About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-20
The AirTAC SAIJ100X65-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. Its integrated PT G1/2 port and 25mm carbon steel rod provide robust performance for demanding industrial setups. By using the external adjusting screw, you achieve a usable travel window of 45-65mm, allowing precise end-position tuning without swapping out the entire unit.
This adjustable-stroke design is ideal for product-size changeovers on a packaging line, enabling rapid mechanical recalibration. The extruded aluminum barrel features sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic switches if a magnet is added later. It supports a standard mounting subset including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-20 Is Used
Machine Changeover
Dial in the 45-65mm travel window during product size changes, using the rear screw to set new end positions rapidly without changing the cylinder.
Press Fit Tuning
Fine-tune the retraction stop during commissioning to perfect the pressing depth, leveraging the 3927N push force at 0.5 MPa for reliable assembly.
Variable End Stops
Adjust the effective stroke on the fly for flexible manufacturing lines, relying on the robust 25mm carbon steel rod to handle the dynamic loads.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-20 the Right Cylinder?
Select this 100mm bore when an application requires substantial thrust—such as 3927N push at 0.5 MPa—but still needs micro-adjustments to the retract end position during commissioning. If your setup demands less force, stepping down to an 80mm bore yields 2513N push force, whereas moving up to a 125mm bore provides 6136N. Choose the SAIJ adjustable variant over a fixed SAI cylinder when you need to dial in a specific travel window (here, 45-65mm) rather than relying on a rigid hard stop.
Remember that the rear adjuster acts purely as a travel stop and does not lock the load; if you need to hold position without live air pressure, consider an external rod lock or a SAIL cylinder. To replace this ISO 15552 cylinder, match the 100mm bore, 65mm stroke, 20mm adjustment, PT G1/2 port, and your required mounting hardware.
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 SAIJ100X65-20 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the 65mm nominal stroke by up to 20mm, creating a usable travel window of 45-65mm. It functions as a mechanical stop to fine-tune the end position and is not a locking mechanism.
