About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-50
The AirTAC SAIJ100X65-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel. With a nominal 65 mm stroke and a 50 mm adjustment range, it provides a usable 15-65 mm travel window. This fine-tuning capability lets you dial in the exact end position at commissioning without swapping the hardware or adding external stops. The extruded aluminum barrel design integrates sensor grooves on both sides for straightforward position feedback.
Belonging to the 100 mm bore class, it delivers a robust 3927 N push force and 3681 N pull force at 0.5 MPa. It features a 25 mm carbon steel piston rod with an M20x1.5 thread, a G1/2 port, and 36 mm cushions at both ends. The rear adjuster acts as a travel stop to set the retract position, but it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-50 Is Used
Machine Setup & Changeover
Dial in the exact retract position within the 15-65 mm window during product changeovers without machining new hard stops or replacing the cylinder.
Variable End-Stop Positioning
Ideal for assemblies requiring a precise, adjustable physical stop at the end of the stroke, allowing operators to fine-tune the travel distance on the fly.
Heavy-Duty Clamping
Leverages the 100 mm bore's 3927 N push force at 0.5 MPa to securely hold large workpieces, while the adjuster allows precise clamping depth control.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X65-50 the Right Cylinder?
Choose this 100 mm bore unit when your application requires the 3927 N thrust at 0.5 MPa but demands precise end-position tuning over a 15-65 mm window. If your force requirements are lower, stepping down to an 80 mm bore provides 2513 N push force while saving space. Conversely, if you need significantly higher thrust, a 125 mm bore offers 6136 N. The adjustable rear screw is ideal for machine setups requiring variable end stops or frequent product-size changeovers, functioning differently from a fixed-stroke SAI cylinder. Ensure your setup matches the PT tapered port thread and the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), which omits FB, CA, CB, and CR options. Because the stroke is under 300 mm, standard side-load concerns are minimized, but always ensure the rod thread is properly aligned to prevent binding.
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 SAIJ100X65-50 FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 50 mm. This gives the 65 mm nominal stroke a usable travel window of 15 to 65 mm, allowing you to fine-tune the end position without replacing the cylinder.
At a standard 0.5 MPa operating pressure, the SAIJ100X65-50 provides 3927 N of push force and 3681 N of pull force. It can deliver up to 7068 N push force at 0.9 MPa.
