About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-75S
The AirTAC SAIJ200X300-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches. An extruded aluminum barrel houses sensor grooves on both sides for flexible mounting.
This model features a 300 mm nominal stroke that can be fine-tuned back by up to 75 mm, creating a usable travel window of 225-300 mm. It uses a PT tapered port and a SUS420J2 stainless steel rod (code A) for superior corrosion resistance. The rear screw acts purely as a travel stop for end-position tuning at commissioning, not as a load lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-75S Is Used
Heavy Press Tuning
Fine-tune the 225-300 mm pressing depth on heavy assemblies during commissioning without adding external mechanical stops.
Product Changeovers
Quickly adjust the retract end-position by up to 75 mm to accommodate different product sizes on the same production line.
Automated Forming
Leverage 15708 N of thrust at 0.5 MPa for forming operations while relying on the SUS420J2 rod in harsh environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-75S the Right Cylinder?
Choose this 200 mm bore when an ISO 15552 footprint demands extreme force, such as pressing or heavy lifting, offering 15708 N push at 0.5 MPa. If your application requires less force, stepping down to a 160 mm bore yields 10053 N. The adjustable stroke is ideal for product changeovers, allowing you to dial in the exact 225-300 mm end-stop without swapping cylinders. Because the 300 mm stroke is substantial, the 40 mm rod and M36x2 thread provide rigidity, but an external guide is recommended to manage side loads on long travels.
To match this cylinder exactly, specify: 200 mm bore, 300 mm stroke, 75 mm adjustment, PT port, SUS420J2 rod, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Remember that the rear adjuster and air cushions do not hold loads without live air; for dead-air holding, 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 SAIJ200AX300-75S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster screw allows you to shorten the effective travel from its 300 mm nominal stroke, providing a usable window of 225-300 mm. The adjuster acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
