About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-40S
The AirTAC SAIJ200X135-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end-of-travel position during commissioning. Based on a 135 mm nominal stroke, the external stopper provides a 40 mm trim range, yielding a usable travel window between 95 and 135 mm. This eliminates the need to physically swap the cylinder or bolt on external stops when dialing in a machine setup. It delivers substantial thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa.
Built for demanding environments, this specific configuration features an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance compared to standard carbon steel. The -S suffix denotes an integrated magnet for position sensing, designed to work seamlessly with AirTAC CMSE reed and DMSE solid-state switches mounted into the dual-side sensor grooves on the extruded aluminum barrel. Fluid is filtered air, operating at pressures from 0.15 to 1.0 MPa.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-40S Is Used
Heavy Press Fine-Tuning
Ideal for heavy pressing operations where the exact end-position needs micro-adjustments during initial commissioning without disassembling the tooling.
Product Changeover Stops
Perfect for conveyor lines handling varying product sizes, allowing operators to dial the stroke back from 135 mm down to 95 mm to accommodate shorter packages.
Automated Assembly Dial-In
Used in automated assembly stations to set precise engagement depths for large components, leveraging the 40 mm adjustment window to perfect the final hit point.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-40S the Right Cylinder?
Selecting this 200 mm bore model is appropriate when your application requires up to 15708 N of push force at 0.5 MPa, or up to 21991 N at 0.7 MPa. If your force 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 and efficient footprint. The primary advantage of choosing the SAIJ adjustable series over a fixed-stroke SAI cylinder is the ability to accommodate product size changes on a production line by simply turning the rear screw to shift the 95-135 mm travel window, rather than replacing the entire actuator.
This SKU uses a PT tapered port thread and supports the standard SAIJ mounting set, including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that the rear adjuster functions strictly as a travel stop and works alongside the variable air cushions to decelerate the load; it does not hold the load without live air pressure. For true pneumatic load-holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) series. Since the stroke is 135 mm, side-load risks are minimal, but external guiding is always recommended for heavy loads.
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 SAIJ200AX135-40S FAQ
The rear adjusting screw acts as an external stopper that trims the retract travel. For this model, the 40 mm adjustment range allows the effective stroke to be shortened from the 135 mm nominal down to a minimum of 95 mm, providing a 95-135 mm usable window.
At 0.5 MPa, it provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N. The maximum operating pressure is 1.0 MPa.
