About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-10S
The AirTAC SAIJ200X300-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 290-300 mm from its 300 mm nominal stroke. It delivers immense thrust, generating 21991N of push force and 15080N of pull force at 0.7 MPa. This bore size utilizes a robust 40 mm piston rod and G3/4 ports.
This configuration includes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance over standard carbon steel. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position, meaning it will not hold the load safely without continuous live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-10S Is Used
Heavy Press Tuning
Dial in the exact 290-300 mm end-stop during heavy press commissioning to accommodate material thickness variations without adding external stopper blocks.
Pallet Changeover
Adjust the retract position by up to 10 mm on the fly to handle different pallet sizes on a high-thrust conveyor line.
Large Assembly Setup
Fine-tune the stroke end-position during large-scale assembly machine setup, leveraging the 21991N push force to seat heavy components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-10S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when an application requires extreme force, as stepping down to a 160 mm bore drops the 0.7 MPa push force to 14074N. The 10 mm adjustable stroke is ideal for fine-tuning end positions during machine commissioning or product changeovers without swapping the physical cylinder. To replace this unit, match the 200 mm bore, 300 mm stroke, 10 mm adjustment, PT threaded G3/4 ports, SUS420J2 rod, and -S magnet. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 300 mm stroke is lengthy, the 40 mm rod still requires an external guide to prevent excessive side-loading on the barrel. For load-holding without live air, use an external rod lock or pilot-operated check valve, as the adjuster is not a brake.
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 SAIJ200AX300-10S FAQ
At a 0.7 MPa operating pressure, this 200 mm bore cylinder provides 21991N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, it achieves 3204 kgf.
The rear adjuster screw lets you shorten the 300 mm nominal stroke by up to 10 mm, creating a 290-300 mm travel window. It functions as a mechanical stop for end-position tuning and does not lock or hold the load without live air pressure.
