About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-100
The AirTAC SAIJ200X750-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 650-750mm usable travel window. Delivering 15708N of push force at 0.5 MPa, it handles massive loads with precision. The PT tapered ports and SUS420J2 stainless steel rod provide excellent durability and corrosion resistance.
Unlike fixed-stroke SAI units, this model allows you to fine-tune the end position during commissioning without external stops. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and operates at 30-500 mm/s. The adjuster acts solely as a travel stop, so an external rod lock or SAIL cylinder is required for load-holding without live air.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-100 Is Used
Heavy Machinery Changeover
Dial in the 650-750mm travel window during product size changeovers on large assembly lines without fabricating new mechanical hard stops.
Large Press Feeding
Feeds heavy materials into a press, using the rear adjuster to fine-tune the retracted position for different material widths.
Heavy-Duty Positioning
Positions large structural components accurately, relying on the 15708N push force at 0.5 MPa to move substantial payloads smoothly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-100 the Right Cylinder?
Choose this 200mm bore when you need maximum thrust that smaller bores cannot provide, such as stepping up from a 160mm bore that yields 10053N at 0.5 MPa. The 100mm adjustment range is ideal for product changeovers on large machinery, letting you dial in the exact end-stop without swapping cylinders. At a 750mm stroke, the long unsupported piston rod is susceptible to side-loading; always use an external guide to prevent premature seal wear. To match this ISO 15552 interchangeable cylinder, specify: 200mm bore, 750mm stroke, 100mm adjustment, PT G3/4 port, mounting, and no magnet.
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 SAIJ200AX750-100 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster allows you to shorten the 750mm nominal stroke by up to 100mm, providing a usable travel window between 650mm and 750mm. This stopper only sets the travel end and does not hold the load without live air pressure.
