The AirTAC AirTAC SDA25X80 Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 80mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA25X80 is a double-acting, single-rod compact cylinder engineered to deliver 245.4 N of push force at 0.5 MPa. Its short, riveted body design significantly reduces axial mounting depth, making it ideal for machinery where space is restricted. The unit features a hard-anodized bore and a two-way piston seal for reliable pneumatic performance.
This model includes an 80 mm stroke and a 10 mm piston rod. It relies on a fixed NBR bumper at each end to decelerate the stroke, rather than an adjustable air cushion. Without a piston magnet, this specific SKU cannot support magnetic sensing; adding an -S option is required for reed or electronic switch integration.

Pushes small cartons between sorting lanes on a packaging conveyor using a safe working load of 147 N.
Adjusts thread tensioning guides on automated weaving equipment where minimal axial mounting depth is required.
Secures printed circuit board panels during routing operations, utilizing the 80 mm stroke to clear the work area.
When sizing this actuator, evaluate your force margins: the SDA20 provides 157.1 N push at 0.5 MPa, while the SDA32 offers 402.1 N. Based on the 245.4 N output, the safe working load is roughly 147 N, allowing a vertical lift of about 12.5 kg with a 2:1 safety margin. If your mechanism must hold a load vertically during air loss, note that this cylinder will drift, as the fixed bumper only decelerates near stroke end and acts as neither a lock nor a brake. To secure the position, an external rod lock or pilot-operated check valve is required.
Confirm your ordering essentials for this SKU: 25 mm bore, 80 mm stroke, M5x0.8 port, female M5x0.8 rod-end thread, and no sensor magnet. For high-speed cycles, consider slowing the approach or adding an external shock absorber since the NBR bumper is not field-adjustable.
Quick checklist
This 25 mm bore cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa, or 343.6 N push and 288.6 N pull at 0.7 MPa. The theoretical maximum push is 50 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU lacks a piston magnet and cannot trigger sensing. You must select the -S option to enable reed or electronic switch integration. Additionally, it uses a fixed NBR bumper for end-stop deceleration, not an adjustable air cushion.
