About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-75
The AirTAC SAIJ200X115-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the retract end-position without adding external stops. With a nominal 115 mm stroke and a 75 mm adjustment range, the usable travel window spans 40 to 115 mm. This massive 200 mm bore generates 15708 N of push force at 0.5 MPa and up to 28274 N at 0.9 MPa, making it ideal for heavy-duty press operations.
This specific configuration uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and ships with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic solid-state sensors. It supports a speed range of 30-500 mm/s and uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-75 Is Used
Heavy-Duty Pressing
Delivers up to 28274 N of force at 0.9 MPa for assembling large components, with the 75 mm adjuster allowing precise bottoming-out height changes between product families.
Machine Changeover
Quickly reconfigure the retract distance within the 40-115 mm window during format changeovers without disassembling the ISO 15552 mounting hardware.
Large-Part Conveyance
Provides robust actuation for heavy material handling lines, using the rear stopper to dial in the exact push distance for varying pallet sizes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-75 the Right Cylinder?
Select this 200 mm bore when your application requires extreme thrust, such as 15708 N at 0.5 MPa, but needs on-the-fly travel tuning to accommodate varying product sizes. If you need less force, dropping to a 160 mm bore yields 10053 N at 0.5 MPa, whereas stepping up is not possible as this is the largest standard SAIJ size. The 75 mm adjustment window is particularly useful for machine changeovers, letting you dial in the exact 40-115 mm end-stop without swapping the cylinder.
Because this is a double-acting cylinder, the rear adjuster acts purely as a mechanical travel stop and does not hold the load without continuous live air pressure. For fail-safe load holding, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock. To replace an ISO 15552 cylinder, match the 200 mm bore, 115 mm stroke, 75 mm adjustment, PT ports, and the desired mounting bracket. Note that a 40 mm diameter rod with an M36x2 thread handles high side loads well, but any stroke over 300 mm on this bore would 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 SAIJ200AX115-75 FAQ
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 115 mm nominal stroke by up to 75 mm, providing an effective usable travel window of 40 to 115 mm. It is a stop, not a lock, so it will not hold the load without live air pressure.
