About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-75
The AirTAC SAIJ200X400-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 325 to 400 mm. Delivering a massive 28274 N of push force at 0.9 MPa, it handles heavy-duty positioning with ease. The extruded aluminum barrel incorporates sensor grooves on both sides, though position detection requires adding a magnet (-S) to enable CMSE reed or DMSE electronic switches.
This unit utilizes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance against side loading. The rear adjuster acts purely as a mechanical stop for fine-tuning end positions during commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements without continuous air, an external rod lock, SAIL, or BSAI clamp-lock cylinder is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-75 Is Used
Heavy Press Tuning
Dial in the exact 325-400 mm end-stop during heavy press commissioning without swapping out the entire cylinder.
Product Changeover
Adjust the rear stopper on the fly to accommodate varying large product sizes on a conveyor line.
Large Machine Setup
Fine-tune the retract end position on large factory equipment to perfect the mechanical sequence.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-75 the Right Cylinder?
Choose this 200 mm bore when 0.9 MPa push force of 28274 N is necessary, or step down to the 160 mm bore if your application only requires 18095 N. The 75 mm adjustment range is ideal for product changeovers on large machinery, allowing you to dial in the exact 325-400 mm end-stop without swapping cylinders or adding external stops. Ports are PT (tapered) G3/4. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the 400 mm stroke is substantial, the M36x2 piston rod should still be guided externally to prevent excessive side-load wear, despite the robust rod diameter. When replacing an ISO 15552 cylinder, match the 200 mm bore, 400 mm stroke, 75 mm adjustment, PT G3/4 port, and desired mounting interface. 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 SAIJ200AX400-75 FAQ
At an operating pressure of 0.9 MPa, this 200 mm bore cylinder generates 28274 N of push force and 2268 N of pull force. It can reach a maximum push force of 15708 N at 0.5 MPa.
The rear adjuster screw lets you mechanically shorten the effective travel from 400 mm down to 325 mm. This stopper is used for fine-tuning end positions during setup but does not hold the load without live air pressure.
