About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-100S
The AirTAC SAIJ200X135-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits fine-tuning of the retract end position. With a 135 mm nominal stroke and a 100 mm adjustment range, it provides a usable travel window of 35 to 135 mm. Belonging to the 200 mm bore class, it delivers substantial thrust, yielding 15708 N push and 15080 N pull at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides, and this unit includes a magnet (-S) for use with CMSE reed and DMSE electronic switches.
This model is equipped with an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and features PT tapered port threads (G3/4). The rear adjustment screw acts purely as a mechanical stop to decelerate and set the travel end; it does not lock or hold the load without live air pressure. For load-holding requirements without continuous air, an external rod lock or related types like SAIL or BSAI should be specified.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-100S Is Used
Heavy Press Tuning
Dial in the exact 35 to 135 mm pressing distance during machine setup without replacing the cylinder or adding external mechanical stops.
Product Changeover
Adjust the retract end position on the fly to accommodate different package sizes or pallet widths on a high-thrust automation line.
End-Position Calibration
Fine-tune the end-of-travel stop during commissioning to compensate for mechanical wear or sensor drift over time.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-100S the Right Cylinder?
Selecting this 200 mm bore adjustable-stroke cylinder is ideal when an application demands 15708 N of push force at 0.5 MPa and requires variable end-stops for product size changeovers. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N push at 0.5 MPa. The adjustable stroke is chosen over a fixed SAI cylinder when you need to fine-tune the end position at commissioning without swapping the cylinder or adding external stops. Because the 135 mm stroke is below the 300 mm threshold, a side-load guide is less critical, but the M36x2 rod thread and 40 mm rod diameter still handle considerable side loads.
To replace this ISO 15552 cylinder accurately, match the 200 mm bore, 135 mm nominal stroke, 100 mm adjustment code, PT G3/4 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR. It operates at 30-500 mm/s and uses 50 mm variable air cushions at both ends.

- ✓ 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 SAIJ200AX135-100S FAQ
As a 200 mm bore cylinder, it provides a push force of 15708 N and a pull force of 15080 N at 0.5 MPa. At the maximum operating pressure of 1.0 MPa, it delivers a maximum push force of 3204 kgf.
The rear adjuster screw allows you to trim the effective stroke back by up to 100 mm from the 135 mm nominal stroke, creating a usable travel window of 35 to 135 mm. The adjuster acts as a travel stop and does not lock the load without live air pressure.
