About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-50
The AirTAC SAIJ200X700-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that creates a 650-700 mm usable travel window. Equipped with a robust 40 mm SUS420J2 stainless steel rod, it delivers massive thrust up to 28274 N at 0.9 MPa, making it ideal for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
Because the adjuster acts purely as a mechanical stop at the retract end, it allows precise end-position tuning during commissioning without adding external stops. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. For applications requiring the load to be held without live air pressure, this cylinder is not a lock; you should specify a SAIL or BSAI variant instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-50 Is Used
Heavy Machinery Setup
Dial in the 650-700 mm travel end-stop during heavy equipment assembly without machining custom external spacers.
Product Line Changeover
Quickly adjust the retract position to accommodate different large product sizes flowing down the manufacturing line.
Press Positioning
Fine-tune the 28274 N end-of-stroke force delivery precisely at commissioning for high-tonnage press operations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-50 the Right Cylinder?
Choose this 200 mm bore when you need exceptional force that smaller bores cannot provide, such as stepping up from a 160 mm bore that offers 18095 N push at 0.9 MPa. The 50 mm adjustment range is highly valuable for product changeovers, letting operators dial in the exact end-stop on the fly rather than swapping out a fixed-stroke SAI cylinder. With PT tapered port threads and a 40 mm rod, it handles substantial loads but requires external guidance on this 700 mm stroke to prevent side-loading damage. The operating speed is 30-500 mm/s.
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 SAIJ200AX700-50 FAQ
At 0.9 MPa operating pressure, this 200 mm bore cylinder provides a push force of 28274 N and a pull force of 15080 N. It can deliver a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 700 mm nominal stroke by up to 50 mm, resulting in a usable travel window of 650 to 700 mm. It does not lock the load without live air pressure.
