About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-10S
The AirTAC SAIJ100X750-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 740-750 mm usable travel window, allowing you to trim the effective stroke by up to 10 mm during commissioning without adding external stops. This 100 mm bore generates 7068 N of push force at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
This unit includes a standard carbon steel piston rod and a magnet for AirTAC CMSE reed and DMSE solid-state sensors. It uses PT tapered port threads and features variable air cushions at both ends to decelerate the load. The rear adjuster acts purely as a mechanical stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-10S Is Used
Machine Changeover
Dial in the exact 740-750 mm end position when switching between product sizes on an automated line, avoiding mechanical shim changes.
Material Push-Off
Provides the 7068 N push force at 0.9 MPa needed to eject heavy parts, with the rear stopper allowing 10 mm of position correction.
Commissioning Calibration
Fine-tune the travel limit during setup to prevent crashes, letting the standard air cushion absorb the remaining kinetic energy.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-10S the Right Cylinder?
Choose this 100 mm bore when you need substantial thrust, such as the 5497 N push force at 0.7 MPa it provides. If your application requires less force, stepping down to an 80 mm bore yields 4523 N at 0.9 MPa, whereas moving up to a 125 mm bore offers 11045 N at 0.9 MPa. The adjustable stroke is ideal for fine-tuning end positions on product changeovers, whereas a fixed SAI cylinder requires shims or external stops for similar adjustments.
Because the 750 mm stroke is long, the 25 mm rod diameter and M20x1.5 rod thread will still experience leverage forces; an external guide is recommended to prevent side-loading damage. This SAIJ100X750-10-S is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. For load-holding without live air, select a SAIL or BSAI cylinder instead of relying on the rear stopper.

- ✓ 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 SAIJ100X750-10S FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder provides 7068 N of push force and 6625 N of pull force. At 0.5 MPa, it delivers 3927 N push and 3681 N pull force.
The rear adjuster screw lets you shorten the 750 mm nominal stroke by up to 10 mm, creating a 740-750 mm travel window. It acts as a mechanical stop to fine-tune the end position and does not lock or hold the load without continuous air pressure.
