Airtac SDA Ultra Thin Cylinder SDA50X25
The AirTAC SDA Ultra Thin Cylinder SDA50X25 is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 25mm stroke, PT1/4 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 SDA50X25
The AirTAC SDA50X25 is a double-acting single-rod compact cylinder delivering a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. Its riveted assembly joins the barrel, rear cover, piston, and rod into a very short axial package, saving valuable mounting depth where a longer round-body unit would fail. The 50 mm bore features a hard-anodized inner wall and a PT1/4 port to handle substantial pneumatic flow.
This specific SKU lacks a piston magnet, so it cannot host magnetic switches; add the -S option if you require reed or electronic sensing. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may need an external shock absorber. With a 20 mm rod and female M10x1.5 thread, it provides a robust coupling point for your 25 mm travel requirement.

Where the Airtac SDA Ultra Thin Cylinder SDA50X25 Is Used
Press-Fit Pin Insertion
Drives dowel pins into aluminum jigs using its 981.7 N extend force, with the 25 mm short stroke preventing over-travel during precise assembly tasks.
Carton Flap Folding
Actuates cardboard side flaps on a continuous packaging line, where the compact riveted body minimizes frame interference across dense conveyor layouts.
Is the Airtac SDA Ultra Thin Cylinder SDA50X25 the Right Cylinder?
When sizing this 50 mm bore, stepping down to the SDA40 yields 628.3 N of push force at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N.
Remember 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. To hold a vertical position securely without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 50 mm bore, 25 mm stroke, PT1/4 port, female M10x1.5 rod thread, and no 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 SDA50X25 FAQ
At 0.5 MPa this cylinder pushes with 981.7 N and pulls with 824.7 N. At 0.7 MPa the push increases to 1374.4 N and the pull to 1154.5 N. The theoretical maximum push is 200 kgf at the 1.0 MPa operating pressure limit.
No. This SKU has no piston magnet, so it cannot accept reed or electronic switches (order the -S variant for sensing). It uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion; add an external shock absorber for high-energy loads.
