About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-40
The AirTAC SAIJ200X600-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position during commissioning. With a 600 mm nominal stroke and a 40 mm adjustment range, it provides a usable travel window of 560-600 mm, enabling precise variable end-stops without swapping out the cylinder.
Delivering massive thrust, this 200 mm bore model outputs 15708 N of push force at 0.5 MPa and reaches 21991 N at 0.7 MPa. It features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance, PT tapered port threads, and operates at speeds of 30-500 mm/s.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-40 Is Used
Heavy Assembly Positioning
Dial in the exact 560-600 mm end-stop during machine commissioning to position heavy structural components accurately without external stopper blocks.
Product Line Changeover
Quickly adapt the cylinder stroke on a mixed-product line by turning the rear adjuster, accommodating different part lengths on the fly.
Large Press Clamping
Leverage the 15708 N push force at 0.5 MPa to secure large fabricated parts, using the adjustable travel to fine-tune the clamping depth precisely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-40 the Right Cylinder?
Choose this 200 mm bore model when your application requires extreme force that smaller bores cannot provide, such as moving heavy assemblies. If you need less force, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa. The adjustable stroke is ideal for machine setup and product changeover, allowing you to dial in the exact travel distance without adding external stops.
Because the stroke is 600 mm, the 40 mm rod diameter and long unsupported travel require an external guide to prevent excessive side-loading and premature seal wear. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an external rod lock or the AirTAC SAIL or BSAI series. This cylinder is dimensionally interchangeable per ISO 15552 mounting-interface dimensions and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 SAIJ200AX600-40 FAQ
At a 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 acts as a mechanical stop that lets you shorten the 600 mm nominal stroke by up to 40 mm, creating a usable travel window of 560-600 mm. This allows fine-tuning of the end position without replacing the cylinder.
