About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-75
The AirTAC SAIJ200X1000-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa, to handle heavy industrial loads. The built-in rear stopper allows you to fine-tune the effective travel window down from the 1000mm nominal stroke to a 925-1000mm range, perfect for dialing in final end positions without adding external stops.
Equipped with a SUS420J2 stainless steel rod and a PT tapered port, this unit omits the FB, CA, CB, and CR mounting accessories, retaining the Basic, FA, LB, TC, FTC, TCM1, and TCM2 set. It features variable air cushions at both ends to decelerate the large 200mm piston smoothly across its 30-500 mm/s speed range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-75 Is Used
Heavy Press Changeovers
Dial in the 925-1000mm travel window during heavy press setups to accommodate varying material thicknesses without physically replacing the cylinder.
Large Pallet Positioning
Fine-tune the retract end-position on oversized conveyor lines to adjust stopper locations for different pallet dimensions quickly.
Heavy Assembly Tuning
Achieve precise end-of-strike positioning for massive components by turning the rear screw, avoiding the need to bolt on secondary external stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-75 the Right Cylinder?
Choose this 200mm bore model when your application requires up to 3204 kgf at 1.0 MPa, stepping up from a 160mm bore that yields 18095N at 0.9 MPa. The adjustable 75mm stroke window is ideal for product-size changeovers on a line, letting you reposition the end-stop at commissioning rather than swapping out a fixed-stroke SAI cylinder.
Because the nominal stroke is 1000mm, the 40mm rod and M36x2 thread will not safely support high side loads without an external guide. Remember that the rear adjuster and air cushions act only as travel stops and deceleration devices; they do not hold the load without live air. For true load-holding without pressure, use an external rod lock or pilot-operated check valve.
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 SAIJ200AX1000-75 FAQ
The rear adjusting screw acts as a mechanical stopper that trims the retract stroke. For this model, you can shorten the effective travel by up to 75mm, providing a usable window of 925-1000mm. It only sets the end position and does not lock the load without live air pressure.
At an operating pressure of 0.9 MPa, the SAIJ200X1000-75 provides a push force of 28274N and a pull force of 15080N. The maximum push force reaches 3204 kgf at 1.0 MPa.
