About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X400-100S
The AirTAC SAIJ200X400-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa, making it suitable for heavy-duty industrial applications. The integrated -S magnet allows for position sensing with AirTAC CMSE reed and DMSE electronic switches. A PT tapered port thread ensures a tight pneumatic connection.
This model provides a usable travel window of 300 to 400 mm, allowing you to dial back the stroke by up to 100 mm during machine setup. The carbon steel rod and M36x2 thread offer high tensile strength, but with a 400 mm stroke, an external guide is recommended to manage side loads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.

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 SAIJ200X400-100S Is Used
Heavy Press Tuning
Dial in the exact 300 to 400 mm end position for large pressing operations without swapping out the entire cylinder or adding external mechanical stops.
Product Changeover
Quickly adjust the stroke length by up to 100 mm on a packaging line to accommodate different product sizes during production line changeovers.
Machine Setup
Fine-tune the retracted end position during initial machine commissioning to perfectly align heavy 28274N loads with downstream tooling.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X400-100S the Right Cylinder?
The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR brackets.
The rear adjuster acts solely as a travel stop and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider an AirTAC SAIL or BSAI cylinder, or use an external pilot-operated check valve. This adjustable design is preferred over a fixed-stroke SAI cylinder when product changeovers require varying the end-stop distance quickly at commissioning.
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 SAIJ200X400-100S FAQ
It operates at a speed range of 30-500 mm/s.
The rear adjuster allows you to shorten the nominal 400 mm stroke by up to 100 mm, providing an effective travel window of 300 to 400 mm. It functions as a mechanical stop and does not lock the load without live air pressure.
