About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-50S
The AirTAC SAIJ100X750-50-S is a double-acting, adjustable-stroke ISO 15552 profile cylinder offering a 700 to 750 mm usable travel window via a rear stopper screw. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting.
Because the rear adjuster acts purely as a travel stop and the air cushions handle deceleration, this cylinder cannot hold a load without live air. For position holding, consider a SAIL pneumatic lock or BSAI clamp-lock cylinder. The robust 25 mm rod and M20x1.5 thread handle high side loads, and the PT tapered ports ensure a tight pneumatic seal.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-50S Is Used
Machine Changeover
Dial in the exact 700 to 750 mm end position during product size transitions without replacing hardware.
Commissioning Setup
Use the 50 mm rear adjustment window to perfect the end-of-travel stop during initial machine calibration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-50S the Right Cylinder?
An adjustable stroke is ideal for fine-tuning end positions during commissioning or product changeovers without swapping cylinders. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
For a 750 mm stroke, long unsupported travel increases rod deflection. Always use an external guide rail to prevent side-load damage. To replace an ISO 15552 cylinder, match the 100 mm bore, 750 mm stroke, 50 mm adjustment, G1/2 port, and -S magnet.
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 SAIJ100AX750-50S FAQ
At 0.7 MPa, push force increases to 5497 N.
The rear adjuster screw lets you shorten the effective travel from 750 mm down to 700 mm. It functions as an external stop to fine-tune the end position at commissioning without changing the cylinder.
