About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX240-100S
The AirTAC SAIJ200X240-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 140 to 240 mm. Delivering a substantial 15708 N of push force at 0.5 MPa, this massive 200 mm bore actuator is engineered for heavy-duty machinery requiring exact end-position calibration without external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the PT G3/4 port ensures high airflow for rapid cycling.
This variant integrates a SUS304 stainless steel rod for superior corrosion resistance and features an integrated magnet (-S) designed to trigger CMSE reed or DMSE electronic solid-state sensors. The rear adjuster functions strictly as a travel stop to fine-tune the retract position, meaning it does not lock or hold the load without live air pressure. For applications requiring true load-holding, a SAIL pneumatic lock or external pilot-operated check valve is necessary.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX240-100S Is Used
Heavy Press Tonnage Calibration
Dial in the exact 140-240 mm travel window during commissioning to set precise pressing distances on large metal forming equipment without adding external mechanical stops.
Product Line Changeover
Quickly adjust the retract end-position by up to 100 mm when switching a heavy-assembly line to accommodate a different product family size.
Large Fixture Alignment
Fine-tune the stroke end-limit on massive positioning fixtures, leveraging the 15708 N push force and SUS304 rod to handle substantial loads in harsh environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX240-100S the Right Cylinder?
Selecting this 200 mm bore actuator over a smaller neighbor, such as the 160 mm bore delivering 10053 N at 0.5 MPa, is necessary when your application demands up to 15708 N of push force. The 100 mm adjustment range is ideal for large-scale machine setups where product size changes require dialing in the retract distance during commissioning, completely avoiding the need to swap out a fixed-stroke SAI cylinder. When replacing an ISO 15552 cylinder, verify the 240 mm nominal stroke, 100 mm adjustment, PT G3/4 ports, and the -S magnet requirement.
Because the nominal stroke of 240 mm exceeds the 300 mm threshold requiring external guidance, and given the massive 40 mm rod diameter with M36x2 thread, this cylinder handles significant mechanical stress. However, long unsupported strokes still necessitate an external guide to prevent excessive side-loading. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR configurations.

- ✓ 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 SAIJ200BX240-100S FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can deliver up to 3204 kgf at its maximum 1.0 MPa pressure.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective travel from the 240 mm nominal stroke down to a minimum of 140 mm. It only sets the end-position and does not hold the load without continuous air pressure.
