About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-20
The AirTAC SAIJ100X750-20 is a double-acting ISO 15552 profile cylinder built for applications requiring exact end-position calibration. It features a 100mm bore and a 750mm stroke, paired with a rear adjusting screw that allows you to trim the effective travel back by up to 20mm. This creates a 730-750mm usable window, enabling fine-tuning during commissioning without swapping out the cylinder or adding external stops. At 0.5 MPa, it delivers 3927N of push force and 3681N of pull force.
The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, though this specific configuration omits the magnet option. It uses a G1/2 port and a 25mm carbon steel rod with an M20x1.5 thread. Because the stroke is 750mm, the long unsupported rod requires an external guide to prevent side-loading damage. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-20 Is Used
Machine Setup Calibration
Dial in the exact 730-750mm end-of-stroke position during initial machine commissioning to ensure perfect alignment without machining spacers.
Product Size Changeovers
Quickly adapt the cylinder's retract stop on packaging lines when processing different product lengths, using the 20mm adjustment range to accommodate size variations.
Long-Stroke Material Handling
Move heavy loads along a 750mm path with 3927N of thrust at 0.5 MPa, relying on the adjustable stop to fine-tune the resting position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-20 the Right Cylinder?
Choose this 100mm bore adjustable cylinder when your machinery requires precise end-stop tuning at setup or during product changeovers. If your application needs less force, stepping down to an 80mm bore provides 2513N at 0.5 MPa, but the 100mm bore is necessary to reliably move loads requiring nearly 4000N. The adjustable 730-750mm travel window is ideal for dialing in exact positioning without mechanical rework.
When replacing an ISO 15552 cylinder, match the 100mm bore, 750mm stroke, 20mm adjustment range, G1/2 PT port, and your required mounting style from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). For any 750mm stroke, you must use an external guide to support the rod and prevent binding. If your machine requires the load to stay in place during a complete air pressure loss, note that this cylinder's adjuster is only a stop; you would need a SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock.

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 SAIJ100X750-20 FAQ
At an operating pressure of 0.5 MPa, this 100mm bore cylinder generates 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N.
The rear adjuster screw lets you shorten the effective stroke by up to 20mm, providing a usable travel window of 730-750mm. This stopper fine-tunes the end position but does not lock or hold the load without continuous air pressure.
