The AirTAC AirTAC SDA25X15SB Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 15mm 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 SDA25X15SB 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 merges the barrel, rear cover, and piston into an exceptionally short axial footprint, conserving machine depth where conventional round bodies cannot fit. The 25 mm bore features a hard-anodized inner wall and a two-way piston seal for low-friction cycling across the 30-500 mm/s speed range.
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 for secure mechanical load coupling. End-stop deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning high-energy cycles may require an external shock absorber to prevent impact wear.

Uses the 15 mm stroke and 245.4 N push force to eject routed circuit boards from a routing fixture without stressing the male M8 tooling head.
Tucks small corrugated box flaps prior to sealing, leveraging the short 25 mm bore riveted body to fit within tight side-frame conveyor clearances.
Pushes light-gauge steel sheets against a hard stop for welding prep, relying on the built-in magnet and electronic switch to confirm part alignment.
When sizing this 25 mm bore unit, stepping down to the SDA20 yields 157.1 N of push at 0.5 MPa, while stepping up to the SDA32 provides 402.1 N, letting you fine-tune force to the exact load. At 0.5 MPa, the SDA25X15SB offers 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. To finalize your order, confirm the 15 mm stroke, M5x0.8 air port, the -S magnet requirement, and the -B male rod end.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops or the valve is centered—the piston will drift, and the fixed NBR bumper only decelerates near the stroke end without acting as a brake. If your application demands strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
At 0.5 MPa, this 25 mm bore cylinder provides 245.4 N of push force and 206.2 N of pull force. At 0.7 MPa, push increases to 343.6 N and pull to 288.6 N. The theoretical maximum push force is 50 kgf at the 1.0 MPa operating pressure limit.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion; for high-speed cycling, add an external shock absorber. Additionally, it does not hold position on air loss—the piston drifts, so an external rod lock or pilot-operated check valve is required for load holding.
