About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-75S
The AirTAC SAIJ200X270-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 195 to 270 mm. Delivering immense thrust, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa. This bore size utilizes a G3/4 port and a robust 40 mm rod to handle heavy industrial loads.
This specific SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. You can fine-tune the retract end-position at commissioning via the external stopper screw without swapping the cylinder. The extruded aluminum barrel includes sensor grooves on both sides, seamlessly accepting AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-75S Is Used
Heavy Press Tuning
Fine-tune the 195-270 mm travel window during heavy press commissioning to achieve exact material forming depths without adding external mechanical stops.
Product Size Changeover
Rapidly adapt automated machinery for different product lengths by dialing the rear adjuster screw, eliminating the need to physically swap out the entire cylinder.
High-Force Positioning
Leverage the 15708 N push force at 0.5 MPa to move and position massive workpieces, relying on the 40 mm SUS304 rod for rigidity in harsh environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-75S the Right Cylinder?
Select this 200 mm bore actuator when an application requires extreme force that smaller neighbors cannot provide, such as replacing a 160 mm bore cylinder that tops out at 10053 N push force at 0.5 MPa. The adjustable stroke is ideal for product-size changeovers on a line, allowing operators to dial in the exact end-stop mechanically. To match this cylinder for an ISO 15552 replacement, verify the 270 mm stroke, 75 mm adjuster, PT tapered port thread, and the -S magnet option.
Because the stroke is 270 mm, the 40 mm rod requires external guiding to prevent excessive side-loading on the seals. Remember that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither will hold the load without live air pressure. For true load-holding without continuous air, utilize an external rod lock or pilot-operated check valve. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
- ✓ 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 SAIJ200BX270-75S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum rated pressure of 1.0 MPa, it achieves a maximum push force equivalent to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the nominal 270 mm down to 195 mm. This allows precise end-position tuning at commissioning, but it functions only as a travel stop and does not lock the load without live air pressure.
