The AirTAC AirTAC SDA32X70S 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 SDA32X70S is a double-acting, single-rod compact cylinder engineered to deliver a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into an exceptionally short axial footprint, conserving valuable machine space where conventional round bodies cannot fit. The 32 mm bore features a hard-anodized inner wall and operates on a 70 mm stroke.
This specific unit includes the S option, meaning it has a built-in piston magnet designed for position detection using an AirTAC reed or electronic switch seated in the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, ensuring reliable stopping without requiring manual tuning. Operating speeds span from 30 to 500 mm/s.

Secures aluminum engine blocks during CNC machining, utilizing the 402.1 N extend force to maintain rigid positioning against cutting vibrations.
Pushes corrugated cartons from a main sorting line onto secondary packaging lanes with a 70 mm stroke and integrated electronic switch feedback.
Ejects molded plastic parts from an injection press tool, relying on the fixed NBR bumper to absorb the impact at the end of the extend cycle.
When sizing this actuator, evaluate your force requirements against adjacent bores: stepping down to the SDA25 provides 245.4 N of push at 0.5 MPa, while moving up to the SDA40 yields 628.3 N. Based on the 402.1 N output at 0.5 MPa, a safe working load is approximately 241 N (about 60% capacity), translating to a vertical lift capability of roughly 20.5 kg with a 2:1 safety margin. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load; utilize an external rod lock or pilot-operated check valve if position holding is mandatory. To order, confirm the 32 mm bore, 70 mm stroke, PT1/8 port, female M6x1.0 rod thread, and the required S magnet option.
Quick checklist
At 0.5 MPa, this 32 mm bore cylinder generates 402.1 N of push force and 345.6 N of pull force. At 0.7 MPa, the push increases to 563 N and the pull to 483.8 N. The theoretical maximum push force is 82 kgf at the 1.0 MPa operating pressure limit.
No, the piston will drift if air pressure is lost or the directional valve is centered. The fixed NBR bumper only decelerates the rod near the stroke endpoints and does not function as a braking lock. An external rod lock or pilot-operated check valve is required to suspend loads safely.
