Airtac SDA Ultra Thin Cylinder SDA80X45
The AirTAC SDA Ultra Thin Cylinder SDA80X45 is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 45mm stroke, PT3/8 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 SDA80X45
The AirTAC SDA80X45 is a double-acting single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly shortened axial footprint, saving valuable machine depth where a conventional round-body unit would never fit. The bore is hard-anodized and utilizes a two-way piston seal for reliable operation.
This specific 80 mm bore configuration incorporates a 25 mm piston rod and PT3/8 air ports. End-stop deceleration is handled strictly by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact damage. Because this SKU lacks the -S option, it has no piston magnet and cannot support position sensing.

Where the Airtac SDA Ultra Thin Cylinder SDA80X45 Is Used
Injection Mold Ejection
Drives heavy mold ejection plates in plastic injection machinery where the short riveted body minimizes interference with the press platen.
Press Brake Tooling
Actuates heavy lower tooling clamps in metal fabrication presses, utilizing the 25 mm rod to manage substantial side-load resistance.
Is the Airtac SDA Ultra Thin Cylinder SDA80X45 the Right Cylinder?
When sizing this unit, compare its 2513.3 N push at 0.5 MPa against adjacent bores: stepping down to the SDA63 yields 1558.6 N, while stepping up to the SDA100 provides 3927 N.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed NBR bumper only decelerates the stroke end and acts as neither a lock nor a brake. To secure a suspended load, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 80 mm bore, 45 mm stroke, PT3/8 port, female M14x1.5 rod thread, and no sensor magnet.
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 SDA80X45 FAQ
This 80 mm bore double-acting cylinder provides a push force of 2513.3 N and a pull force of 2267.8 N at 0.5 MPa. At 0.7 MPa, the push increases to 3518.6 N. The theoretical maximum push force is 513 kgf at 1.0 MPa.
No, this specific SKU does not include the -S option, meaning it lacks a piston magnet and cannot support reed or electronic switches. You would need to specify the SDA80X45S variant to enable position sensing.
