About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-10S
The AirTAC SAIJ200X270-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 260-270 mm from its 270 mm nominal stroke. As the largest bore in the series, it generates massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa. This makes it ideal for heavy-duty operations requiring exact end-position tuning without swapping hardware.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel retains standard ISO 15552 mounting dimensions, while the rear stopper allows up to 10 mm of retraction adjustment. Note that the adjuster acts only as a travel stop, not a load lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-10S Is Used
Heavy Press Tuning
Dial in the exact 260-270 mm end-stop during heavy press commissioning to accommodate material thickness variations without external shims.
Product Changeover
Quickly adjust the retraction point by up to 10 mm on automated lines when switching between similar but slightly different large product dimensions.
High-Force Positioning
Leverage the 15708 N push force at 0.5 MPa to move heavy pallets or molds into a precise final position before secondary operations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-10S the Right Cylinder?
Select this 200 mm bore cylinder when an application demands extreme force, such as 15708 N push at 0.5 MPa, combined with fine 10 mm end-position tuning during commissioning. If your setup requires less force, stepping down to a 160 mm bore yields 10053 N push at 0.5 MPa. Because the 270 mm stroke exceeds 300 mm? No, but for any stroke over 300 mm, external guides are recommended to manage side loads on the 40 mm rod. The PT tapered ports and G3/4 thread size match the bore standard.
An adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops for product changeovers. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For applications needing to hold a load without live air pressure, this cylinder is insufficient; you should consider the SAIL air-released lock or BSAI clamp-lock instead, as the SAIJ adjuster cannot hold loads.
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 SAIJ200BX270-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can achieve up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a 260-270 mm usable travel window. It functions as a mechanical stop to fine-tune the end position and is not a lock to hold the load without air pressure.
