About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X45-10S
The AirTAC SAIJ200X45-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. With a nominal 45 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 35 to 45 mm, allowing you to dial in the exact retract position at commissioning without adding external stops.
This variant includes a standard carbon steel piston rod and a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting, and the G3/4 PT ports ensure high airflow for the 30-500 mm/s speed range.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 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 SAIJ200 Adjustable Cylinder SAIJ200X45-10S Is Used
Machine Changeover
Quickly reconfigure the retract end-stop from 35 to 45 mm during product size changes on a line, eliminating the need to physically swap cylinders or reposition external stop blocks.
High-Force Clamping
Secures heavy industrial workpieces with extreme holding power while live air is applied, using the rear adjuster to fine-tune the clamp position to the exact required dimension.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X45-10S the Right Cylinder?
If you do not need that much power, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, which might better suit medium-duty tasks while saving space. The adjustable stroke is specifically useful for machine changeovers, letting you fine-tune the end position on the fly instead of swapping out a fixed-stroke SAI cylinder.
Because the 45 mm stroke is short, side-loading is less of a concern here, but always ensure rigid mounting to handle the immense forces. Remember that the rear adjuster acts only as a travel stop and cannot hold the load without live air pressure; for true load-holding, consider an AirTAC SAIL or BSAI cylinder. This SAIJ model uses the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.
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 SAIJ200 Adjustable Cylinder SAIJ200X45-10S FAQ
It can deliver up to 3204 kgf at its maximum 1.0 MPa pressure.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm. This gives the 45 mm nominal stroke a usable travel window of 35 to 45 mm, enabling fine-tuning of the end position at commissioning without replacing the cylinder.
