Airtac SDA Ultra Thin Cylinder SDA32X40
The AirTAC Airtac SDA Ultra Thin Cylinder SDA32X40 is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 40mm 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.

About the Airtac SDA Ultra Thin Cylinder SDA32X40
The AirTAC SDA32X40 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 securely joins the barrel, rear cover, piston, and rod, yielding an exceptionally short axial footprint that drops right into machinery where standard round-body units protrude too far.
This specific configuration features a 32 mm bore, a 12 mm piston rod, and PT1/8 ports. End-of-travel deceleration is handled strictly by fixed NBR bumpers rather than adjustable air cushions, meaning operators should reduce approach speed or bolt on an external shock absorber for high-energy loads. Because this SKU lacks the -S suffix, it has no internal piston magnet and cannot host reed or electronic switches.

Where the Airtac SDA Ultra Thin Cylinder SDA32X40 Is Used
PCB Router Gating
Actuates routing machine gates to sort printed circuit boards, utilizing the 40 mm stroke and 402.1 N force to push panels into testing lanes without excessive axial bulk.
Carton Flap Folding
Drives the side flap folding arms on a continuous carton erecting line, where the short riveted body fits neatly between the conveyor frame belts.
Bearing Press Fixture
Presses small radial bearings into motor housings, safely handling the 20.5 kg vertical load margin while the fixed NBR bumper absorbs the final 40 mm travel impact.
Is the Airtac SDA Ultra Thin Cylinder SDA32X40 the Right Cylinder?
When sizing this 32 mm bore unit, stepping down to an SDA25 yields 245.4 N of push at 0.5 MPa, while stepping up to an SDA40 provides 628.3 N. For the SDA32X40, the 402.1 N output translates to a safe working load of roughly 241 N (operating at a 60% derating) or a vertical lift capacity of about 20.5 kg with a 2:1 safety margin. To finalize your order, confirm the 40 mm stroke, PT1/8 porting, and the female M6x1.0 rod-end thread. Keep in mind that a standard compact cylinder drifts if air pressure drops or the valve centers; the fixed bumper only slows the piston near the stroke end and will not lock the load, so add an external rod lock or pilot-operated check valve if position holding is critical.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDA Ultra Thin Cylinder SDA32X40 FAQ
At 0.5 MPa this cylinder provides 402.1 N of push force and 345.6 N of pull force. At 0.7 MPa the push increases to 563 N. The theoretical maximum push is 82 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must select the SDA32X40S variant which has the internal magnet for the body sensor grooves.
