About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-30S
The AirTAC SAIJ200X270-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 240 to 270 mm without swapping out the unit. Built with a robust 40 mm carbon steel rod and a PT tapered G3/4 port, it delivers immense thrust up to 15708 N at 0.5 MPa, making it suitable for heavy-duty industrial tasks.
This model includes a magnet (-S) for seamless integration with AirTAC CMSE reed and DMSE electronic solid-state sensors via the dual-side extruded aluminum barrel grooves. The rear adjuster functions strictly as a travel stop to dial in end positions during commissioning; it is not a locking mechanism, so live air pressure is required to hold the load.

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 SAIJ200X270-30S Is Used
Heavy Press Tuning
Dial in the exact 240-270 mm travel during heavy press commissioning to accommodate material thickness variations without external stops.
Product Changeover
Adjust the rear stopper on the fly when switching production lines to different sized parts, saving time on machine setup.
Variable End Stops
Set precise retraction end-points for heavy conveyor sorting arms where the exact resting position shifts based on payload dimensions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-30S the Right Cylinder?
Selecting the SAIJ200X270-30-S is optimal when your machinery requires extreme force and precise end-position tuning during changeovers. Conversely, this 200 mm bore is the top choice when maximum output is paramount. The adjustable 30 mm trim allows operators to dial in the exact 240-270 mm travel distance on-site, avoiding the need to stock multiple fixed-stroke SAI cylinders for varying product sizes.
Because this cylinder features a 270 mm stroke, the 40 mm rod and M36x2 thread provide substantial rigidity, but any long, unsupported heavy load still requires an external guide to prevent side-load damage. This adjustable-stroke variant uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. For applications that must hold position without continuous air pressure, consider the SAIL or BSAI series instead.
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 SAIJ200X270-30S FAQ
At the maximum pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the nominal 270 mm stroke by up to 30 mm, creating a usable travel window of 240 to 270 mm. This stopper only limits the travel distance and does not lock or hold the load without live air pressure.
