About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX700-30S
The AirTAC SAIJ200X700-30-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion control. It integrates a rear stopper mechanism that allows you to fine-tune the effective travel, providing a precise 670-700 mm usable stroke window from its 700 mm nominal length. Delivering immense thrust, it generates 28274N of push force and 15080N of pull force at 0.9 MPa. The SUS304 stainless steel rod provides superior corrosion resistance, while the integrated magnet enables direct compatibility with CMSE reed and DMSE electronic sensors.
Unlike fixed-stroke actuators, this model permits exact end-position calibration during commissioning without swapping hardware. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement. It is crucial to note that the rear adjuster acts strictly as a travel stop for deceleration and positioning, not as a locking device. The cylinder cannot hold a load without continuous live air pressure, requiring an external pilot-operated check valve or a SAIL lock cylinder for fail-safe load holding.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX700-30S Is Used
Heavy Press Tonnage Tuning
Dial in the exact 670-700 mm end-of-stroke position during commissioning to synchronize a massive 28274N pressing force without adding external mechanical shims.
Large Mold Changeover
Adjust the retract stop on the fly during product family changeovers, allowing a single cylinder to accommodate slight variations in large mold depths.
Oversized Pallet Indexing
Index heavy industrial pallets along a conveyor by fine-tuning the pusher stroke within the 30 mm adjustment window to match varying pallet lengths.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX700-30S the Right Cylinder?
Selecting this 200 mm bore actuator is ideal when an application demands immense thrust combined with variable end-stop positioning. If the 28274N push force at 0.9 MPa exceeds your actual payload requirements, stepping down to a 160 mm bore reduces the push force to 18095N while saving space and air consumption. Conversely, this SAIJ200X700-30-S is chosen over a fixed SAI cylinder when a machine setup requires a 670-700 mm travel window to dial in exact mechanical timing during product changeovers. To replace an ISO 15552 cylinder, match the 200 mm bore, 700 mm stroke, 30 mm adjustment, PT tapered ports, and the -S magnet specification.
Because this unit features a 700 mm stroke, the 40 mm diameter rod and M36x2 thread must be properly supported. Long unsupported strokes are highly susceptible to side-loading and buckling forces. Always use an external guide rail to prevent premature seal wear and ensure smooth operation. The mounting hardware is limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR foot and clevis brackets.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200BX700-30S FAQ
At the maximum operating pressure of 0.9 MPa, this 200 mm bore double-acting cylinder generates a push force of 28274N and a pull force of 15080N. At 0.5 MPa, it provides 15708N of push force and 15080N of pull force.
The rear adjuster acts as an external stopper that lets you shorten the effective travel by up to 30 mm. This creates a 670-700 mm usable stroke window, enabling fine-tuning of the end position at commissioning without replacing the cylinder. The adjuster is a stop, not a lock, and live air is required to hold the load.
