The AirTAC AirTAC SDA25X45SB Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 45mm 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 SDA25X45SB is a double-acting, single-rod compact cylinder engineered to deliver 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth, making it highly effective for machinery where a standard round-body unit would protrude too far. The 25 mm bore features a hard-anodized inner wall and a two-way piston seal for prolonged operational life.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, plus a male M8x1.25 thread (-B) on the 10 mm rod end for secure mechanical load coupling. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycling.

Actuates a cutting head assembly on an electronics depaneling machine, utilizing the 45 mm stroke and male M8 rod to precisely sever printed circuit boards without excessive axial footprint.
Drives the side flap folding mechanism on a continuous motion cartoning system, where the 245.4 N push force securely tucks flaps prior to sealing at speeds up to 500 mm/s.
Ejects small stamped metal pins from a progressive die set, using the integrated magnet and reed switch to confirm part release before the press cycle restarts.
When sizing this unit, evaluate your force requirements carefully: stepping down to the SDA20 provides 157.1 N of push at 0.5 MPa, while stepping up to the SDA32 yields 402.1 N. The SDA25X45SB yields a safe working load of roughly 147 N (about 60% of its 245.4 N capacity) and can vertically lift approximately 12.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 25 mm bore, 45 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and the integrated magnet. Remember that a standard compact cylinder drifts if air pressure drops or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake, so deploy a pilot-operated check valve or external rod lock if you must hold a suspended load.
Quick checklist
This 25 mm bore double-acting cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa, and 343.6 N push at 0.7 MPa. The theoretical maximum push force is 50 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30-500 mm/s.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston. It is not an adjustable air cushion. If your application runs at high speeds or involves heavy moving masses, you should add an external shock absorber or throttle the approach speed to prevent damage.
