a CNC press brake, taking advantage of the short riveted body to fit within the tight lateral constraints of the machine frame.
When sizing this actuator, consider stepping down to the SDA50, which provides 981.7 N of push at 0.5 MPa, or moving up to the SDA80 for 2513.3 N at the same pressure. For the SDA63X75BH, the calculated safe working load is approximately 935 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Confirm your ordering essentials: 63 mm bore, 75 mm stroke, PT1/4 port, male M18x1.5 rod thread, and FKM seals.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates the stroke near its end without acting as a brake. If your application demands position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 63 mm bore double-acting cylinder provides a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 N. The theoretical maximum push is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and the operational speed spans 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support magnetic sensing. To use AirTAC reed or electronic switches in the body grooves, you must specify the -S option when ordering. Additionally, this model uses fixed NBR bumpers for end-stop deceleration, which are not adjustable and do not function as a locking brake.
