About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX145-30S
The AirTAC SAIJ200X145-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 115-145 mm usable travel window by allowing you to dial back the 145 mm nominal stroke by up to 30 mm. In the 200 mm bore class, it delivers a robust 15708 N push force at 0.5 MPa and 21991 N at 0.7 MPa.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop for end-position tuning during commissioning; it does not hold the load without live air. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set omits FB, CA, CB, and CR options.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX145-30S Is Used
Heavy Press Tuning
Dial in the exact 115-145 mm end-stop for heavy pressing operations without physically swapping out the cylinder.
Product Changeover
Quickly adjust the retract position on packaging lines when handling different product sizes or stack heights.
Machine Setup
Fine-tune the end-of-travel position during initial machine commissioning to perfectly time sequential motions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX145-30S the Right Cylinder?
Choose this 200 mm bore when your application requires heavy thrust up to 15708 N at 0.5 MPa, stepping up from a 160 mm bore that provides 10053 N. The adjustable stroke is ideal for fine-tuning end positions during machine setup or product changeover without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, this cylinder is insufficient—the adjuster is only a stop—so consider an AirTAC SAIL or BSAI series instead.
To match this ISO 15552 interchangeable cylinder for a replacement, verify the 200 mm bore, 145 mm stroke, 30 mm adjustment range, PT tapered port threads, and the -S magnet option. The operating speed reaches 30-500 mm/s, and with a 145 mm stroke, side-loading is moderate, but external guides are recommended if heavy lateral loads are present.
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 SAIJ200BX145-30S 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 0.7 MPa, the push force increases to 21991 N.
The rear adjuster allows you to shorten the 145 mm nominal stroke by up to 30 mm, creating a usable travel window of 115-145 mm. It functions as a mechanical stop for end-position tuning and does not lock or hold the load without live air pressure.
