The AirTAC AirTAC SDA32X70SBH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 70mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA32X70SBH is a double-acting, single-rod compact cylinder engineered with a 32 mm bore and 70 mm stroke. It provides a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. The short riveted body significantly reduces axial mounting depth compared to round-body units, saving valuable machine footprint. This specific configuration includes a male M10x1.25 piston rod end for secure mechanical coupling and an FKM (fluororubber) seal variant for enhanced thermal and oil resistance.
Grooves around the hard-anodized aluminum body accept AirTAC magnetic switches, and the integrated -S piston magnet enables position detection via a reed or electronic switch. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Operating speed spans 30-500 mm/s, and the PT1/8 port ensures reliable pneumatic flow for this 12 mm rod assembly.

Secures aluminum engine blocks during machining operations, utilizing the 402.1 N push force and FKM seals to withstand cutting fluid exposure.
Drives mechanical arms to fold corrugated box flaps at high cycling speeds, relying on the 70 mm stroke and fixed NBR bumpers for consistent end-stop positioning.
Actuates routing gates on package handling lines where the short riveted body minimizes axial intrusion into tight transfer zones.
When sizing this 32 mm bore unit, stepping down to the SDA25 yields 245.4 N of push force at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. For this model, a safe working load is approximately 241 N (about 60% of the 402.1 N figure), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 32 mm bore, 70 mm stroke, PT1/8 port, male M10x1.25 rod thread, magnetic piston, and FKM seals.
Remember that a standard compact cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift. The fixed bumper only decelerates the stroke near its end and acts neither as a lock nor a brake. If your application must maintain a vertical load without live pressure, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. At 0.7 MPa, the push increases to 563 N. The theoretical maximum push is 82 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles speeds of 30-500 mm/s, and uses a PT1/8 port.
No, the piston will drift if air is lost or the directional valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end; it is not a locking brake. To maintain position on a vertical load, you must install an external rod lock or a pilot-operated check valve.
