About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-100S
The AirTAC SAIJ200X115-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 15-115 mm. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suited for heavy-duty press operations. The barrel is extruded aluminum with sensor grooves on both sides, and the rod is SUS420J2 stainless steel for superior corrosion resistance.
This model features a PT tapered port and a built-in magnet (-S) for use with CMSE reed and DMSE electronic sensors. The rear mechanical stopper allows you to dial back the nominal 115 mm stroke by up to 100 mm without adding external stops. Remember the adjuster acts only as a travel stop; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-100S Is Used
Heavy-Duty Press Tuning
Dial in the exact 15-115 mm end-position during heavy press commissioning without swapping cylinders or adding external mechanical stops.
Product Size Changeover
Quickly adjust the travel window on automated lines handling varying product sizes, ensuring precise positioning for each new batch.
Robotic End Effectors
Provide high-force actuation with variable stroke limits for large robotic grippers, utilizing the -S magnet for DMSE electronic position feedback.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-100S the Right Cylinder?
Choose this 200 mm bore when your application requires up to 3204 kgf at 1.0 MPa, stepping up from a 160 mm bore that provides 10053 N push force at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers. For load-holding without live air, consider an external pilot-operated check valve or the AirTAC SAIL lock cylinder instead.
Configuration: 200 mm bore, 115 mm stroke, 100 mm adjustment, PT port, SUS420J2 rod, -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Although the stroke is under 300 mm, the massive 40 mm rod and M36x2 thread handle high side loads, but long unsupported loads still need 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 SAIJ200AX115-100S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel from the nominal 115 mm down to as little as 15 mm, creating a 15-115 mm adjustable window. It is a travel stop, not a lock, and does not hold the load without live air.
