About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-50
The AirTAC SAIJ200X200-50 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. It features a robust 200 mm bore generating 15708 N of push force at 0.5 MPa, paired with a 200 mm nominal stroke that can be dialed back by up to 50 mm. This yields a usable travel window of 150-200 mm, allowing you to trim the retract position at commissioning without swapping hardware.
This variant is equipped with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet for position sensing. An external rear stopper mechanism handles the stroke adjustment, while standard variable air cushions manage end-of-travel deceleration.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-50 Is Used
Heavy Press Tuning
Fine-tune the 150-200 mm travel window during machine setup to precisely dial in heavy pressing operations without machining new stopper blocks.
Product Changeover
Adjust the retract end-position on the fly to accommodate different product sizes moving down a high-thrust transfer line.
Assembly Station Setup
Leverage the 15708 N push force at 0.5 MPa to seat large components, using the rear stopper to trim the final end-position accurately.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-50 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application demands substantial thrust, such as 15708 N push or 15080 N pull at 0.5 MPa. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, which may save space and air consumption. The adjustable stroke is ideal for product changeovers on a line, enabling variable end-stops without adding external stops. For any stroke of 300 mm or more, ensure an external guide supports the load to prevent excessive side-loading on the rod.
To match this cylinder as an ISO 15552 replacement, confirm the 200 mm bore, 200 mm stroke, 50 mm adjustment range, PT port threads, and the absence of a magnet. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, consider the SAIL or BSAI series.

- ✓ 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 SAIJ200AX200-50 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster acts as an external stopper that allows you to shorten the 200 mm nominal stroke by up to 50 mm, creating a usable travel window of 150-200 mm. It sets the end position but does not lock the load without live air pressure.
