About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X30-20
The AirTAC SAIJ200X30-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a substantial 15708N thrust at 0.5 MPa and uses a PT tapered G3/4 port. The built-in rear stopper allows you to trim the 30mm nominal stroke back by up to 20mm, creating a highly precise 10-30mm usable travel window for exact end-position tuning during commissioning.
This adjustable-stroke design eliminates the need to bolt on external stops or swap cylinders when adapting to minor product-size changes on a line. The adjuster acts purely as a travel stop and works with the variable air cushion to decelerate the load at the retract end. It does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series. The extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X30-20 Is Used
Heavy Press Fine-Tuning
Dial in the exact 10-30mm travel window on heavy pressing tasks without swapping cylinders or adding external mechanical stops.
Product-Size Changeover
Quickly adapt the retract end-position on a production line when product dimensions change, using the rear screw for rapid setup.
Commissioning End-Stop
Achieve precise end-position tuning at machine commissioning by trimming the stroke up to 20mm to hit the exact target location.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X30-20 the Right Cylinder?
Select this 200mm bore model when your application requires maximum push force, delivering 15708N at 0.5 MPa or 21991N at 0.7 MPa. If your setup needs less force, stepping down to a 160mm bore yields 10053N at 0.5 MPa. The SAIJ200X30-20 is chosen over a fixed SAI cylinder when you need variable end-stops for machine setup and changeover. To replace an ISO 15552 cylinder, match the 200mm bore, 30mm stroke, 20mm adjustment, G3/4 PT port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the 40mm rod and M36x2 thread handle high side loads, but long unsupported strokes still require an external guide.
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 SAIJ200X30-20 FAQ
At 0.5 MPa, the 200mm bore provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster acts as a mechanical stop that lets you shorten the 30mm nominal stroke by up to 20mm. This creates a 10-30mm usable travel window for fine-tuning the end position without replacing the cylinder.
