About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-10S
The AirTAC SAIJ100X135-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 125 to 135 mm for precise end-position tuning during commissioning. Built with a SUS420J2 stainless steel rod (code A) and an integrated magnet for position sensing, it delivers a robust 5497 N push force at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides, allowing straightforward mounting of CMSE reed or DMSE electronic solid-state switches.
This adjustable-stroke model allows you to dial in the retract stop without swapping the cylinder or adding external stops, making it highly effective for product-size changeovers on a line. Fluid ports are PT tapered G1/2, and the 25 mm rod with an M20x1.5 thread provides excellent resistance to side loading, though long unsupported strokes still require an external guide.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-10S Is Used
Precision End-Stop Tuning
Dial in the exact 125-135 mm retract position during machine commissioning to perfect part seating without machining external stop blocks.
Product Size Changeover
Quickly adjust the stroke end by up to 10 mm on packaging lines handling slightly different product lengths, minimizing downtime between runs.
Heavy-Duty Forming
Leverage the 5497 N push force at 0.7 MPa for pressing or holding applications where the final end-position needs micro-adjustments on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-10S the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust, such as the 5497 N push force at 0.7 MPa or 7068 N at 0.9 MPa. If your load demands less force, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa, whereas moving up to a 125 mm bore provides 8590 N at 0.7 MPa. The adjustable 10 mm window is ideal for fine-tuning machine setup and variable end stops without the rigid commitment of a fixed-stroke SAI cylinder.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 100 mm bore, 135 mm stroke, 10 mm adjustment, PT G1/2 port, and the -S magnet. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for load-holding without pneumatic pressure, consider an AirTAC SAIL lock, BSAI clamp-lock, or an external rod lock. Mounting options include the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

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 SAIJ100 Adjustable Cylinder SAIJ100AX135-10S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 10 mm, creating a usable travel window of 125 to 135 mm. It only sets the travel end and does not lock or hold the load without live air pressure.
At a 0.7 MPa operating pressure, it provides a push force of 5497 N and a pull force of 3681 N. At 0.9 MPa, the push force increases to 7068 N.
