About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-10S
The AirTAC SAIJ200X75-10-S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty applications. It features a rear stroke adjuster that allows you to trim the effective travel, creating a precise 65-75 mm usable window from the 75 mm nominal stroke without adding external stops. Equipped with a SUS420J2 stainless steel rod and PT tapered ports, it delivers massive thrust, generating 15708 N of push force at 0.5 MPa and up to 28274 N at 0.9 MPa.
This adjustable-stroke design allows fine end-position tuning during commissioning or product changeover. The rear screw mechanism acts as a travel stop to set the retract position, but it does not lock or hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-10S Is Used
Heavy Press Tuning
Dial in the exact 65-75 mm retract stop during machine setup to accommodate varying material thicknesses in heavy-duty pressing operations without external spacers.
Product Changeover
Quickly adjust the end-stop position on a production line when switching between product sizes, saving commissioning time by using the rear screw rather than repositioning the whole cylinder.
Automated Assembly End-Stop
Set precise retract limits for heavy automated assembly tooling, using the 28274 N of available thrust at 0.9 MPa to securely seat large components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-10S the Right Cylinder?
Select this 200 mm bore cylinder when your application requires extreme force combined with variable end-stop positioning. If your thrust requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, which may offer a more compact footprint. Choose the SAIJ adjustable version over a fixed-stroke SAI when you need on-the-fly end-position adjustments rather than swapping the entire cylinder. To match this ISO 15552 footprint for a direct replacement, specify: 200 mm bore, 75 mm stroke, 10 mm adjustment, PT port threads, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting options, and a -S magnet.
Because the 40 mm rod diameter and M36x2 rod thread carry high side-load capacities, this cylinder handles robust mechanics well. However, even with a sturdy rod, any stroke of 300 mm or more requires an external guide to prevent binding. The dual-side sensor grooves ensure flexible mounting for your CMSE or DMSE switches.

- ✓ 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 SAIJ200AX75-10S 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 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw acts as a travel stop that lets you shorten the effective stroke by up to 10 mm. This creates a usable travel window of 65-75 mm, allowing fine-tuning of the retract end position during commissioning without replacing the cylinder.
