The AirTAC AirTAC SDA32X70H 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 SDA32X70H is a double-acting, single-rod compact cylinder engineered with a 32 mm bore and 70 mm stroke. It generates 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. This specific SKU includes an H designation, meaning it uses fluororubber (FKM) seals for enhanced resistance to higher temperatures and oily environments, while retaining the standard operating pressure range of 0.15-1.0 MPa.
Built with a short riveted body, this unit drastically reduces axial mounting depth compared to conventional round-body cylinders, making it ideal for space-constrained machinery. The hard-anodized bore houses a two-way piston seal, and deceleration at the stroke ends is handled by a fixed NBR bumper. Note that this configuration lacks a piston magnet, so it cannot support magnetic position sensing without switching to an S-option variant.

Actuates tool indexing arms in enclosed machining centers where the FKM seals withstand elevated ambient heat and lubricant mist.
Drives the sealing jaw on packaging lines for carton closure, utilizing the 402.1 N push force to secure flaps through adhesive curing zones.
Pivots sorting gates on high-speed parcel conveyors, benefiting from the short riveted body to minimize protrusion into tight transfer zones.
When sizing this 32 mm bore actuator, consider stepping down to an SDA25 if your load requires less force, which provides 245.4 N of push at 0.5 MPa. If your application demands more power, the larger SDA40 offers 628.3 N at the same pressure. For this 70 mm stroke model, the 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. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; achieving true position holding requires adding an external rod lock or a pilot-operated check valve.
To finalize your order, confirm the 32 mm bore, 70 mm stroke, PT1/8 port size, and the female M6x1.0 rod-end thread. Because this is the H seal variant, it is specifically configured for harsher thermal and chemical exposure. The 12 mm piston rod is designed for direct coupling but requires careful alignment to avoid side loading.
Quick checklist
This 32 mm bore double-acting cylinder provides 402.1 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 563 N and pull to 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa, which is the maximum operating pressure.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not act as a locking brake. To maintain a vertical load without live pressure, you must install an external rod lock or a pilot-operated check valve.
