About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-40
The AirTAC SAIJ200X270-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 230-270 mm without adding external stops. Built with a SUS304 stainless steel rod and PT tapered ports, it delivers 15708 N of push force at 0.5 MPa and 21991 N at 0.7 MPa, making it suited for moving heavy loads.
This model operates at speeds of 30-500 mm/s and relies on adjustable air cushions at both ends to decelerate the massive 3204 kgf maximum load. The rear adjuster functions strictly as a mechanical stop to set the end position, meaning it will not hold the load safely without live air pressure. For load-holding requirements, consider an external pilot-operated check valve or the AirTAC SAIL or BSAI locking cylinder series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-40 Is Used
Heavy Pressing Operations
Provides up to 21991 N of push force at 0.7 MPa for heavy-duty pressing, forming, and riveting tasks that require precise end-position tuning.
Product Changeovers
The 40 mm rear adjuster allows rapid adaptation of the 230-270 mm travel window during product size changes without replacing the entire cylinder.
Large Assembly Jigs
Handles massive fixture positioning on automated lines, relying on the robust 200 mm bore and SUS304 rod for high side-load resilience.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-40 the Right Cylinder?
Choose this 200 mm bore size when your application requires extreme thrust that smaller bores cannot provide, such as stepping down from a 200 mm bore to a 160 mm bore which drops the 0.5 MPa push force to 10053 N. The 40 mm adjustment range is ideal for product-size changeovers on a line, allowing operators to dial in the exact end-stop without physically swapping the cylinder. Because the total stroke is 270 mm, you should ensure proper external guidance to prevent excessive side-loading on the large M36x2 rod thread. This SAIJ cylinder uses the reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. It is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ200BX270-40 FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective travel window from 230 to 270 mm. It sets the end position but does not lock or hold the load without continuous air pressure.
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa the push force increases to 21991 N, with a maximum rated force of 3204 kgf at 1.0 MPa.
