About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-75S
The AirTAC SAIJ100X650-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 5497N push force at 0.7 MPa, utilizing a 25mm carbon steel rod and G1/2 port. The integrated -S magnet enables precise position detection with CMSE reed and DMSE electronic sensors.
This model provides a 575-650mm usable travel window, allowing you to trim up to 75mm off the 650mm nominal stroke. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-75S Is Used
Variable End-Stop Machining
Dial in the exact 575-650mm clamping position on machining fixtures to accommodate part variations without adding external stop blocks.
Machine Changeover
Quickly reconfigure automated assembly lines for new product sizes by turning the rear adjuster screw during setup.
Diversion Gate Tuning
Fine-tune the extended stroke length on sorting conveyors to perfectly position pushers for different package dimensions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-75S the Right Cylinder?
Choose this adjustable-stroke cylinder when your machine setup requires variable end-stops or fine-tuning during commissioning without swapping out the entire unit. If you need higher force, stepping up to a 125mm bore yields 8590N at 0.7 MPa; if less force is acceptable, an 80mm bore provides 3518N. Because the 650mm stroke is substantial, long unsupported travel demands an external guide to manage side-load and prevent rod binding.
The rear adjuster acts purely as a mechanical stop to set deceleration, not as a lock. A plain SAIJ cylinder will not hold its load without live air pressure. For secure load-holding, consider the SAIL lock or BSAI clamp-lock variants. This profile cylinder is dimensionally interchangeable per ISO 15552 mounting interfaces, using a PT tapered port thread.
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 SAIJ100X650-75S FAQ
At 0.7 MPa operating pressure, this 100mm bore cylinder generates 5497N of push force and 3681N of pull force. The maximum thrust is 801 kgf at 1.0 MPa.
The rear adjuster allows you to shorten the 650mm nominal stroke by up to 75mm, creating a 575-650mm usable travel window. This stop only sets the end position and does not lock the load without live air.
