About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-50S
The AirTAC SAIJ200X500-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 450-500 mm. It delivers substantial thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa, making it suitable for heavy-duty positioning. The barrel is extruded aluminum with sensor grooves on both sides, and it includes a -S magnet for position detection.
This variant uses a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and features PT tapered port threads sized at G3/4. The rear adjustment screw acts purely as a mechanical stop to trim the nominal 500 mm stroke by up to 50 mm during commissioning. It is not a locking device; the cylinder relies on live air pressure to maintain its position, and the adjuster only defines the retract end-point without holding the load statically.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-50S Is Used
Heavy Press Setup
Dial in the exact 450 to 500 mm end-position during heavy press commissioning to accommodate varying material thicknesses without adding external stops.
Product Changeover
Quickly adapt the retract end-stop for different product sizes on a high-thrust line, utilizing the 50 mm adjustment range to avoid mechanical retooling.
Large Assembly Line
Leverage the 15708 N push force at 0.5 MPa to shift heavy pallets or fixtures, fine-tuning the travel window to match station index distances.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-50S the Right Cylinder?
Choose this 200 mm bore when an application requires up to 15708 N of push force at 0.5 MPa, stepping up significantly from a 160 mm bore that provides 10053 N. The adjustable 450-500 mm travel window is beneficial for machine setups requiring variable end-stops or product size changeovers without physically swapping the cylinder. Because the nominal stroke is 500 mm, the 40 mm rod and M36x2 thread carry substantial side-load capacity, but an external guide is still recommended for unsupported loads.
For load-holding applications without live air pressure, this adjuster will not suffice as a brake; consider an AirTAC SAIL or BSAI cylinder instead. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. It operates at 30-500 mm/s and supports AirTAC CMSE reed and DMSE electronic sensors via its integrated magnet.

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 SAIJ200AX500-50S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. It can reach a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the nominal 500 mm stroke by up to 50 mm, creating a usable travel window of 450 to 500 mm. This stopper only sets the end position and does not lock the load without live air pressure.
