The AirTAC AirTAC SDA32X85 Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 85mm 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 SDA32X85 is a double-acting single-rod compact cylinder engineered to deliver 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. Its riveted assembly integrates the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth compared to round-body alternatives, making it highly effective for space-constrained machinery footprints. The bore is hard-anodized and utilizes a two-way piston seal for reliable pneumatic performance.
This specific 32 mm bore configuration features a 12 mm piston rod and a PT1/8 air port. It relies on a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion. Because this SKU lacks the -S option, it has no piston magnet and cannot support magnetic position sensing. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.

Actuates routing flaps on logistics sorting lines, utilizing the 85 mm stroke to push cartons onto secondary chutes with 402.1 N of extend force.
Adjusts yarn guide arms dynamically in weaving equipment, where the short riveted body minimizes axial intrusion into the compact machinery frame.
Drives the mechanical arms that fold cardboard flaps on automated carton erecting machines, benefiting from the fixed NBR bumper to absorb end-stop impact.
When sizing this actuator, evaluate your force margins carefully. If you need less push, stepping down to the SDA25 provides 245.4 N at 0.5 MPa; if your application demands more power, stepping up to the SDA40 yields 628.3 N at 0.5 MPa. For the SDA32X85, 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. To order, confirm the 32 mm bore, 85 mm stroke, PT1/8 port, female rod-end thread (M6x1.0), and the absence of a magnet. Note that a plain cylinder drifts when air is lost or the valve is centered—the fixed bumper only decelerates near stroke end and does not function as a lock or brake. To hold a load securely without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
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, push increases to 563 N and pull to 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa, which is the maximum operating pressure.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You would need the -S variant (SDA32X85S) for position sensing. Additionally, it uses a fixed NBR bumper for end-stop deceleration, not an adjustable air cushion.
