Airtac SDA Ultra Thin Cylinder SDA32X45
The AirTAC Airtac SDA Ultra Thin Cylinder SDA32X45 is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 45mm 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 SDA32X45
The AirTAC SDA32X45 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 unites the barrel, rear cover, piston and rod into a highly shortened axial footprint, making it ideal for machinery where a traditional round-body unit would protrude too far. The 32 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable low-friction operation.
This specific 45 mm stroke configuration uses a 12 mm piston rod and PT1/8 air ports. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add an external shock absorber for high-energy loads. Because this SKU lacks the S option, it has no piston magnet and cannot host magnetic switches.

Where the Airtac SDA Ultra Thin Cylinder SDA32X45 Is Used
CNC Fixture Clamping
Provides 402.1 N of extend force at 0.5 MPa to secure aluminum housings inside CNC machining centers, where the short 45 mm stroke minimizes interference with the cutting tool path.
Carton Flap Folding
Drives folding arms on automated packaging lines to tuck corrugated box flaps prior to tape sealing, utilizing the compact riveted body to fit within tight conveyor side frames.
PCB Router Ejection
Pushes singulated printed circuit boards out of a routing station, using the 12 mm rod and fixed NBR bumper to safely decelerate the 45 mm stroke without damaging delicate board edges.
Is the Airtac SDA Ultra Thin Cylinder SDA32X45 the Right Cylinder?
When sizing this unit, consider stepping down to the SDA25, which provides 245.4 N of push force at 0.5 MPa, or moving up to the SDA40, which yields 628.3 N at the same pressure. At 0.5 MPa, the SDA32X45 offers a safe working load of roughly 241 N (about 60% of its rated push) and can vertically lift approximately 20.5 kg with a 2:1 safety margin. To confirm your ordering essentials: specify the 32 mm bore, 45 mm stroke, PT1/8 port, female M6x1.0 rod thread, and note that no magnet is present. If your mechanism must hold a load vertically during air loss or valve centering, the piston will drift; you must integrate an external rod lock or pilot-operated check valve, as the fixed bumper only decelerates near stroke end and acts as neither a lock nor a brake.
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 SDA32X45 FAQ
This double-acting 32 mm bore 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 on filtered air between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot host AirTAC reed or electronic switches. To add sensing capabilities, you must order the SDA32X45S variant. Additionally, end-stop deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, so external shock absorption is recommended for high-speed operations.
