About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X50-10
The AirTAC SAIJ100X50-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5MPa. It features a carbon steel piston rod and PT tapered ports. By turning the rear stopper screw, you can fine-tune the effective travel within a 40-50mm usable window, eliminating the need to swap hardware during machine commissioning.
This extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. It supports AirTAC CMSE reed and DMSE electronic sensors, though this specific SKU is configured without a magnet. The rear adjuster functions strictly as a travel stop to set deceleration, not as a lock, meaning it will not hold a load without continuous live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X50-10 Is Used
Precision End-Stop Tuning
Dial in the exact 40-50mm travel distance during machine commissioning to perfect part seating without machining new hard stops.
Product Size Changeover
Quickly adjust the rear screw on the line when switching to a slightly different product size, saving valuable setup time.
High-Force Positioning
Leverage the 3927N push force at 0.5MPa to move heavy pallets into place while fine-tuning the final resting position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X50-10 the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder (providing 2513N push at 0.5MPa) lacks the necessary thrust, but step up to a 125mm bore if your application requires 6136N. The 10mm adjustment range is ideal for dialing in exact end positions during product changeovers without adding external stops. For load-holding requirements without live air, consider an AirTAC SAIL or BSAI cylinder instead of relying on the adjuster.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 50mm nominal stroke, 10mm adjuster, PT port threads, and standard carbon steel rod. Because the nominal stroke is under 300mm, external side-load guides are less critical here than on longer strokes, but the robust M20x1.5 rod thread still handles substantial side loads. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100X50-10 FAQ
At 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7MPa, the push force increases to 5497N.
The rear stopper screw allows you to shorten the 50mm nominal stroke by up to 10mm, creating a 40-50mm usable travel window. It acts as a mechanical stop for end-position tuning and is not a locking device.
