About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-100
The AirTAC SAIJ100X300-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 300 mm nominal stroke that can be dialed back by up to 100 mm, yielding a 200-300 mm usable travel window for precise end-position tuning during commissioning. Delivering 3927 N of push force and 3681 N of pull force at 0.5 MPa, it fits heavy-duty applications.
This extruded aluminum profile barrel omits tie-rod construction and integrates sensor grooves on both sides for flexible switch placement. Without a specified -S magnet, it operates purely on pneumatic positioning, while the carbon steel rod and M20x1.5 rod thread provide robust resistance to side loads. The rear adjuster acts purely as a travel stop to fine-tune the retract position without adding external stops.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-100 Is Used
Variable Product Changeover
Dial in the exact end-stop from 200 to 300 mm when switching between different product lengths on a packaging line, avoiding mechanical rebuilds.
Heavy-Duty Pressing
Utilize the 3927 N push force at 0.5 MPa for pressing assemblies, with the 100 mm adjustment window allowing precise control over the final press depth.
Machine Commissioning
Fine-tune the retract position during initial setup using the rear stopper screw, compensating for mechanical tolerances without adding external shims.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-100 the Right Cylinder?
Choose this 100 mm bore cylinder when your application requires 3927 N of push force at 0.5 MPa and a highly variable retract endpoint. The 100 mm adjustment range is ideal for machinery that processes varying product sizes, allowing you to shift the end-stop from 200 mm to 300 mm without swapping the cylinder. If your force requirements are lower, stepping down to an 80 mm bore yields 2513 N push force at 0.5 MPa.
Because the 300 mm stroke presents a long unsupported rod extension, an external guide is recommended to prevent side-load damage to the piston. The rear adjuster and integrated air cushions decelerate the load but do not hold it without live air; for fail-safe load holding, select a SAIL or BSAI cylinder instead. This SAIJ model uses a PT tapered G1/2 port, supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, and is dimensionally interchangeable with ISO 15552 cylinders.
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 SAIJ100X300-100 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. The operational speed range is 30-800 mm/s.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 300 mm nominal stroke by up to 100 mm, creating a 200-300 mm travel window. It only sets the end position and does not lock the load without live air pressure.
