About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-10S
The AirTAC SAIJ200X135-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 125 to 135 mm. It delivers substantial thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa. This bore size reaches a maximum output of 3204 kgf at 1.0 MPa, making it suitable for heavy-duty industrial movements.
This specific SKU features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and includes a magnet (-S) for position sensing. The rear adjuster acts as a mechanical stop to fine-tune the end position at commissioning without swapping the cylinder or adding external stops. It uses PT tapered ports and offers adjustable air cushions at both ends to manage deceleration.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-10S Is Used
Heavy Pressing Operations
Ideal for heavy-duty pressing and forming tasks requiring precise end-position tuning to accommodate material thickness variations during machine setup.
Large Product Diversion
Provides adjustable travel for diverting large or heavy products on a conveyor line, allowing the stroke to be dialed back 10 mm for different package sizes.
Industrial Machine Changeover
Enables quick product-size changeovers on heavy industrial machinery by fine-tuning the retract end position without swapping out the entire actuator.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-10S the Right Cylinder?
Choose this 200 mm bore when your application requires extreme force that smaller bores cannot provide, such as stepping up from a 160 mm bore that only offers 10053 N push force at 0.5 MPa. The adjustable stroke is selected when you need variable end-stops for product changeovers, allowing you to dial back the stroke by up to 10 mm without changing the cylinder. For load-holding without live air pressure, note that the rear adjuster is a travel stop and not a lock; you should consider the SAIL or BSAI series, or an external pilot-operated check valve. To match this ISO 15552 replacement cylinder, specify: 200 mm bore, 135 mm stroke, 10 mm adjustment, PT G3/4 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and a magnet for CMSE or DMSE sensors.
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 SAIJ200AX135-10S 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 delivers a peak output of 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 135 mm nominal stroke by up to 10 mm, creating a 125 to 135 mm usable travel window. It sets the end position but does not lock the load without live air pressure.
