About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-30S
The AirTAC SAIJ200X150-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers immense thrust, generating 15708N of push force and 15080N of pull force at 0.5 MPa. By integrating a rear adjusting screw, this 150 mm nominal stroke model provides a usable travel window of 120-150 mm, allowing you to dial in the exact retract end position during commissioning without adding external stops.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for position sensing. It operates at speeds of 30-500 mm/s and uses a G3/4 port. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic sensors to confirm piston position accurately.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-30S Is Used
Heavy Press Tuning
Fine-tune the 120-150 mm travel window on heavy presses during setup, ensuring precise contact without swapping cylinders or adding external mechanical stops.
Product Diversion
Adjust the retract end-stop on the fly to accommodate varying package sizes on a conveyor line, using the 30 mm adjustment range to change product routing depth.
Machine Changeover
Rapidly reconfigure large clamping fixtures by dialing in the rear screw, adapting the 15708N stroke endpoint for different product dimensions without replacing hardware.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-30S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires up to 15708N push force at 0.5 MPa, stepping up significantly from the 125 mm bore which provides 6136N. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, offering fine-tuning that a fixed-stroke SAI cylinder cannot provide. For an exact ISO 15552 replacement match, verify the 150 mm stroke, 30 mm adjustment range, PT tapered port thread, and the required -S magnet.
With a 150 mm stroke, the 40 mm diameter rod and M36x2 thread provide robust support, though any long unsupported loads should still use an external guide to prevent side-loading damage. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.
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 SAIJ200AX150-30S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 28274N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 150 mm down to 120 mm. This creates a 120-150 mm usable travel window for fine-tuning the end position, though it does not lock the load without live air pressure.
