About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX135-40S
The AirTAC SAIJ100X135-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 135 mm nominal stroke by up to 40 mm. This creates a usable travel window of 95-135 mm, perfect for fine-tuning end positions during commissioning without swapping hardware. It delivers robust thrust, generating 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. It works seamlessly with AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions while utilizing a PT tapered port thread.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX135-40S Is Used
Machine Setup Changeover
Quickly dial in the 95-135 mm end position during product size changes without machining new stop blocks.
Variable End-Stop Positioning
Trim the stroke by up to 40 mm on the fly to accommodate varying material thicknesses in clamping tasks.
Adjustable Diverting Stroke
Fine-tune the actuator reach on a conveyor sorting arm to handle different package dimensions accurately.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX135-40S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (delivering 2513 N push at 0.5 MPa) is insufficient, but before stepping up to a 125 mm cylinder. The adjustable 95-135 mm travel window is ideal for product changeovers on a packaging line, providing variable end-stops without adding external mechanical stops. At 135 mm stroke, side-load stress is moderate, but ensuring proper external guiding will maximize seal life.
This cylinder uses a PT tapered port thread and supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ100 Adjustable Cylinder SAIJ100BX135-40S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm, providing a usable travel window of 95-135 mm. It acts as a mechanical stop to fine-tune the retract position at commissioning.
At 0.5 MPa operating pressure, it provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
