The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X30B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 30mm stroke). The through-rod resists twisting and lets you drive a tool on one end while a switch or dog reads position on the other — with identical force in both directions.
The AirTAC SDAD25X30B is a double-acting compact cylinder featuring a 25 mm bore and a 30 mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in both chambers. This geometry ensures push force equals pull force, delivering exactly 206.2 N at 0.5 MPa in each direction. The through-rod design inherently resists twisting, providing stable linear motion for symmetric loads.
Equipped with male M8x1.25 thread on both rod ends, this unit allows direct mounting of tooling on one side and a dog or fixture on the opposite side. The short body profile minimizes axial footprint where space is tight. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. This SKU lacks a piston magnet, so position sensing is not supported without switching to the -S variant.

Because a rod occupies both cylinder chambers, the effective area — and therefore the force — is identical in both directions. Specifications follow the official AirTAC SDAD datasheet.
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 kgf |
Force uses the annular (rod-side) area on both strokes, so extend and retract match. Actual usable force is lower than theoretical due to friction. Size with a safety margin.

Drives a dual-sided gripper where the equal 206.2 N extend and retract forces prevent part distortion during robotic pick and place.
Powers a precision scoring head that relies on the through-rod geometry to resist twisting torque without external linear bearings.
Mounts a male M8x1.25 thread die on the front rod and a limit dog on the rear rod to trigger external mechanical switches.
When sizing this actuator, evaluate the neighboring bores at 0.5 MPa. Stepping down to the SDAD20 yields 131.9 N, while stepping up to the SDAD32 provides 345.6 N. The 25 mm bore offers a calculated safe working load of roughly 124 N, which translates to a vertical lift capacity of about 10.5 kg with a 2:1 safety margin. Choose this model when your application demands balanced force and anti-rotation stability within a 30 mm stroke.
Confirm the 10 mm rod diameter and M5x0.8 air port suit your pneumatic layout. The male M8x1.25 rod threads on both ends require appropriate clearance for tooling. Note that a standard cylinder drifts when air pressure is lost or the valve is centered; the NBR bumper only decelerates the stroke end and does not function as a lock. For load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
The double-rod design provides equal force in both directions: 206.2 N at 0.5 MPa, 288.6 N at 0.7 MPa, and a theoretical maximum of 42 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod extends from both sides, allowing you to drive a tool on one end and mount a dog on the other. This specific model features male M8x1.25 threads on both rod ends. Note that it lacks a piston magnet, so it cannot trigger AirTAC reed or electronic switches without upgrading to the -S variant.
