About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-30S
The AirTAC SAIJ200X105-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708N and pulling 15080N at 0.5 MPa, making it suited for heavy-duty positioning. The integrated -30 adjustment code creates a usable travel window of 75-105mm, allowing you to dial in the exact retract distance without swapping hardware.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for position sensing. The extruded aluminum barrel houses sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. Air cushions at both ends decelerate the heavy 40mm rod, while the rear stopper sets the final end position.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-30S Is Used
Heavy Press Tuning
Fine-tune the 75-105mm retract distance on heavy pressing tasks to accommodate material thickness variations without remounting the cylinder.
Product Changeover
Adjust the end stop quickly during production line size changes, using the rear screw to set the exact 75-105mm travel window for new pallets.
Heavy Load Positioning
Leverage the 15708N push force at 0.5 MPa to move massive fixtures into place, relying on the SUS420J2 rod for durability in harsh environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-30S the Right Cylinder?
Choose this 200mm bore when 160mm (10053N push at 0.5 MPa) lacks the necessary force for your load. The adjustable 75-105mm stroke is ideal for product changeovers, letting you fine-tune the retract end position at commissioning rather than machining external stops. If your setup requires holding a load without live air pressure, note that this rear adjuster acts only as a travel stop, not a lock; you would need an external pilot-operated check valve or a related SAIL lock cylinder.
For an exact ISO 15552 replacement, match the 200mm bore, 105mm nominal stroke, -30 adjustment, PT tapered ports, and the -S magnet. Because the stroke exceeds 300mm on larger variants, always ensure external guidance to prevent side-loading, though this 105mm stroke is well within safe standard limits. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ200AX105-30S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides a push force of 15708N and a pull force of 15080N. It can reach a maximum push force of 21991N at 0.7 MPa.
The rear adjuster allows you to shorten the 105mm nominal stroke by up to 30mm, creating a usable travel window of 75-105mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
