About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-10
The AirTAC SAIJ200X115-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 115 mm stroke back by up to 10 mm, yielding a precise 105-115 mm usable travel window. It delivers substantial thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it suitable for heavy-duty operations.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and utilizes a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible position detection, while the adjustable stopper allows you to fine-tune the retract end position during commissioning without adding external physical stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-10 Is Used
Heavy Press Tuning
Dial in the exact 105-115 mm retract position during heavy press commissioning without replacing the entire cylinder or adding external stopper blocks.
Product Changeover
Quickly adjust the end-stop by up to 10 mm on a packaging line when switching to a slightly different product size, minimizing machine downtime.
High-Force Positioning
Leverage the 15708 N push force at 0.5 MPa to move heavy pallets or tooling, using the rear screw to fine-tune the resting position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-10 the Right Cylinder?
Choose this 200 mm bore cylinder when an application requires up to 15708 N of thrust at 0.5 MPa; stepping down to a 160 mm bore reduces the push force to 10053 N, whereas moving up is not available in this standard series. The 10 mm rear adjustment mechanism is ideal for dialing in exact end-of-stroke positions during machine setup or product changeovers, replacing the need to physically swap out a fixed-stroke SAI cylinder.
Because the nominal stroke is 115 mm, an external guide is not strictly mandated for side loads, though the robust 40 mm rod and M36x2 thread handle significant mechanical stress. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true fail-safe load holding, consider an AirTAC SAIL or BSAI series cylinder. This model is dimensionally interchangeable per ISO 15552 mounting interface standards.
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 SAIJ200AX115-10 FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. It can reach a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective stroke from the nominal 115 mm down to as little as 105 mm, providing a 105-115 mm travel window. This stopper only sets the end position and decelerates the load; it does not lock or hold the load without continuous air pressure.
