About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-50S
The AirTAC SAIJ100X750-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 700-750 mm usable travel window, allowing you to dial back the 750 mm nominal stroke by up to 50 mm during commissioning. Delivering 5497 N of push force at 0.7 MPa, it handles heavy positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed and DMSE electronic switches.
This model uses a carbon steel piston rod with an M20x1.5 thread, paired with PT tapered ports (G1/2) for reliable pneumatic connections. It supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB and CA/CB options. The rear adjuster acts purely as a travel stop to fine-tune deceleration, not as a load lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-50S Is Used
Product Changeover
Dial in the 50 mm stroke adjustment on packaging lines to accommodate varying carton sizes without replacing the entire cylinder assembly.
End-Position Calibration
Fine-tune the retract stop during machine commissioning to achieve exact 700 to 750 mm travel, ensuring precise mechanical alignment.
Heavy Material Handling
Leverage the 5497 N push force at 0.7 MPa to move heavy pallets or fixtures, using the adjustable end-stop to prevent overtravel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-50S the Right Cylinder?
Choose this 100 mm bore when a 63 mm cylinder (2182 N push at 0.5 MPa) is insufficient, or step up to 125 mm (8590 N push at 0.5 MPa) for heavier loads. The 50 mm adjustable window is ideal for product changeovers, letting you fine-tune the end position without adding external stops or swapping a fixed-stroke SAI cylinder. For strokes of 750 mm, an external guide is recommended to prevent side-load damage to the M20x1.5 rod.
Because the rear screw is a stop and the air cushions only manage deceleration, this cylinder will not hold a load without live air. For fail-safe load holding, select the SAIL (air-released lock) or BSAI (clamp-lock) series. This SAIJ100X750-50-S is dimensionally interchangeable per ISO 15552, uses PT ports, includes a magnet for sensors, and operates at 30-800 mm/s.
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 SAIJ100X750-50S FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 3681 N of pull force. It can deliver a maximum push force of 7068 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 750 mm down to 700 mm. It sets the end position and deceleration point, but it does not lock or hold the load without continuous air pressure.
